Servo Motor Controller

/in /by

A servo motor controller system is also known as a servo drive, servo amp, and a servo control system. A servo motor controller is an electronic device used to power and control a servo motor. A servo motor controller monitors and regulates the servo motor for precise speed regulation and positioning. Most manufacturers design servo motor controllers with a specific servo motor, so the servo motor cannot operate without the specific servo motor controller designed for said servo motor. Servo motor controller systems were designed as an alternative to AC and DC electric motors because industrial manufacturing facilities sought precise speed regulation and positioning in their industries, which AC and DC electric motors simply do not offer.Servo motor controller systems are mainly used in robotics, automation, and CNC applications.

What is a Servo Motor?

A servo motor is used for precise speed regulation in many different industrial manufacturing applications. Precise speed regulation is present in a servo motor by applying an encoder to the servo motor. The encoder on a servo motor provides speed feedback and positioning of the motor. The speed feedback and positioning loop generated by an encoder is designed to precisely control the exact position of the mechanics in a servo motor.

Variable Frequency Drive

/in /by

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 about3% 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.

Variable Frequency Drive Basics

/in /by

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.

Types of Variable Speed Drives

/in /by

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 currentdrive 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 thetorquetransmitted 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 thatsignificant 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.
