Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/016893
Kind Code:
A1
Abstract:
The present invention achieves a rotating electrical machine that can suppress torque ripple increases caused by division of a rotor core. This rotating electrical machine is provided with: an annular core back; a stator including a plurality of teeth, each of which protrudes in the radial direction from the core back and which are arrayed in the circumferential direction, with slots being formed between the teeth that are adjacent in the circumferential direction; and a rotor that includes an annular rotor core that is disposed rotatably and also coaxially with the stator with a magnetic gap therebetween, and a plurality of magnetic poles disposed on the rotor core in the circumferential direction. The rotor core includes a plurality of divided cores divided in the circumferential direction by division surfaces, and the number of divisions of the rotor core are different from a divisor or a multiple of the largest common denominator of the number of poles of the rotor and the number of slots.
