摘要:
The present invention relates to a doubly salient permanent magnet electric machine that has a winding structure in which series-connected windings are included in the phase windings of a mover, and that has a stator implemented as an iron core having a plurality of permanent magnets and a plurality of stator salient poles neighboring the permanent magnets, thus reducing the number of permanent magnets by half. An electric machine is configured such that a mover moves while facing a stator and includes an N (a number of power phases) multiple number of teeth and phase windings wound around the teeth, and one or more pairs of phase windings of the mover mutually having a phase difference of 180° are connected in series, and the stator includes permanent magnets in depressions between individual stator salient poles of an iron core in which the stator salient poles are formed.
