Industrial Electronics Repair Services

Industrial electronics repair services are the backbone of successful  manufacturing facilities all over the United States. In an ever growing technological world, many manufacturers have learned that in order to increase production time and energy savings in their plant, they must partner with the best sources for their much needed industrial electronics repair services.

Many manufacturers constantly seek alternatives to repair their industrial electrical equipment on the internet, because local vendors do not always meet the demands which they place upon them.

Precision Electric service technicians have hundreds of years combined experience in the industrial manufacturing world of repair and troubleshooting.

Precision Electric repair and service technicians frequently attend training seminars all over the country because new technology and equipment is constantly being released into production lines across the globe, and Precision Electric maintains their reputation in this industry by consistently adapting to technology changes.

Precision Electric specializes in all aspects of industrial electronics repair services, and their capabilities are virtually endless because of the vast amount of equipment in production. Some of Precision Electric industrial electronics repair services include, servo motors, servo drives, variable speed drives, PCB, Programmable Logic Controllers, to encoder and tachometer alignment, custom design & custom built electrical panels and much more.

Precision Electric partners with maintenance crews from the smallest of businesses to the largest of corporations with a common ground to increase production and energy savings; while decreasing the overall downtime in production lines. Whether it be a fractional horsepower servo motor or a 1000 horsepower variable speed drive, Precision Electric consistently puts forth the same amount of effort and support in all their repair operations.

DC Electric Motor Repair

Precision Electric separates itself from other DC electric motor repair facilities in many ways. Most DC electric motor repair facilities use the assembly line method which isn’t ideal because when many people work on the same DC electric motor, and the chance of human error drastically increases.

Precision Electric designates each DC electric motor repair to a specific mechanic, so the mechanic who disassembles the DC electric motor is the same mechanic who assembles and final tests the DC electric motor.

When Precision Electric facilitates a DC electric motor repair, an initial test procedure is performed to determine cause of failure and other problems which may exist, including armature and field frame rewinds.

Precision Electric performs rewinds on-site and is known to work around the clock on emergency jobs until DC electric motors are repaired and ready to be installed back into production.

DC electric motor repair introduces additional complexities into the repair process. The addition of a commutator with brushes, and rotating armature coils subjected to centrifugal force, which aren’t factors involved in typical AC electric motor repair.

The following procedures and tests are performed at Precision Electric to guarantee a quality DC electric motor repair.

Conductive carbon dust left by worn brushes is cleaned from the armature; then each commutator is checked for grounds and bar-to-bar shorts with detailed electrical testing.

Coils are manufactured in-house to assure proper fit. This eliminates constant bending and shaping during installation which can damage coil insulation. Proper banding is critical in DC repair. This ensures that the winding is held in position during high-speed operation.

Field coils are checked using voltage drop testing. Bad fields and inter-poles are rewound in our shop on custom forms. TIG welding is available to eliminate soldered joints where design dictates.

All commutators are turned, undercut, and chamfered to provide the best possible surface for brush contact. For corrosive or other severe duty environments, commutator platinum plating is available to extend wear life (pickle-duty). Neutral setting adjustments are made during final machine testing to ensure proper operation.

All DC electric motor repair performed by Precision Electric is backed by a 12-month in service warranty. The Precision Electric in service warranty provides customers with a peace of mind knowing that their spare DC motors will be warrantied regardless of how long their spare equipment is on standby.

Servo Motor and Drive Repair

Precision Electric consistently expands it’s industrial electronics repair services because customers demand it. With the wide array of servo motors and drives in the market, a substantial need for ever-changing servo motor and drive repair services are needed.

There has always been three primary issues with servo motor and drive replacement- Servo motors and drive combinations are frequently proprietary and difficult to replace. Original Equipment Manufacturers (OEMs) retire older models of servo motor and drive equipment. The cost of replacement servo motor and drive combinations are often extremely high.

The demand of servo motor and drive repair is created by the Original Equipment Manufacturers’ ever-changing technological advancements. Most manufacturing facilities, however, often seek out servo motor and drive repair to cut down the cost associated with replacing obsolete equipment with new equipment.

The components Original Equipment Manufacturers use to build servo motor and drive combinations are often cheaply made. During a servo motor and drive repair, Precision Electric replaces these parts with quality parts that exceed the quality control of the Original Equipment Manufacturer.

What does this mean? It means that the servo motor and drive repair you receive back from Precision Electric is likely in better quality than the original equipment itself.

Using proprietary software, Precision Electric can re-align the servo motor as necessary to ensure the rewinding of the motor retains full accuracy. Precision Electric has nearly 20 years experience with servo motor and drive repair, and can also find obsolete components and parts for the toughest servo motor and drive repairs.

Precision Electric offers prompt turnaround time of servo motor and drive repair, because the ultimate goal of Precision Electric is minimizing their customer’s downtime while increasing production time.

Precision Electric facilitates servo motor and drive repair to industrial manufacturing facilities across the globe. Call Precision Electric today for a free quote of servo motor and drive repair.

Mitsubishi Servo Motor Repair

Many Mitsubishi servo motors across the globe are obsolete, which is why Mitsubishi servo motor repair has such high demand. For Mitsubishi servo motors that are not obsolete, the availability of the Mitsubishi servo motor usually exceeds the repair lead time.

Equipment failure is the number one factor in production loss for manufacturing facilities across the globe. It’s important that manufacturing facilities keep spare servo motors on the shelf, to maximize overall production. Most of Precision Electric’s customers keep rebuilt spare Mitsubishi servo motors on their shelf. Once their primary Mitsubishi servo motor fails, the spare is swapped out with the failed unit. The failed Mitsubishi servo motor is then sent to Precision Electric for routine maintenance repair.

Precision Electric routine maintenance of Mitsubishi servo motor repair can save manufacturers hundreds of thousands of dollars in production loss, as well as repair costs. Precision Electric routine maintenance consists of removing all parts of a Mitsubishi servo motor, cleaning parts and motor winding, replacement of bearings, repair bearing housings if needed, dynamic balance, testing of all electrical components, assembly of servo motor, and final test with motor.

The intent of routine maintenance is to provide manufacturing facilities with optimal production, and also to prevent Emergency or Rush repair services on Mitsubishi servo motors.

Keeping a spare Mitsubishi servo motor is the best method for manufacturing facilities to save on repair costs. If a manufacturer has a spare Mitsubishi servo motor, the failed Mitsubishi servo motor doesn’t need to be worked on around the clock until it has been completely rebuilt.

Call Precision Electric today for free quotes on routine maintenance for Mitsubishi servo motor repairs.

Eaton SVX9000 Drive Repair

The Eaton SVX9000 variable frequency drive is often seen on Sullair air compressor applications, because it provides Sullair air compressor applications with sensorless vector technology, as well as high speed output frequency up to 7200 Hz. Eaton SVX9000 variable frequency drives automatically identify motor parameters in sensorless vector mode as well as U/f mode, which keeps track of parameter changes over time. The Eaton SVX9000 allows for steady speed error, fast torque rise time, high immunity to resonance vibrations and high torque upon start up.

When Eaton SVX9000 drives fail, Eaton is known to recommend replacing the failed SVX9000 drive with a new SVX9000 drive. Customers of Precision Electric have testified that, rather than replacing the failed Eaton SVX9000 drive, a more economical solution is to have Precision Electric repair the failed Eaton SVX9000 drive.

Precision Electric has helped Certified Sullair Repair Centers save thousands of dollars by repairing their failed Eaton SVX9000 drives. Precision Electric has also saved Certified Sullair Service Centers time, because the overall repair time of an Eaton SVX9000 drive is far less than the average lead time of an exact Eaton SVX9000 drive replacement. Eaton SVX9000 drive repair is an asset to Certified Sullair Repair Centers, and Precision Electric is the best source for Eaton SVX9000 drive repair. Precision Electric service technicians have hundreds of years combined experience in bench testing every component in Eaton SVX9000 drives, and replacement of failed electrical components on Eaton SVX9000 drives.

Precision Electric uses the most advanced testing equipment available in the industrial electrical world for testing Eaton SVX9000 drives, and Precision Electric replaces damaged components in Eaton SVX9000 drives with better components than the Original Equipment Manufacturer uses in their Eaton SVX9000 drives.

Call Precision Electric today for a free repair quote on your Eaton SVX9000 variable speed drive.

Variable Speed Drive Motors

Variable speed drive motors, also known as inverter-duty motors, are an asset in the industrial manufacturing world. When using a variable speed drive, variable speed drive motors are less likely to fail during production than general purpose motors. Variable speed drive motors exceed general purpose motors in performance, because variable speed drive motors are manufactured to operate at low speed (RPM) without overheating during production.

Variable speed drives generate high voltage spikes in all electric motors. Variable speed drive motors withstand the high voltage
spikes that are generated by variable speed drives, whereas general purpose motors do not. General purpose motors do not have the insulation required to withstand high voltage spikes, so the motor winding on a general purpose motor used with a variable speed drive begins to breakdown, and ultimately, the winding will burn up.

Variable speed drives used on electric motors that are 100hp (or greater) induce harmful voltage levels on the electric motor shaft. When harmful voltage levels exceed the resistance of the motor bearing lubricant, those voltage levels dissipate to the electric motor’s bearing housings. Harmful voltage levels sent to a motor’s bearing housings eventually leads to bearing failure in the electric motor. Variable speed drive motors use special bearings that are designed to withstand the harmful voltage levels that are induced by variable speed drives.

General purpose electric motors can be driven by variable speed drives, but once the general purpose motor fails, an inverter duty motor should replace the general purpose motor. Precision Electric recommends maintenance technicians who use general purpose motors on variable speed drive applications to keep a spare inverter-duty motor to minimize downtime.

Variable speed drive motors are more expensive than general purpose motors, but the increase in cost is worth preventing
downtime in variable speed drive applications when low speed is present. Many variable speed drive applications do not need to operate at low speeds, so variable speed drive motors are cost-prohibited in applications where low speed is not required.

Call Precision Electric for free quotes on variable speed drives, variable speed drive motors, servo motors, and all other industrial related equipment. Precision Electric offers free repair quotes on all industrial electronics equipment and industrial electronics field services.

Industrial Manufacturing Retrofit

Industrial Manufacturing RetrofitManufacturers tend to avoid original equipment manufacturers’ retrofit solutions, because original equipment manufacturers offer retrofits are cost-prohibited and time consuming. Once manufacturers’ equipment is not operating efficiently, maintenance technicians seek alternatives to maximize production. Maintenance technicians initially contact the original equipment manufacturer for solutions to speed up production lines in their manufacturing facilities. Once the original equipment manufacturer offers a retrofit package for their obsolete equipment, the maintenance technician usually cannot justify the retrofit cost and lead time. Fortunately, Precision Electric always offers an alternative solution to original equipment manufacturers’ retrofit packages. Precision Electric has been offering retrofit solutions to manufacturers since 1983. Precision Electric offers less expensive retrofit solutions that include system support, and an in service 12 month warranty.

Retrofit Alternatives

Manufacturers constantly seek new ideas to increase production, and Precision Electric provides retrofit alternatives to meet manufacturers’ production demands. Manufacturers usually do not have alternatives to original equipment manufacturers’ retrofit options, but Precision Electric offers alternatives to original equipment manufacturers’ expensive and uneconomical retrofits. Precision Electric redesigns obsolete equipment with a retrofit for industrial manufacturing facilities across the globe. Retrofitting production lines are a better alternative to purchasing original equipment manufacturers retrofit packages are are far less expensive, because most times original equipment manufacturers’ solutions are cost-prohibited, and obsolete.

Types of Variable Speed Drives

There are three general types of variable speed drives- DC Motor drives, Eddy Current Drives, and AC Motor drives. Each type of variable speed drive can be divided into different variations. Every variable speed drive system will include an electric motor and a speed control unit. Variable speed drive technology today mainly consists of solid state electronic components in a single system. Older variable speed drive systems used mechanical parts that over time, resulted in failure due to moving and worn parts.

DC Motor Drives

DC drives are also known as DC Motor Speed Control Systems. The speed of a DC motor is directly proportional to armature voltage and inversely proportional to motor flux; either armature voltage or field current can be used to control the motor speed. DC Motors have become expensive and today most dc motor speed control systems have been retrofitted with an AC motor and AC variable speed drive. AC variable speed drives are less expensive than DC systems, are more available and are more efficient than DC systems.

Eddy Current Motor Drives

An eddy current drive consists of a fixed speed motor and an eddy current clutch. The clutch contains a fixed speed rotor and an adjustable speed rotor separated by a small air gap. A direct current in a field coil produces a magnetic field that determines the torque transmitted from the input to the output rotor. The controller provides closed loop speed regulation by varying the clutch current, allowing the clutch to transmit enough torque to operate at the desired speed. Speed feedback is provided by an integral AC tachometer.

Eddy current drives are less efficient than other types of drives. Nearly all eddy current motor drive systems are obsolete today. There are few manufacturing facilities across the globe that still use eddy current motor drive systems, and when the equipment fails, it’s expensive to repair and often impossible to replace.

AC Motor Drives

AC variable speed drives are also known as, VSDs, variable frequency drives, VFDs, inverters, adjustable speed drives, and micro drives. AC variable frequency drives are used in many applications such as swimming pool pumps, air compressors, conveyor belts, lathes, mills, food processing production lines, waste water treatment pumps, HVAC fans and blowers, and many more applications in the industrial manufacturing world. Approximately one third of the world’s electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. This proves that significant energy efficiency improvement opportunities are available in the industrial manufacturing world if older DC motor speed control systems and eddy current drive systems are retrofitted with AC variable frequency drive systems.

Conclusion

Most manufacturers currently seek to replace their eddy current and DC variable speed drive systems with AC variable speed drive systems. Today, technology has reduced AC variable speed drive systems’ cost, physical size, and has improved performance through advances in semiconductor switching devices, simulation, control techniques, and control hardware and software. Manufacturers across the globe capitalize on AC variable speed drive technology to save money on their power bill, increase quality control, decrease production downtime, and improve overall efficiency in production lines.

Variable Frequency Drive Basics

Variable frequency drives are also known as (VFDs), variable speed drives (VSDs), adjustable speed drives, and inverters. Variable frequency drives are solid state controllers used in AC or DC electric motor applications. Most variable frequency drives are applied on alternating current (AC) electric motors in the industrial manufacturing world. There are some direct current (DC) electric motor applications that apply variable frequency drives, but most manufacturers seek AC motors because DC motors are expensive and often fail.  Variable frequency drives can also be used as a phase converters when three phase motors need to be operated from single phase power.

Variable frequency drives can be used in small appliances, large mills, lathes, air compressors, conveyors, and many other electric motor applications in the industrial manufacturing world. Over 30 percent of the world’s electrical energy is consumed by electric motors in fixed-speed fan, pump, and air compressor applications. The basic idea for using a variable frequency drive on mills, air compressors, and fans is to reduce the amount of electrical energy being consumed which consequently reduces electricity costs on unused power.

Energy Savings

About 3% of the total installed AC electric motors in the United States use variable frequency drives. An estimated 60-65% of electrical energy in the United States is used to supply electric motors, and 75% of that electrical energy is consumed by fan, pump and air compressor applications.

Approximately 18% of the electrical energy used in the 40 million motors in the United States could save power consumption via efficient energy improvement by using variable frequency drives on these electric motor applications.

Performance and Operation

Variable frequency drives are applied to alternating current (AC) electric motors to increase quality control in manufacturing processes in the industrial manufacturing world. Variable frequency drives increase quality control in the industrial manufacturing world via monitoring the electric motors’ speed, pressure, temperature, torque, and tension.

Fixed-speed electric motor loads subject the electric motor to a high starting torque and electrical current surges that are up to eight times the full-load motor current. When a variable frequency drive is used on an electric motor, the variable frequency drive gradually ramps the electric motor up to full load operating speed, and this decreases mechanical and electrical stress, which minimizes motor maintenance and motor repair costs which ultimately, extends the life of the electric motor and manufacturing equipment.

Variable frequency drives’ unique programming capabilities allow for application specific patterns to minimize electrical and mechanical stress on the electric motors’ they’re operating. Every variable frequency drive manufacturer uses a unique parameter selection designed so that every manufacturing facility can seek out the product designed for their industry.

Repair and Replacement

The internet has brought high demand of quality repair processes and competitive pricing in the industrial manufacturing world. Maintenance technicians began seeking alternative solutions via the internet for their need of variable frequency drive repair and replacement because maintenance technicians do not always receive the services needed to be a leader in their industry.

A highly trained repair facility is the backbone of successful production.  Precision Electric has been repairing industrial electronics, rewinding electric motors, and servicing all other industrial-related equipment since 1982. Customers on the coasts of the United States send Precision Electric repair work everyday such as variable frequency drives, servo motors, servo drives, encoders, printed circuit boards, electric motors, and all other related equipment.

Equipment repaired by Precision Electric is more reliable than brand new equipment purchased from the manufacturer, because Precision Electric uses the most advanced testing equipment and replaces generic components with the best components in the industry. Precision Electric offers an in-service warranty on all repair work completed. The Precision Electric in-service warranty begins the day repaired work is put into service and ends 12 months thereafter.

Variable Frequency Drive

A variable frequency drive is a solid state motor speed controller that is applied to alternating current (AC) electric motors. A variable frequency drive is also known as a VFD, inverter, variable speed drive, VSD, or a motor controller. Most pump, fan and air compressor applications use variable frequency drives to increase and decrease acceleration and deceleration time of an AC electric motor.

Increasing and decreasing acceleration and deceleration the start up time of an AC electric motor can also extend the lifespan of an electric motor. Using a variable frequency drive to increase or decrease the acceleration/deceleration time reduces voltage spikes that are generated into the winding of an electric motor. Reducing the voltage spikes that are generated into the winding of an electric motor prevents the motor winding insulation to breakdown and burn up.

Energy Savings

Approximately 60-65% of electrical energy in the United States of America is used to supply alternating current (AC) electric motors, and 75% of that electrical energy is consumed by fan, pump and air compressor applications. Only about 3% of the total installed alternating current (AC) electric motors in the United States of America run off variable frequency drives. A variable frequency drive can save energy costs up to 50% by reducing the AC electric motor speed (RPM) on applications where the full speed of the electric motor isn’t required.

Quality Control

Using a variable frequency drive in manufacturing processes can greatly increase quality control of end products and production times. A variable frequency drives special programming capabilities allow application specific patterns to minimize electrical and mechanical failure for the electric motors they’re operating. A variable frequency drive can also increase quality control in manufacturing production lines by monitoring the electric motors’ speed, heat (temperature), pressure, tension, torque, and many other technical factors. Every variable frequency drive manufacturer uses unique parameter programming designed for industry-specific applications.
