Technical FAQs 4

What is a motor inverter?

A motor inverter is an electronic device that converts direct current (DC) into alternating current (AC) to power an AC motor. It changes voltage and frequency, enabling the motor to run at variable speeds. While people often use inverter drive vs VFD interchangeably, the inverter stage is actually just one part of a complete VFD system.

How does an inverter control a motor?

An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.

How does an inverter work?

The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.

How do EV inverters work?

EV inverters do more than drive the motor — they also enable regenerative braking by reversing the power flow: Instead of pushing current to the motor, the inverter switches on slightly after rotor alignment, generating a drag torque. As the motor spins, it generates AC voltage.
