  • Electromotive drive system for use with a pump of a power-assisted steering system in a motor vehicle
    Patent number: 7015605
    Abstract: An electromotive drive is provided, especially for the pump of a power-assisted steering system of a motor vehicle. The drive includes a housing (3) with a bearing journal (15) in which the shaft (18) of a rotor (9) is rotationally mounted. The drive also includes a stator (7) having drive windings. The bearing journal (15) extends through said stator and supports it. The stator (7) is supported by the bearing journal (15), substantially in the transversal direction only. The stator (7) is coupled with the remaining housing (3) in a rotationally fixed manner, so as to transmit the engine torque. The arrangement dramatically reduces disturbing noises which occur especially when the motor is operated at full load and which are caused by relatively high-frequency torque variations.
