SYNCHRONOUS RELUCTANCE TYPE ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/074561
Kind Code:
A1
Abstract:
A synchronous reluctance type rotating electrical machine according to a mode of embodiment of the present invention includes a shaft, a rotor iron core, rotor iron core retainers, a plurality of conductor bars, and short circuit rings. The shaft rotates around an axis of rotation. The rotor iron core is fixed to the shaft, and void portions having a convex shape facing toward the radially inner side are formed in a plurality of layers for each pole. The rotor iron core retainers retain the rotor iron core by pressing the same from both sides in the direction of the axis of rotation. The plurality of conductor bars are disposed in the void portions, extending in the axis of rotation, and the two ends thereof project through the rotor iron core retainers. The short circuit rings are provided at both ends of the plurality of conductor bars, and link the plurality of conductor bars. Further, the conductor bars are fixed to the rotor iron core retainers.
