Abstract:
A motor includes a rotary assembly, a stationary assembly, and a bearing mechanism. The rotary assembly includes a resin portion that covers magnets and a rotor core. The rotor core includes a ring-shaped inner core portion, an outer core portion, and connecting portions that radially connect the core elements and the inner core portion. The resin portion includes an upper resin portion and a lower resin portion. The upper resin portion includes gate holes. The lower resin portion is located at a more radially inner side than the outer core elements, and includes a first core support mark exposing a portion of the bottom surface of the rotor core, and a second core support mark located in the outer core portion and exposing a portion of the bottom surface of the rotor core.
