    • A pump-motor unit of the type having an impeller connected to an armature and where the armature is separated from a stator by an air gap. The armature comprises a magnetic material having sufficient residual flux density whereby when the torque load on the impeller-armature structure is low, the magnet will act as a permanent magnet to provide synchronous rotation of the armature with respect to magnetic flux generated by the stator and when the torque load on the impeller-armature structure is high, will allow magnetic reversal whereby the armature will rotate asynchronously with respect to the magnetic flux generated by the stator.
    • 一种泵电机单元,其具有连接到电枢的叶轮,并且电枢通过气隙与定子分离。 电枢包括具有足够的剩余磁通密度的磁性材料,由此当叶轮 - 电枢结构上的转矩负载低时,磁体将用作永磁体,以提供电枢相对于由定子产生的磁通量的同步旋转,以及 当叶轮 - 电枢结构上的转矩负载高时,将允许磁性反转,由此电枢相对于由定子产生的磁通异步旋转。

    • A power plant, e.g. for an automotive vehicle, comprises a rotary heat exchanger and an engine mounted coaxially therewith on a stationary support, the engine having two relatively rotatable members (e.g. a turbine rotor and a turbine stator) driven in opposite directions by the vapor pressure of a working fluid passing in a closed circuit through an evaporator section of the heat exchanger, the engine housing, and a condenser section of the heat exchanger. One of the counterrotating members, generally the stator, is rigid with the housing whereas the other one is operatively coupled with a load, e.g. by magnetic flux traversing a magnetically pervious wall of the housing. The coupling may include an armature winding of an electric-current generator disposed outside the engine housing for excitation by one or more magnets carried by the rotor inside the housing. With a suitable step-down ratio between the load and the rotor, the latter may turn at a speed substantially higher than that of the stator.
