Document Type and Number:
Japanese Patent JP7031539
Kind Code:
B2
Abstract:
To provide a rotary electric machine capable of easily providing a magnetic part having a surface flux density distribution near to a sine wave.SOLUTION: A rotary electric machine comprises: a rotator 40 including a magnetic unit 1042 that contains a plurality of magnetic poles in which each polarity is alternated in a circumferential direction; and a stator 50. The magnet unit 1042 includes: a plurality of first magnets 1010 having a linear magnetization vector; and a plurality of second magnets 1020 having the linear magnetization vector. Each of the first magnets 1010 is arranged to the circumferential direction in a prescribed interval, and the plurality of second magnets 1020 is arranged at a position different from the adjacent first magnets 1010 in the circumferential direction. The magnetization vector in each first magnet 1010 is along a radial direction. The magnetization vector in each second magnet 1020 is near to the circumferential direction than the magnetization vector of each first magnet 1010.SELECTED DRAWING: Figure 26
