Abstract
A hydraulic power unit has a housing, at least one pump element, a pressure collecting plate and an electric motor. The electric motor has at least one end shield, a stator and a rotor fixed on a rotor shaft. The at least one end shield has at least one partially circumferential functional recess extending between an outer and an inner circumferential surface of the end shield in the direction of a rotor shaft bearing seat. The functional recess thus formed permits the arrangement of functional elements at a central point of the hydraulic power unit in a space-efficient manner without negatively influencing the overall size of the hydraulic power unit.
