Another New Self-Excited Synchronous Induction Motor

One form of self-excited synchronous induction motor was described by the same author in a paper presented at the Spring Convention of the A. I. E. E., Birmingham, Ala., the present contribution describes a second form of such a motor. The starting, synchronizing, synchronous load and asynchronous overload periods are analyzed with special reference to the synchronizing torque, the automatic compounding and the weight efficiency, and it is shown that this second form is not only capable of duplicating the performance of the first form but of bettering same.
