Document Type and Number:
Japanese Patent JP6681301
Kind Code:
B2
Abstract:
A circuit arrangement is configured to supply an electromagnetic holding brake of an electric motor with an operating voltage for releasing the holding brake, and a voltage that is reduced relative to the operating voltage for holding the holding brake in the released position. The operating voltage is supplied from a higher-level control system disposed separately from the motor and the holding brake. The circuit arrangement is disposed in or on the motor or in or on the holding brake and includes a voltage regulator adapted to regulate, independently of the operating voltage, the reduced voltage to a fixed value after the holding brake is released.
