Abstract
A motor includes a rotary shaft, a rotor fixed to the rotary shaft, a stator including a stator core surrounding the rotor in a radial direction about a center axis of the rotary shaft, and a coil wound on the stator core, a bearing supporting the rotary shaft, and a conducting member electrically connecting the stator core to an outer ring of the bearing. The rotor includes a facing portion formed of a bond magnet and facing the stator core in the radial direction, and an insulating joining portion joining the facing portion and the rotary shaft. A length L1 of the facing portion in an axial direction of the rotary shaft is equal to or shorter than a length L2 of the stator core in the axial direction.
