An inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor. What are Inverter Drives? Reviewed by Stephen Bettles, Technical Support Engineer (September, 2024) Inverter drives, also known as variable frequency. . Motor inverter is an electric energy conversion device, its role is to convert direct current energy into AC electrical energy to control the speed and torque of the AC motor. You would not be able to control the speed, making the applications for the motor. . An inverter takes DC electricity from the EV battery and transforms it into three-phase AC electricity. Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter or VFD. This blog post also introduces another option.
