Title:
ROTOR OF ROTARY ELECTRIC MACHINE, AND METHOD FOR MANUFACTURING ROTOR
Document Type and Number:
Japanese Patent JP2023110652
Kind Code:
A
Abstract:
To suitably hold a permanent magnet in a fixed state in a magnet storage hole.SOLUTION: A rotor 12 includes a rotor core 21, and a permanent magnet 22 stored in a plurality of magnet storage holes 24 provided on the rotor core 12. The magnet storage holes 24 are provided in a direction extending in a circumferential direction in the rotor core 21, and the permanent magnet 22 is fixed into the magnet storage holes 24 using a resin 28. The permanent magnet 22 is stored in the state where the resin 28 is interposed between an outer peripheral side core surface 25a as a core wall surface on the outer peripheral side in the magnet storage hole 24 and the permanent magnet 22, and between an inner peripheral side core surface 25b as a core wall surface on the inner peripheral side and the permanent magnet 22. The adhesive force of the resin 28 on the side of the outer peripheral side core surface is made to be higher than the adhesive force of the resin 28 on the side of the inner peripheral side core surface.SELECTED DRAWING: Figure 3
