Motor Controllers

Motor Controllers and Drives are electrical or electronic devices that regulate motor speed, torque, and position outputs. The drive modifies the power input to the motor to achieve the desired output. The controller circuits are commonly integrated with the drive circuits as one stand-alone unit, thus the terms motor drive and motor controller are frequently used interchangeably. There are four basic motor controller and drive types:  AC, DC, servo, and stepper, each having an input power type modified to the desired output function to match with an application.
