Description

Technical Field

[0001] The utility model relates to the technical field of motor heat dissipation, and more particularly to a brushless motor with high-efficiency heat dissipation. Background Art

[0002] It is an improved motor designed to address the high-heat environment problem generated by traditional brushless motors during long-term operation. This brushless motor with efficient heat dissipation effectively solves the problem of traditional brushless motors being affected by high-heat environments during long-term operation through its unique structure and innovative heat dissipation mechanism. Its design and implementation has brought new breakthroughs in the field of motor technology and is expected to be widely used in multiple industries such as automation control, medical equipment, and mechanical processing.

[0003] However, the heat dissipation structure of existing brushless motors mostly uses external heat dissipation devices. Although this method can effectively dissipate heat, it increases production costs. In addition, these external devices usually require more installation and maintenance work, further pushing up the total cost of ownership. Due to the structural complexity of the external heat dissipation device, once a failure occurs or maintenance is required, the repair process is often cumbersome and the maintenance cost is relatively high.

[0004] In addition, during long-term use, dust and impurities in the air will inevitably enter the interior of the motor and accumulate on various components. As the running time increases, these dust will form a layer of dirt on the radiator, circuit board and other key components. This layer of dirt not only reduces the heat dissipation efficiency of the motor, but may also cause overheating, thereby affecting the performance and life of the motor. The accumulation of dust may also cause electrical problems such as short circuits, posing a threat to the stable operation of the motor.

[0005] Therefore, in order to solve the above problems, the present application provides a brushless motor with efficient heat dissipation. Utility Model Content

At this time, air enters the inner cavity of the main shell from the air vent and filters larger particles in the air through the filter holes provided on the filter disc, thereby preventing particles from entering the winder and the stator coil and causing the circuit on the Hall element to short-circuit, thereby damaging the original component.

[0012] The technical effects and advantages of this utility model are:

[0013] When the motor starts running, the second clamping post moves the first clamping post and the first clamping block downward as a whole. The first clamping block clamps the cooling fan and the rotating column under the action of the compression spring. At this time, the cooling fan starts to rotate with the rotating column as the axis, driving air to blow to the rotating assembly to dissipate heat and cool the entire assembly.
