Specifically, the stator core 2, the circuit board 1 and the bearing 8 are respectively fixed on a bearing retainer 4, and the bearing retainer 4 is fixed on the housing. The coil 3 is wound around the stator core 2. The shaft 5 is arranged in the motor axial direction; a rotor frame 6 is provided at an end of the shaft 5, and a rotor magnet 7 is provided on the rotor frame 6.
As shown in fig. 2, the circuit board 1 has an aluminum alloy layer, and the circuit board 1 has a through hole 101 penetrating in the axial direction; the end of the coil 3 is electrically connected to the circuit board 1 through the through hole 101; an insulating member 102 is provided in the circumferential direction of the through-hole 101. In the present embodiment, the aluminum alloy layer is disposed on the circuit board 1, so that the heat dissipation effect of the motor can be increased, and the through hole 101 is formed in the circuit board 1, and the insulating member 102 is disposed in the through hole 101, so that the short circuit of the circuit due to the presence of the aluminum alloy layer can be prevented, and the safety of the motor can be ensured.
The insulating member 102 is a rubber member, and the insulating member 102 can be easily attached to the through hole 101. The insulating member 102 is fixed to the through hole 101 by an adhesive, so that the insulating member 102 can be firmly fixed to the through hole 101, and the insulating member 102 is prevented from falling off when the motor is in a vibrating state, thereby improving the stability of the motor.
As shown in fig. 3 and 4, the present embodiment provides two different forms of the insulating member 102, but is not limited to the following two forms:
structure one (see fig. 3): the outer periphery of the insulating member 102 has a flange portion 103 protruding outward; the flange portion 103 axially overlaps the circuit board 1 around the through hole 101, and the overlapping portion is fixed to the circuit board 1.
Structure two (as in fig. 4): the insulating member 102 has a flange portion 103 protruding outward on one axial side thereof. The flange portion 103 and the circuit board 1 are fixed to each other, so that the fixing strength is improved. By forming the flange portion 103 on one side, the insulating member 102 can be attached to the through hole 101 relatively easily.
