ABSTRACT:
Winding arrangement of a stator and/or rotor of a three-phase generator or electromotor makes possible an improvement of all performances of these electric machines. The improvement is obtained in that to star-connected windings there are connected additional delta-connected windings, which in relation to the star-connected windings are spatially shifted for an angle of (.pi./2p).+-.(.pi./6p), p being the number of pole pairs. Such a winding arrangement is symbolically expressed by Y+j.DELTA.= .
