Technical FAQs 4

What is an AC motor inverter?

Understanding these differences can help in making more informed decisions when selecting and designing motor systems. The primary function of an AC motor inverter is to convert DC power into AC power. It controls the speed and torque of an AC motor by adjusting the output frequency and voltage.

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.

What is the difference between AC motor inverter and motor controller?

In contrast to AC motor inverters, motor controllers have a broader range of functions. They include not only speed control but also position control, torque control, and other types of control. Motor controllers calculate appropriate motor control signals based on input and feedback signals to meet specific motion control requirements.
