When electricity is applied to the field, It creates an internal magnetic flux. That flux is then transferred into a hysteresis disk passing through the field without the use of magnetic particles or friction components as there while the torque is very accurate and smooth, throughot the entire speed range.

The hysteresis effect in magnetism is applied to torque control by the use of two basic components-a reticulated pole structure and a specialty steel rotor/shaft assembly-fastened together but not in physical contact. Until the field coil is energized, the drag cup and shaft can spin freely on its bearings. When a magnetizing force from either a field coil or magnet is applied to the pole structure, the air gap becomes a flux field. The rotor is magnetically restrained, providing a braking action between the pole structure and rotor.
