摘要： Disclosed in the present invention is a shaft construction for motor-generators and alternators that provides effective airflow and improved overall cooling without the need for an external fan. The shaft comprises a plurality of circumferentially disposed centrifugal fan blades and longitudinal cooling channels. As the shaft rotates, the centrifugal fan blades pull the air inwardly across the winding end-turns on one end of the stator into the housing and propels the w at high pressure through the cooling channels along the shaft to cool the rotor diner circumferential surfaces, winding end-turns on the other end of the stator and bearings mounting surfaces, and exhausts through the exhaust vents on the ends of the housing. The airflow path provides effective cooling of the stator windings, rotor, shaft and bearings that prevents high temperature gradients, thus resulting in improved motor-generator performance.
摘要翻译：在本发明中公开了一种用于电动发电机和交流发电机的轴结构，其提供有效的气流和改进的总体冷却，而不需要外部风扇。轴包括多个周向设置的离心风扇叶片和纵向冷却通道。当轴旋转时，离心风扇叶片将空气向内拉过定子一端的卷绕端匝到壳体中，并且通过沿着轴的冷却通道将w推向高压，以冷却转子餐台周向表面，在定子和轴承安装表面的另一端上缠绕端头，并通过壳体端部上的排气口进行排气。气流路径可有效冷却定子绕组，转子，轴和轴承，防止高温梯度，从而导致电机发电机性能的改善。

摘要： Disclosed in the present invention is a dual-structured power output apparatus of an electric drive and power system that provides a means for outputting both mechanical power and electrical power. It comprises dual motor/generators having two stator assemblies, two rotor assemblies and a power transmission unit all integrated into a single housing for easy mounting. The power transmission unit is disposed adjacent to the two motor/generators and coupled on both ends to rotating shafts mechanically linked to the rotor assemblies such that they are rotatable relative to each other. It function is to change the rotational speed and torque of at least one of the rotors in order to reduce weight and physical size of the apparatus, and thus significantly improving the power density and capability. The structure of the apparatus is well-suited to improve the performance and fuel efficiency of the prior art hybrid powertrain.

摘要： Disclosed in the present invention is a tandem starter-generator construction that includes an induction motor-generator, a permanent magnet motor-generator and power transmission unit disposed adjacent to the motor-generators. The induction motor-generator is utilized predominantly as a motor to provide mechanical power at relatively high efficiency as a motor, and as a generator to provide electrical power during regenerative braking. The permanent magnet motor-generator is used predominantly as a generator for very high efficiency power conversion and to capture additional electrical power during regenerative braking to compensates for the regenerative energy captured at lower efficiency by the induction motor-generator. Accordingly, the tandem motor-generator construction disclosed herein overcomes the drawbacks of low efficiency of an induction motor-generator operating in regenerative mode and a permanent magnet motor-generator magnetic drag losses during periods of non-utilization at high speeds in order to improve fuel efficiency of a parallel hybrid vehicle.
