Patent ID: 11909271

Abstract:
A rotating machine includes: an electric motor that includes a stator and a rotor that is rotatable relative to the stator; a rotary member to be rotated that is provided on the shaft; and a fastening member made of magnetic material and provided to fasten the rotary member to a shaft. The rotor includes: a rotor core made of magnetic material; a plurality of permanent magnets attached to the rotor core such that the permanent magnets are spaced from each other in a circumferential direction and magnetic poles of the permanent magnets that face an outer peripheral side of the rotor core in a radius direction of the rotor core have the same magnetic polarity; and the shaft. The shaft is made of magnetic material, provided to extend through a central part of the rotor core in an axial direction of the rotor core, and magnetized by part of magnetic fluxes generated from the permanent magnets.
