本文研究的是一种新型高速交流电动机的研制。该电机在结构上是磁性三联器与交流电机的磁性组合。我们称之为“混合动力发动机”。当仅应用60Hz的商业源时，电机可以旋转近10,800rpm。我们总结的结果如下：(1)高速混合单相电动机：该电动机是由遮阳线圈式感应电动机和磁性三联器组合而成。应用单相商用电源可以使转速接近10,800rpm。电机没有半导体器件。电动机的转矩-转速特性与传统的单相感应电动机相似。测试电机的最大扭矩为1.0kgcm。但是电机有一些问题，那就是起动转矩。电机的容量，功率因数和效率。(2)高速混合式两相电动机：该电动机由旋转磁场型感应电动机和两相磁力三联器组合而成。与混合单相电机相比，该电机可以提高启动转矩和效率。测试电机最大输出功率158W，效率12.5%，功率/重量比14W/kg。(3)高速混合式同步电动机电动机的结构为两相磁三联器和磁阻电动机的组合。同步转速为10.800rpm。测试电机的最大扭矩为1.5kgcm。

The research deals with the development of a new type high-speed AC motor. The motor has the magnetic combination of the magnetic tripler and the AC motor in structure. We call it "hybrid motor". When only a commercial source at 60Hz is applied, motor can rotate near 10,800rpm.We have summarized the results as follows,(1) High-speed hybrid single-phase motorThe motor has the combination of the shading-coil type induction motor and a magnetic tripler. The application of a single-phase commercial source enables the rotation near 10,800rpm. The motor has no semiconductor device. The torque-speed characteristics of the motor is similar to that of a conventional single-phase induction motor. The maximum torque is 1.0kgcm on the tested motor. But the motor has some problems, that is, starting torque. capacity of the motor, power factor and efficiency.(2) High-speed hybrid two-phase motorThe motor has the combination of the rotating-field type induction motor and a two-phase magnetic tripler which two proposed. The motor can improve the starting torque and the efficiency compared with the the hybrid single-phase motor. The tested motor has the maximum output power 158W, efficiency 12.5% and the power/weight ratio 14W/kg.(3) High-speed hybrid synchronous motorThe structure of the motor is the combination of the two-phase magnetic tripler and a reluctance motor. The synchronous speed is 10.800rpm. The maximum torque is 1.5kgcm on the tested motor.
