Electromagnetic clutch and brake device for generating and maintaining frictional connection, has magnetizable component, where coil is designed and arranged, such that magnetic field is generated with current feed of coil

摘要

The electromagnetic clutch and brake device has a magnetizable component (20) made of a material with magnetic remanence. A coil (26) is designed and arranged, such that a magnetic field is generated during energization of the coil. The magnetic field is sufficient for the magnetization of the magnetizable component. An independent claim is included for a method for operating an electromagnetic clutch and brake device.
