Elektromotorisch angetriebene Pumpe, insbesondere für die Servolenkung eines Kraftfahrzeuges

摘要

A pump driven by an electric motor, in particular for a motor vehicle power steering system, has a pump housing (3) which consists at least in one partial region (29) of a good heat-conducting material through which the pump medium flows, an electric motor (7, 9) arranged in or on the pump housing (3) and control electronics (5) arranged on or in the pump housing (3) for the electric motor (7, 9). For cooling purposes, one or more power semiconductors (31) of the control electronics (5) are brought into contact with the partial region (29) of the pump housing made of good heat-conducting material.
