Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2022112961
Kind Code:
A
Abstract:
To improve the output of a rotary electric machine.SOLUTION: A permanent magnet 20 includes a first permanent magnet 21 and second permanent magnets 22 and 23. A first shaft member 30 has a first concave portion 33 that accommodates the second permanent magnet 22, and a second shaft member 40 has a second concave portion 43 that accommodates the second permanent magnet 23. Therefore, between the portions of the first end surface 140a of a stator core 14a located on both sides of the axis A1 of a cylindrical member 16, the magnetic flux passing through the cylindrical member 16 axially outside the first end surface 21a of the first permanent magnet 21 interlinks with the second permanent magnet 22. In addition, between the portions of the second end surface 141a of the stator core 14a located on both sides of the axis A1 of the cylindrical member 16, the magnetic flux passing through the cylindrical member 16 axially outside the second end surface 21b of the first permanent magnet 21 interlinks with the second permanent magnet 23.SELECTED DRAWING: Figure 2
