Abstract: The motor includes a shaft fixed to a front surface side of a motor bracket; a rotor rotatably supported on the shaft; a stator wound with coils for generating a magnetic field to rotate the rotor; a substrate, a front surface of which mounted with a driver circuit for controlling magnetic field generation by the coils; a conductive driver case forming an accommodation space accommodating the substrate between itself and the motor bracket; a terminal disposed on a front surface side of the substrate facing the motor bracket and connecting the driver circuit and the coils; a conductive fixing member penetrating the substrate from a rear surface side and fixing the terminal in contact with the substrate; and an insulating driver insulator disposed on a rear surface side of the substrate to surround the fixing member, and protruding to a position closer to the driver case than the fixing member.

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.
