Document Type and Number:
WIPO Patent Application WO/2014/156158
Kind Code:
A1
Abstract:
A synchronous reluctance motor (100) comprises: a shaft (23); a rotor core (21) fixed to the shaft (23), and having a plurality of flux barriers formed therein; a stator core (11) having a plurality of protruding stator teeth formed therein; and a multiphase armature winding (15) wound around the plurality of the stator teeth (12). The flux barriers include: a plurality of first flux barriers (41) formed spaced apart in the circumferential direction, and extending in the radial direction; and a plurality of second flux barriers (31) formed mutually spaced apart in the circumferential direction, and having a curved surface protruding toward the center of the rotary shaft in each circumferentially angular region sandwiched by the first flux barriers (41).
