23KM-K(56□ 1.8°)

Stepping motors rotate at fixed angles with digitally controlled electronic pulses and they are able to start, stop and position with good control characteristics. Hybrid-type stepping motors consist of a rotor with permanent magnets and magnetic bodies, and by using ball bearings they can perform highly precise and reliable motions. Stepping motors can be used in wide range of applications, such as copy machines, multifunction printers, medical equipment, semiconductor manufacturing equipment, factory automation equipment, robots and other industrial equipment.
