The invention relates to an electric motor for use in a steering assembly of a vehicle, said motor comprising a stator with a plurality of phase windings and a rotor with a plurality of magnetic poles and connected to a shaft; the stator comprises a yoke having a plurality of teeth, each tooth comprising a stem and a tooth tip located at an end of the stem closest to the rotor, and the motor further comprises a sleeve of electrically conductive material located in a position that is otherwise an air gap between the inwardly facing tip of the stator tooth and the rotor, and wherein the sleeve is configured to be electrically conductive with respect to the stator. The sleeve includes an electrically conductive material that provides a magnetic flux path that extends axially along the motor bore such that rotation of the rotor generates an eddy current within the sleeve that resists rotation of the rotor. The invention also relates to a steering wheel actuator assembly of a steer-by-wire vehicle.
本发明涉及一种在车辆的转向组件中使用的电动马达,所述马达包括定子和转子,所述定子带有多个相绕组,并且所述转子带有多个磁极并且与轴连接;并且所述定子包括具有多个齿的轭,每个齿包括干部和齿尖部,所述齿尖部位于干部的最靠近转子的端部处,并且所述马达还包括导电材料的套筒,所述套筒位于否则为定子齿的面向内部的尖部与转子之间的气隙的位置中,并且其中,所述套筒包括导电材料,所述导电材料提供沿着马达孔轴向延伸的磁通路径,使得转子的旋转在套筒内产生涡电流,所述涡电流抵抗转子的旋转。本发明还涉及一种线控转向车辆的驾驶盘执行器组件。
