Patent attributes
The motor includes a cylindrical rotor core, a plurality of magnets axially penetrated in the rotor core, a pair of separation-preventing plates installed at both ends of the rotor core, and at least one fixing member to fix the separation-preventing plates to the rotor core. The fixing member includes a rod portion extending in an axial direction of the rotor core to be disposed on an outer circumferential surface of the rotor core, and supporting portions bent from both ends of the rod portion and used to support the separation-preventing plates. The separation-preventing plates can be fixed to the rotor core by the fixing member disposed on the outer circumferential surface of the rotor core. The fixing member has no risk of hindering the flow of magnetic flux generated from the magnets, resulting in an improvement in the performance of the motor.
