Title:
ROTARY ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/168896
Kind Code:
A1
Abstract:
A stator (840) of a rotary electrical machine (80) is unrotatably fixed to a housing (830). A shaft (870) is rotatably supported by the housing (830). A rotor (30) has a rotor core (31, 32) and a plurality of stages of magnets (33, 34) provided on a radially outer side of the rotor core (31, 32) by being shifted in the circumferential direction according to the skew angle, and rotates integrally with the shaft (870). A rotor cover (40) has a first large-diameter portion (41) provided on one end side in the axial direction, a second large-diameter portion (42) provided on another end side in the axial direction, and a small-diameter portion (45) provided between the first large-diameter portion (41) and the second large-diameter portion (42) and having a smaller diameter than the first large-diameter portion (41) and the second large-diameter portion (42) at an intermediate portion of magnets (33, 34) that are adjacent in the axial direction, the rotor cover (40) being press-fitted and fixed to a radially outer side of the rotor (30).
