Abstract
A motor-pump system includes a first housing part, a hydraulic pump, an electric motor, and a sensor board. The hydraulic pump includes an outer gerotor rotationally supported on the first housing part and an inner gerotor rotationally supported on the first housing part. The electric motor includes a stator assembly rotationally fixed in the first housing part and a rotor assembly with a non-ferrous sensor target, fixed to the outer gerotor. The sensor board includes a plurality of sensor traces for inductively sensing a signal from the non-ferrous sensor target when the outer gerotor is rotated.
