ROTATING ELECTRICAL MACHINE

WIPO Patent Application WO/2018/052033

A1

A rotating electrical machine 20 comprising a stator 22 and a rotor 24. The stator 22 has a stator core 40 and an armature winding 42 wound around the stator core 40. The rotor 24 has a field core 50, a field winding 52, and a cylindrical short circuit member 54 and is arranged facing the inner circumferential side of the stator, in the radial direction. The field core has a cylindrical boss section 58 and a plurality of hook-shaped magnetic pole sections 62 arranged on the outer circumferential side of the boss section and having magnetic poles having alternating polarity in the circumferential direction formed therein. The field winding is wound on the outer circumferential side of the boss section. The short circuit member is arranged so as to cover the outer circumferential surface of the hook-shaped magnetic pole sections, on the outer circumferential side of the hook-shaped magnetic pole sections, and magnetically connects hook-shaped magnetic pole sections that are adjacent in the circumferential direction. The surface of the short-circuit member facing the stator is formed in an uneven shape having protrusions 80 that protrude in the radial direction and groove sections 82 that are recessed in the radial direction, arranged alternately and continuously thereupon.
