摘要:
The motor comprises a rotary unit, a stationary unit disposed around the rotary unit, and a bearing mechanism. The rotary unit comprises a plurality of magnets, a rotor core, a resin portion which covers the plurality of magnets and the rotor core. The rotor core comprises a ring-shaped inner core portion disposed at a radially inner side of the plurality of magnets, an outer core portion, and a plurality of connecting portions which radially connects the plurality of core elements, which are disposed between the plurality of magnets, and the inner core portion. The resin portion comprises an upper resin portion and a lower resin portion. The upper resin portion includes a plurality of gate holes. The lower resin portion is disposed at a more radially inner side than the plurality of outer core elements, and further comprises a first core support mark which exposes a part of the bottom surface of the rotor core, and a second core support mark disposed in the outer core part, and exposes a part of the bottom surface of the rotor core.
