    • This invention is a rotating electrical machine comprising two major components capable of relative rotation about a common axis and separated by an air gap in which magnetic fields linking the two main components through the air gap act both to exert torque and lateral forces. A set of windings is present on at least one of these components and this set of winding is used to generate a distribution of flux having two parts: the first part serving primarily to case torque and the second part serving to cause a net lateral force between the two main components. This machine uses the physical connection of the coils within the phases of the machine such that separate sources can be used for supplying currents for generating torque and lateral forces independently. The voltage and current ratings of the supply used for generating the lateral forces can both be substantially lower than the corresponding ratings of the supply used for generating the torque.
    • 本发明是一种旋转电机,其包括两个主要部件,能够相对于公共轴线相对旋转并由气隙分开,其中通过气隙连接两个主要部件的磁场用于施加扭矩和横向力。 一组绕组存在于这些部件中的至少一个上,并且该组绕组用于产生具有两部分的焊剂的分布:第一部分主要用于壳体扭矩,第二部分用于在第二部分之间产生净侧向力 两个主要组成部分。 该机器在机器的相位内使用线圈的物理连接,使得可以使用单独的源来独立地产生用于产生转矩和横向力的电流。 用于产生横向力的电源的电压和电流额定值都可以大大低于用于产生转矩的电源的相应额定值。
