摘要 A motor rotor and a method for manufacturing a motor rotor, enabling the resolver rotor to be subjected to crimping which is a low cost operation and is less likely to affect the detection accuracy. A motor rotor (MR) is provided with a resolver rotor (RR) and with a rotor shaft (SH) to which the resolver rotor (RR) is affixed by crimping. The rotor shaft (SH) is provided with a first stepped section (SST) with which a crimping punch (JP) makes contact to deform the first stepped section (SST), a second stepped section (SHD) with which an end surface of the resolver rotor (RR) makes contact, and a cutout groove (SB1) formed in a surface which is located near the first stepped section (SST) and with which an inner peripheral hole section of the resolver rotor (RR) makes contact. In the crimping operation, the first stepped section (SST) of the rotor shaft (SH) is bent within the cutout groove (SB1) to form a crimping protrusion (SSD) which presses the end surface of the resolver rotor (RR).
