Electro-mechanical brake device on an electric motor, in particular a low-power motor

摘要

The rotor brake of a low-power electric motor is ventilated by its own electromagnet (15) against the action of a spring (18), rather than as normal by the stray field of the motor. This results in reduced noise production, ventilation which is independent of the motor voltage, and more reliable braking thanks to the facility for using a stronger spring. <IMAGE>
