Variable Frequency Drives (VFD)
Variable Frequency Drives (VFD)
Perfect Automation offers a range of Variable Frequency Drives. A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A VFD is a specific type of adjustable-speed drive. VFDs are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives. VFDs are widely used. In ventilation systems for large buildings, variable-frequency motors on fans save energy by allowing the volume of air moved to match the system demand. They are also used on pumps, elevators, conveyors and machine tool drives. So as per application, a wide range of drives is available as per the response time, torque, highest peak current handling factor, etc. This becomes an extra skill to select appropriate drive as per application need. The company helps potential customers select the right drive to meet various requirements of different industries and accordingly program for optimum utilisation. Perfect Automation Systems deals in all types of automation products like AC drives, servo drives, PLC, energy monitoring systems, PID controller, encoders, flow meters, level transmitters, pressure/DP transmitter, liquid analysis systems and soft starters, and complete solutions for PLC automation.
