Abstract
A motor includes a magnet rotating together with a rotor about a central axis, a substrate on which a sensor to detect a position of the magnet is installed, a housing to hold a stator to drive the rotor, a bearing assembly including a bearing holder, and a conductor assembly between the housing and the bearing assembly. The conductor assembly includes a conductor including a first conductor electrically connected to the sensor through the substrate and a conductor holder covering the conductor. The substrate is fixed to the conductor holder. In the radial direction, a gap is located between an outer side surface of the bearing holder and an inner side surface of the conductor holder, and at least a portion of the magnet is located in the gap.
