Document Type and Number:
WIPO Patent Application WO/2018/051631
Kind Code:
A1
Abstract:
Provided is a dynamo-electric machine for which assembly of a rotor core to a rotation shaft can be performed easily and efficiently. A rotor core 405 is configured by lamination of a first steel sheet body 421 comprising at least one electromagnetic steel sheet having a first projection 430a accommodated in a groove 451 in a rotating shaft 450, and a second steel sheet body 422 comprising at least one electromagnetic steel sheet having a second projection 430b accommodated in the groove 451 in the rotating shaft 450. The first projection 430a of the first steel sheet body 421 has a first locking part 431 deformed by a side surface 451a of the groove 451 in the rotating shaft 450, and at least a portion of the first locking part 431 of the first steel sheet body 421 is placed in a space 432 formed between the second projection 430b of the second steel sheet body 422 and the side surface 451a of the groove 451 of the rotating shaft 450.
