Title:
ROTARY ELECTRIC MACHINE ROTOR
Document Type and Number:
WIPO Patent Application WO/2015/087126
Kind Code:
A3
Abstract:
A rotary electric machine rotor (10) includes a rotor core (20), a rotor shaft (30), and a nut portion (50). The rotor core (20) is made up of stacked thin magnetic plates. The rotor shaft (30) has, on one end side, a receiving portion (32) that abuts against one end surface in an axial direction of the rotor core (20), and has, on the other end side, an outer diameter threaded structure (40). The nut portion (50) meshes with the outer diameter threaded structure (40) of the rotor shaft (30). A position (28), on, the rotor shaft (30), of a contact surface between the nut portion (50) and the rotor core (20) is positioned farther to the other end side in the axial direction than the outer diameter threaded structure (40), when the rotor core (20) is fixed to the rotor shaft (30) by the nut portion (50) being fastened to the outer diameter threaded structure (40) of the rotor shaft (30).
