Abstract

A rotor assembly of a rotating electrical machine capable of obtaining an excellent effect of reducing torque ripple with a simple structure. A rotor assembly (16) of a rotating electric machine (11) is a first rotor unit (17) and a second rotor unit (19) provided with a magnetic pole portion (33) of a magnet (31) for a common magnetic field arranged side by side in the axial direction It is composed of multiple axially combined. A first groove portion (37) extending in the axial direction is provided on an outer peripheral surface (35) of the first rotor unit (17). On the outer peripheral surface (35) of the second rotor unit (19), there is provided a second groove portion (39) extending in the axial direction, and the second groove portion (39) is different from the first groove portion (37) in the circumferential direction. Overlapping dislocation arrangement. The first magnetic pole center (40) of the magnetic pole portion (33) possessed by the first rotor unit (17) is positioned relative to the second magnetic pole center (42) of the magnetic pole portion (33) possessed by the second rotor unit (19). d axis symmetric position.

Description

technical field [0001] The present invention relates to a rotor assembly and a rotating electric machine capable of reducing torque ripple. Background technique [0002] In recent years, as an effort to realize a low-carbon society, vehicles equipped with a rotating electrical machine in addition to an internal combustion engine as a driving source of the vehicle or equipped with a rotating electrical machine instead of the internal combustion engine as a driving source of the vehicle have become popular. Vehicles called hybrid electric vehicles (Hybrid Electric Vehicles) and electric vehicles (Electric Vehicles) are vehicles as described above. [0003] The rotating electric mechanism includes an annular stator and a cylindrical rotor. The stator is configured such that a stator coil is provided in each of a plurality of slots included in the stator core. The rotor is separated from the inner peripheral surface of the stator with a slight gap, and is set to rotate freely....
