    • A variable speed electromagnetic motor (69), generator or dynamic brake includes a rotor (52) and a stator (56), both mounted for rotation with respect to a reference element. A drive shaft is coupled to one of the rotor and the stator, and a controlled variable load is coupled to the other of the rotor and the stator. This variable load reacts against the reference element to apply a variable torque tending to retard rotation of the other of the rotor and the stator. In this way the speed of the drive shaft and the power transmitted by the drive shaft are controlled. Another variable speed electric motor, generator or dynamic brake includes a rotor having a rotor gear (74) and a stator having a stator gear (76). A gear or gear assembly (76) is coupled to the rotor gear in a manner to form a mechanical differential that causes the rotor and the stator to rotate in opposite directions, when the gear assembly is rotated.
    • 变速电磁马达(69),发电机或动力制动器包括转子(52)和定子(56),两者都安装成相对于参考元件旋转。 驱动轴联接到转子和定子中的一个,并且受控的可变负载联接到转子和定子中的另一个。 该可变负载与参考元件反应以施加倾向于阻止转子和定子中的另一个的旋转的可变转矩。 以这种方式,驱动轴的速度和由驱动轴传递的动力被控制。 另一变速电动机,发电机或动力制动器包括具有转子齿轮(74)和具有定子齿轮(76)的定子的转子。 一种齿轮或齿轮组件(76)以一种形成机械差速器的方式联接到转子齿轮,当齿轮组件旋转时,齿轮或齿轮组件(76)使得转子和定子沿相反方向旋转。
