What is the difference between motor controller, motor drive, switch power supply?
Dc motor, directly connected to switch power source, the motor can certainly turn. But at this point, the motor's speed is uncontrollable. The motor controller, which can detect the rotating speed of the motor, and sends different electric power to the motor to make the motor stable. The operator can control the speed of the motor. The power of dc motor is very small, and the motor controller is limited, and it must be connected to "motor drive" to control different kinds of motors.
Switching power supply only provides dc power source, The controller USES electronic circuits to provide adjustable dc power. The actuator steps into the motor,
The switch power supply can only be powered by the power supply and cannot control it. The motor controller can control its rev., stop, counterturn and protect the motor. The motor drive can control its speed, travel, and turn.
