This is an electronic device used to help control the speed of an AC motor
. If you take a closer look at the induction motor, it is constructed usinga rotor with windings that intersect the rotating magnetic field from the rotorwindings. When operating at full speed, the rotor runs slower than the motor.This is caused by the magnetic field that makes current to flow into the rotorwindings resulting in lower torque. Now, the AC Variable Frequency Drive
isused to control the speed of the drive. The AC VariableFrequency Drive operates by turning the power lines into the frequency that isneeded to harmonize the frequency of the drive and rotor. The drive iscontrolled by a microprocessor that monitors the incoming voltage supply, DClink voltage, and incoming voltage supply. It also checks the overall outputand current to ensure that the motor is operating within the recommended levels.Using the AC Variable Frequency Drive is very important if youwant to increase the efficiency of your motor. It also increases its lifespan andreduces the overall power consumption. When you get the right AC VariableFrequency Drive, it helps to reduce damages and cut associated costs. Rememberto ensure that only the right AC Variable Frequency Drive is selected dependingon your motor.
