What is a motor controller and what does it do

A motor controller is a device that regulates the operation of an electric motor, including its speed, torque, and direction.

What is the difference between AC and DC motor controllers?

AC motor controllers manage motors that use alternating current, while DC motor controllers are designed for motors powered by direct current. AC controllers often use variable frequency drives, while DC controllers manage current flow with H-bridges.

How does a motor controller affect speed and torque?

Motor controllers regulate the power supply to the motor, controlling its speed by adjusting voltage or frequency and managing torque through current regulation.
