AI Technical Summary
Existing dustproof brushless motors have difficulty dissipating heat after prolonged operation, and the external protective box affects heat dissipation, leading to heat accumulation inside.
A dustproof brushless motor was designed. By setting a breathable filter and baffle on the motor housing, and using an electromagnet and centrifugal force to control the opening and closing of the baffle, automatic heat dissipation and dust prevention effects are achieved.
It achieves automatic opening of heat dissipation holes for heat dissipation when the motor is working, and automatic covering for dust protection when it stops working, thus improving heat dissipation efficiency and dust protection effect.
