Document Type and Number:
Japanese Patent JP7259653
Kind Code:
B2
Abstract:
To provide a rotor capable of suppressing a decrease in torque of a rotary electric machine and obtaining a high strength of a holding ring.SOLUTION: A rotor of a rotary electric machine includes: a plurality of permanent magnets placed on an outer peripheral surface of a rotor shaft; a holding ring that is fitted to the outer peripheral side of the permanent magnet and fixes the permanent magnet to the outer peripheral surface of the rotor shaft; and a ring guide portion provided adjacent to the arrangement region of the permanent magnet in an axial direction of the rotor shaft and having a tapered surface whose diameter is reduced toward a direction away from the first end facing the permanent magnet. The holding ring is formed by laminating magnetic metal plates by surface bonding along the axial direction.SELECTED DRAWING: Figure 1
