Abstract: The invention relates to an electromotor comprising a housing (5) which consists of a ferromagnetic material and a rotationally driven shaft (13) which is located in said housing (5). Said housing comprises at least one bearing shield (25), with a bearing (31) for the shaft (13). The bearing (31) has sensor means (33) for determining the state of rotation of the shaft (13). According to the invention, the bearing (31) is accommodated in a screening bushing (35) which is located in a bearing receiving opening (29) of the bearing shield (25) and which consists of a non-ferromagnetic material. A cover bushing (37) consisting of ferromagnetic material which is connected to the bearing shield (25) and which surrounds the shaft (13) is provided, and surrounds the bearing (31) and the screening bushing (35) on the inside of the housing.
