ABSTRACT:
Alternating-current, brushless, stator-controlled, asynchronous or synchronous-running, induction machines having a rotor with asymmetry in two axes electrically at right-angles, comprising two machine units coupled mechanically and electrically, to avoid the disadvantage of low-frequency currents in the mains supply experienced with single units. The coupled machine units are preferably combined in a single frame, providing right-angle electrical displacement between the two units. In one form, a single rotor is common to both stator elements. Asynchronous running is effected by extracting slip energy. Also synchronous running can be effected by d.c., as well as a.c., energizing of the stator windings. In neither mode of operation are connections to the rotor required.
