Abstract
A compact hydraulic supply unit has a housing forming a reservoir for a pressure fluid, and includes a housing bottom, a housing cover and a housing middle part therebetween in the form of a profiled tube. An electric motor has a laminated stator core held by the housing middle part, and drives a pump located at the housing bottom. The housing middle part has axially extending internal holding Webs for holding the laminated stator core. The size of the housing middle part is independent of the size of the electric motor, so that, with a low structural height, the housing can be so formed that it accepts a larger volume of pressure fluid.
