  "textContent": "A circuit arrangement is disclosed for supplying an electromagnetic holding brake (B) of an electric motor (M) with an operating voltage (UB) for releasing the holding brake (B), as well as with a voltage reduced compared to the operating voltage for holding the open holding brake (B). This circuit arrangement is distinguished from the prior art in that the operating voltage (UB) is supplied from a superordinate control unit (S) arranged separately from the motor (M) and holding brake (B), in that the circuit arrangement is arranged in or on the motor (M) or in or on the holding brake (B) and contains a voltage regulator which is configured to regulate the reduced voltage to a fixed value after the holding brake (B) is released, independent of the operating voltage (UB).",
