ROTOR UND HERSTELLUNGSVERFAHREN

摘要

A rotor includes a rotor core, a permanent magnet inserted into an opening formed along a circumferential direction of the rotor core, and end plates provided to sandwich the rotor core in a direction of a rotation axis. The permanent magnet is fixed to the rotor core with an adhesive. A stainless steel plate is provided between the rotor core and each of the end plates, the stainless steel plate having a linear expansion coefficient falling between that of the rotor core and that of the end plates. An outer periphery of each of the end plates in a circumferential direction has a portion placed to be radially inward with respect to an outer periphery of the stainless steel plate.
