Abstract
According to an embodiment, a resolver rotor includes: a resolver rotor core; and a resolver rotor core holder that constrains the resolver rotor core to a rotor shaft in a circumferential direction and an axial direction. The resolver rotor core holder includes: an annular flat plate portion; a first constraining portion that holds a relative position of the resolver rotor core holder to the rotor shaft, and holds an angle of the resolver rotor core in the circumferential direction relative to the rotor shaft; a second constraining portion that holds a relative position of the resolver rotor core holder to the rotor shaft; and a third constraining portion that holds a relative position of the resolver rotor core in the axial direction to the rotor shaft. The resolver rotor core includes a radially inside recessed portion for engagement with the first constraining portion.
