Abstract

296,488. Wist, E. June 8, 1927. Motor-generators.- Induction motors 14, 15 are controlled to run at various speeds by feeding them from an induction generator 7 driven from an induction motor 4, the frequency of the feed current being varied by varying the number of poles and reversing the rotating field of one or both machines. The motor 4 takes current from alternating supply mains which may be singlephase mains used in conjunction with a phasesplitting arrangement. A synchronous motor or generator may replace the machine 4 or 7 in certain cases.
