The present invention relates to an electromagnetic motor comprising: an inner stator comprising a plurality of stator teeth, wherein each stator tooth is surrounded by one or more turns of electric wires; a controller that generates a set of currents applied to the phase windings of the inner stator to generate a pattern of magnetic poles spaced around the inner stator, wherein the spacing between the magnetic poles is greater than the spacing between adjacent stator teeth of the inner stator; an outer stator concentric with the inner stator and including a set of alternating magnetic poles,an interval between adjacent magnetic poles being smaller than an interval of the magnetic poles of the first array generated by the controller; and an intermediate rotor component located between thetwo stators and comprising an array of pole pieces wherein the pole pieces of the rotor shape the magnetic flux acting between the two stators, and whereby, in use, the controller is arranged to control the torque applied to the rotor by moving the magnetic pole pattern of the inner stator about the axis of the torque generator. The invention also relates to a steering wheel actuator assembly fora steer-by-wire steering system of a vehicle.
本发明涉及一种电磁马达,包括:内定子,其包括多个定子齿,每个定子齿由一匝或多匝电线包围;控制器,其产生一组电流,该电流施加到内定子的相绕组以产生围绕内定子间隔开的磁极的图案,所述磁极之间的间隔大于所述内定子的相邻定子齿之间的间隔;外定子,其与内定子同心并且包括一组交替的磁极,相邻磁极之间的间隔小于由控制器产生的第一阵列的磁极的间隔;以及中间转子部件,其位于两个定子之间并且包括极片阵列,其中,转子的极片成形在两个定子之间作用的磁通,并且由此在使用中,控制器布置成通过围绕扭矩发生器的轴线移动内定子的磁极图案来控制施加到转子的扭矩。本发明还涉及一种用于车辆的线控转向的转向系统的驾驶盘致动器组件。
