The main structure of hysteresis brake is composed of rotor, inner pole and outer pole-fastened together but not in physical contact. Until the field coil is energized, the rotor can spin freely on the ball bearings. When a magnetizing force from a field coil is applied to the pole structure, the air gap becomes a flux filed. The rotor is magnetically restrained, providing a braking action between the pole structure and rotor.
