摘要： A slip ring is made of a carbonaceous material and a brush is made of a metal. A metal connection bar has an insert member held in the carbonaceous slip ring to make a mechanical and electrical connection without the necessity of an additional member. The slip ring and the connection bar are insert-molded in a slip-ring-support made of a resinous material. The slip-ring-support is press-fitted to a rear portion of the rotor so that the slip ring and the connection bar are fixed to the shaft at the same time. Further, the fan unit having a plurality of fan blades and a fan-supporting-portion is molded integrally with the slip-ring-support.

摘要： A vehicular generator motor performing generator operation and motor operation is disclosed. The generator motor comprises an AC-DC converter means and a switching means. The converter means is composed of a plurality of MOSFETs and connected between each armature coil and a vehicular storage battery. Alternating current produced across the coils is converted into a direct current for charging the battery by the AC-DC converter means in generator operation mode. In motor operation mode, the DC output from the battery is converted into an alternating current for setting up a rotating magnetic field by the converter means, and the battery output is fed to the armature coils. The mode of operation of the MOSFETs is switched between these two modes by the switching means. The rotating field produces a certain phase difference with the magnetic field developed by the rotating magnetic poles. The MOSFETs are made of SiC having a smaller resistivity than that of Si. This ensures a high withstand voltage necessary during power generation. Loss caused by large current flowing in the motor operation mode is reduced. Good driving torque can be obtained.
摘要翻译： 公开了一种执行发电机运行和电动机运行的车辆发电机。 发电机电动机包括AC-DC转换器装置和开关装置。 转换器装置由多个MOSFET构成，并连接在每个电枢线圈和车辆蓄电池之间。 在线圈中产生的交流电流被转换成用于通过AC-DC转换器装置在发电机运行模式下为电池充电的直流电流。 在电动机运转模式下，电池的直流输出转换为交流电，用于通过转换装置设置旋转磁场，电池输出被馈送到电枢线圈。 通过开关装置在这两种模式之间切换MOSFET的工作模式。 旋转磁场与由旋转磁极产生的磁场产生一定的相位差。 MOSFET的电阻率比Si的电阻率小，由SiC制成。 这确保在发电期间所需的高耐受电压。 电动机运转模式中流过的大电流引起的损耗减少。 可获得良好的驱动力矩。
