A brushless d.c. drive including a synchronous motor, including a multiphase armature winding, a switching device controlled by an electronic controller and connected upstream from the armature winding for commutation of the armature winding, and a device for generating a fail-silent response with simple circuitry measures and without any external components, and which includes a separating apparatus, arrangement or structure in the armature winding to respond in the event of a fault and separate the connections between the winding phases, including at the neutral point.
