You can get NEMA series stepper motor in various configurations and its corresponding accessories. It is a brushless DC motor, so the life of this motor is dependent upon the life of the bearings. The position control is achieved by a simple Open Loop control mechanism so it doesn’t require complex electronic control circuitry.
The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control. Stepper Motor provides excellent response to starting, stopping, and reversing pulses from the stepper motor driver.
