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 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.
