Abstract: The motor includes a circuit board that controls the generation of a magnetic field for rotating a rotor by supplying currents to coils, and a slit terminal (60U) that electrically connects a winding wire to the circuit board. The slit terminal (60U) includes a pair of legs (63A, 63B) arranged to face each other across the winding wire (244U) at an interval that is narrower than a diameter of a core wire. A motor bracket includes a terminal holder (43U) that has peeled piece accommodation spaces (52A, 52B) for accommodating the peeled pieces (245U) peeled off from the winding wire (244U) press-fitted between the pair of legs (63A, 63B).

Abstract: A fan device (1) includes a shroud (4) including a motor support unit (42), a fan (3) disposed on a surface side of the motor support unit (42), and a motor (2) supported on a rear side of the motor support unit (42). Multiple air guide passages (426) each penetrating in a thickness direction at positions spaced apart in a circumferential direction and radially outward from a boss 31 of the fan (3) are formed in the motor support unit (42). The fan device (1) further includes an air guide unit (52) that is disposed facing the air guide passage (426) on the rear side of the motor support unit (42), and guides cooling air generated by the fan (3) and passed through the air guide passage (426) to a rear side of a motor bracket (21).

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.
