Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the preferred embodiment are only for convenience of description, and are not used to limit the scope of the present invention. The scope of implementation and the change or adjustment of its relative relationship shall also be regarded as the scope of implementation of the present invention without substantive changes in technical content.

[0036] Such as figure 2 As shown, the fan brushless motor includes a casing 2, a front cover 7 that buckles the opening of the front end of the casing 2, and a stator 5, a rotor and a PCB board arranged in the motor cavity formed by the casing 2 and the front cover 7 6. The rotor includes a rotating shaft 13, a circular cover-shaped magnetic frame 12 sleeved on the rotating shaft 13, and a plastic magnet 4 fixedly installed on th...

Abstract

A brushless fan motor includes the housing, a front cover with an opening at the front end of a housing, and a stator arranged in the motor cavity formed by the casing and the front cover, a rotor anda PCB. The rotor comprises a shaft,a magnetic frame sleeve on that rotating shaft in the shape of a circular cover and glue magnetism fixedly installed on the inner arc surface of the magnetic frame;the two ends of the rotating shaft are rotatably sleeved on the front cover and the bottom of the casing, and the frame opening of the magnetic frame coincides with the opening direction of the frontend of the chassis, wherein the stator is annular and suspended in the magnetic frame through a rotating shaft, front and rear bobbins clamping the stator are respectively arranged on both sides of the stator, a coil insulated from the stator is wound between the front bobbins and the rear bobbins, and the ends of the rear bobbins extend and are fixedly connected with the front covers for supporting the stator and the front bobbins. As that motor stator of the fan brushless motor of the invention doe not need the coat process, the cost is reduced, the pollution is reduced, and aft winding, the insulation performance is more stable and reliable, and the stator part can be disassembled and repaired repeatedly.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a fan brushless motor. Background technique [0002] A brushless motor is a typical electrical integration product in modern times, which has the advantages of low noise, high energy efficiency and durability. [0003] Such as figure 1 As shown, the stator part of a traditional brushless motor is generally composed of a stator 1, a PCB board 2, a zinc alloy bracket 3, and a motor front cover 4. 1 The purpose of insulation; the stator 1 and the PCB board 2 need to be locked and connected with the motor front cover 4 through the zinc alloy bracket 3 . This structure has the following disadvantages: [0004] 1) The stator 1 is fixed by the zinc alloy bracket 3 to connect the motor front cover 4. The structure of the zinc alloy bracket 3 is complex, and the material needs to be die-cast from zinc alloy. The assembly process is cumbersome, and after the assembly is completed, if the...
