How does a motor controller work?

How does a motor speed controller work? All 4QD controllers work by switching the battery connection to the motor on and off around 20,000 times a second using a technique called pulse width modulation [PWM]. … The motor averages these pulses out, as this rate of switching is too fast for the motor to detect.

Why do you need a motor controller?

A Motor Controller is a device that acts as intermediary between your robot’s microcontroller, batteries and motors. A motor controller is necessary because a microcontroller can usually only provide roughly 0.1 Amps of current whereas most actuators (DC motors, DC gear motors, servo motors etc.) require several Amps.

How does current controller work?

Simply put, a DC motor controller is any device that can manipulate the position, speed, or torque of a DC-powered motor. … Also, unlike some AC motors, DC motors are easily reversed by simply switching their leads so that the DC current runs in the opposite direction.
