Title:
MAGNET FIXING STRUCTURE
Document Type and Number:
Japanese Patent JP2023122303
Kind Code:
A
Abstract:
To provide a magnet fixing structure for detecting a rotation speed of a rotary shaft so as to improve reliability of a rotary electric machine.SOLUTION: A magnet fixing structure comprises: an annular fixing member 41 which is mounted to a rotary shaft 3 of a rotary electric machine; and at least one magnet 42, which is mounted to the fixing member 41, for detecting a rotation speed of the rotary shaft 3. The fixing member 41 includes: a cylindrical part 41A extrapolated over an entire circumference of the rotary shaft 3; and a magnet fixing part 41B for fixing the magnet 42 at an outer peripheral position of the cylindrical part 41A. At least one hole 41Ca is provided between the magnet fixing part 41B and the cylindrical part 41A in the fixing member 41 in a view in a direction along the rotary shaft 3.SELECTED DRAWING: Figure 5
