Abstract

The present invention sufficiently increases the torque of a rotating electric machine. A permanent magnet rotating electric machine 1 has a stator 10 and a rotor 20. The rotor 20 is provided with: arotor core 200; a plurality of permanent magnets 210 each fixed to the rotor core 200 such that at least a part of the outer circumferential surface thereof is exposed from the rotor core 200; and a magnet scattering prevention cover 265 for covering the plurality of permanent magnets 210. The cover 265 has magnetism.

Description

technical field [0001] The present invention relates to a rotor, a rotating electric machine using the rotor, and an electric auxiliary machine system for automobiles. Background technique [0002] In recent years, the trend of automobiles is to change from hydraulic systems to electric systems, and the market for hybrid vehicles and electric vehicles is also expanding, resulting in a rapid increase in the installation rate of electric power steering (hereinafter referred to as EPS) devices and electric braking devices . In addition, in the context of the spread of vehicles in which some of the driving operations such as idling stop and braking are automated, the improvement of driving comfort and the quietness of the interior of the vehicle are also progressing. At the same time, the demand for cost reduction is increasing. [0003] As the excitation source from the electric motor that causes vibration and noise in the vehicle interior, there are torque fluctuation compon...
