Title:
SYNCHRONOUS RELUCTANCE ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/088175
Kind Code:
A1
Abstract:
A synchronous reluctance rotary electric machine according to one embodiment of the present invention has: a shaft; and a rotor core. The shaft rotates about a rotation axis. The rotor core is fixed to the shaft, has formed therein four layers of cavities which project radially inward per single pole, and has bridges formed between the cavities and the outer peripheral surface. In a single pole, when the center in the peripheral direction is set as the pole center, both ends in the peripheral direction are set as pole ends, and the bridges are defined as a first-layer bridge, a second-layer bridge, a third-layer bridge, and a fourth-layer bridge in order from the pole center toward the pole ends; the width in the peripheral direction between the second-layer bridge and the third-layer bridge is set larger than that between the first-layer bridge and the second-layer bridge and that between the third-layer bridge and the fourth-layer bridge.
