AC Motor Repair

AC Motor Repair

/in /by

The first step in AC motor repair is identifying that there is a problem. If an electric motor smells like it’s burning, is vibrating and running loudly, or if the motor is not operating at its peak performance, something is probably wrong. When these circumstances present themselves, promptly shut the power off to the motor and machine to prevent further motor and machine damage. Once the power is off, it’s best to contact a trained professional with experience in AC motor repair.

AC motor repair cost always depends upon the extent of motor damage and availability of motor replacement parts. Repaircosts can be decreased by simple awareness that something is wrong. Contacting a motor professional is preferred to prevent injury. Motor professionals can also reduce unnecessary troubleshooting and downtime in the following ways: If the motor repair cost exceeds the replacement cost, an electric motor replacement motor can be shipped out right away. If the application is a DC electric motor, an electric motor professional can determine if replacing the DC equipment with AC equipment is a more economical choice. Often times a DC motor can be replaced with an AC motor, paired with an AC VFD. An AC motor paired with AC VFD has the ability to increase production,
decrease energy costs, reduce future repair costs, and offer other benefits.

AC motor repair can be decreased with preventative maintenance. Preventative maintenance tasks vary depending on the abilities and experience each motor shop offers. AC motor repair should only be performed by trained electrical technicians who have electric motorexperience. A lot of companies offering motor repair and preventative maintenance do not even perform these tasks; these companies outsource their jobs to a third party source, such as Precision Electric. To decrease costand increase turnaround time, ensure that whoever is offering the repair services, is actually performing the repair services.

VFD Drives For Dummies

VFD Drives For Dummies

/1 Comment/in /by

VFD Drives For Dummies: VFD is an abbreviation that stands for “variable frequency drives”. VFD Drives are also called “variable speed drives”, “adjustable speed drives”, “electric motor speed controllers”, and “inverters”. VFD Drives For Dummies: Every VFD hasits own component characteristics, so how each VFD works is dependent upon components within the VFD. Most VFD Drives for Dummies integrate a solid state electronics controller consisting of a bridge rectifier, a converter, and an inverter module.

Voltage-source inverter drives are the most common VFD Drives For Dummies. These drives convert AC line input to AC inverter output. There are some applications that use common DC bus and solar applications. These type of drives are configured as DC to AC drives. The bridge rectifier converter for volts per hertz drives is configured for 3 phase AC electric motors. The majority of variable frequency drives contain electronic circuitry that converts 60 Hertz Line power into direct current. The variable frequency drive converts this line power into a pulsed output voltage that duplicates varying alternating current to a desired frequency (speed). VFD drives were first introduced in 1983, and the insulated gate bipolar transistor has in the past 20 years become the standard for VFD drives as an inverter switching device.

VFD drives for dummies: Manufacturers will apply variable frequency drives to rotating equipment to reduce amperage spikes upon start up of large electric motors. Choosing the right VFD for an application will benefit rotating equipment by providing less wear on the electric motors where applied. Adjusting the acceleration and deceleration time of electric motors can extend the lifespan of an electric motor. Variable frequency drives provide the ability to control the frequency of starting and stopping of an AC electric motor. This ability allows an AC electric motor to only operate when needed for the equipment its rotating, and electric motors have a longer lifespan if they are only running when they need to be.

Approximately one third of the worlds electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. These fixed-speed applications hardly ever require the full load speed (RPM) of the electric motor in which theyre operating. By installing a VFD to these applications, electric motor speeds are reduced, and power costs can be reduced by 50% or more. Technology has allowed cost and physical size reduction of variable frequency drives, and has improved performance through advances in technology.

Properlypaired VFD drives with the correct electric motor will significantly reduce operating costs for manufacturers. This is particularly true for variable torque loads such as fans, blowers, and pumps. Blowers are often used with dampers to control air flow; these dampers may operate either manually or automatically. When dampers are closed, 50% of the electric motor current will drop to approximately 60% of full load nameplate current. By utilizing variable frequency drives in blower applications, the current draw of the motor will be reduced 30% for every 10% drop in speed. The same electric motor operating from an AC variable frequency drive at 50% speed, will draw approximately 20% of the full load current.

Allen Bradley servo motor repair is less expensive than Allen Bradley servo motor replacement. Trained technicians should perform Allen Bradley servo motor repair. Technicians undergo unique testing procedures on Allen Bradley servo motors that are dependent upon their model, features, operations, and prints. Allen Bradley servo motor repair should initially be inspected for cosmetic damage. Taking photos of the servo motor prior to further processing is suggested.

Servo Motor nameplate data and preventative maintenance info should be collected by the repair technician and safely stored for future reference. Once these initial steps are complete, the servo motor should be meter tested before test running on a control panel; Meter testing prevents further damage to parts, winding, and insulation. The servo motor should then beconnected to a test stand to check EMF (electromagnetic frequency), encoder or resolver feedback, and commutation alignment; These standard tests are to ensure functionality oncethe motor is installed forproduction. Servo motors also need to be tested with an oscilloscope to create an operation print. Once an operation printout is generated, a technicianwill check for connection issues, magnet failure, winding failure, and perform a 100% component test.

Once the technician finishes making repairs, they will then reassemble for final testing. During the final test procedure, technicians should connect the motor to an inverterwith and without a load. Running the servo motor on an inverter is to ensure complete functionality. Testing with an inverter also allows verification that the servo can operate at full voltage and withstand full load amps of motor specifications. Repair shops should work closely with all servo motor manufacturers. Working closely with servo motor manufacturers allows for access to servo motor data sheets. Repair technicians use data sheets to ensure that the servo motor performs equal to, orbetter than, the original manufacturer standards.

Most repair shops offering Allen Bradley servo motor repair do not even perform the repair in their facility. Instead, these repair shops outsource the repair to a third party such as Precision Electric. Using a third party repair shop is risky, more expensive, and has a longer lead time than going directly to the repair source.Allen Bradley servo motor repair from Precision Electric includes a 12 month in-service warranty.
