Abstract: A motor and a fan device are provided. The motor includes a motor bracket; a conductive shaft fixed to a front surface side of the motor bracket; a rotor rotatably supported on the shaft; a stator fixed to the front surface side of the motor bracket inside the rotor and wound with a plurality of coils for generating a magnetic field to rotate the rotor; a substrate, a front surface thereof mounted with a driver circuit for controlling magnetic field generation by the coils; and a driver case fixed to a rear surface side of the motor bracket and forming an accommodation space accommodating the substrate between itself and the motor bracket. A positive wiring of the driver circuit is mounted outside a region on the substrate overlapping the shaft when the motor is viewed from an axial direction of the shaft.

Abstract: A brushless motor includes a motor body, a bracket, and a power supply structure for supplying power to the motor body through a through hole in the bracket. The motor body includes a stator having a core with teeth and a coil formed of a winding wound around the teeth. The power supply structure includes, for each phase, a winding pair including a first lead portion and a second lead portion of the winding, a guide part that guides the winding pair, and a connector part where the lead portions are electrically connected. The winding pair includes a first portion guided by the ide part and a second portion formed by bending the winding pair at an axially outer end of the first portion along a surface of the bracket. The first portion passes through the through hole in the axial direction. The second portion extends to the connector part.
