Stepper Motors Manufacturers

Stepper Motors are used in open loop control systems. The stepper motor rotates at fixed steps for every change in the driver signal. The typical step size of stepper motors is in range of 0.9 and 1.8 degrees. There are few types of stepper motors available such as bipolar permanent magnet stepper motor and unipolar permanent magnet stepper motor. Stepper motors are operated by applying current pulses of a specific frequency to the inputs of the motors. Stepper motors are capable of driving a 2.2-kw load with stepping rates from 1000 to 20,000 per second in angular increments from 180 degree down to 0.75 degree. The stepper motors are permanent magnet two-phase 12 V DC.
