Patent ID: 10277101

Abstract:
A rotor includes a rotor core formed by laminating steel sheets, first and second plate members respectively arranged on first and second axial sides of the rotor core, first short-circuiting pins held by the first plate member and having been inserted in respective pin-receiving holes of the rotor core from the first axial side, and second short-circuiting pins held by the second plate member and having been inserted in respective pin-receiving holes of the rotor core from the second axial side. One of the first short-circuiting pins and one of the second short-circuiting pins respectively function as first and second positioning pins. For at least one of first and second positioning pin-receiving holes in which the first and second positioning pins are respectively received, each of the steel sheets forming the rotor core has a chamfered or curved corner around the positioning pin-receiving hole on a positioning pin insertion side.
