Abstract
A motor/pump assembly for a brake system includes at least one fluid pump arranged in a pump housing, an electric motor having a motor shaft configured to drive the fluid pump, a control unit arranged on the pump housing and configured to set a current rotational speed and/or a current torque of the motor, and a sensor arrangement having a measured value transmitter arranged within the pump housing and a magnetic measured value pickup stationarily arranged in the control unit. The control unit is further configured to detect contactlessly a current rotational angle of the shaft via the sensor arrangement, and to evaluate the angle to control the motor. The transmitter, in accordance with a rotary motion of the shaft, is configured to influence at least one magnetic variable of a magnetic field detected by the pickup.
