| Zusammenfassung: | An electric motor includes a stator; and a rotor disposed so as to be rotatable with respect to the stator, wherein the rotor includes: a rotor core having a plurality of poles and slots; a shaft coupled to a central portion of the rotor core; a rotor coil wound on the rotor core; and coil supporting members provided at the rotor core, and configured to support the rotor coil such that the rotor coil is prevented from being separated from the rotor core in a radial direction when the rotor rotates. Under such configuration, a short-circuit of the rotor coil due to a centrifugal force when the rotor rotates, can be prevented. |
