AI Technical Summary

Technical Problem

During operation, existing brushless DC motors cannot effectively absorb heat through coolant, use heat dissipation fins to expand the heat dissipation area, and discharge heat through fans and heat dissipation holes, resulting in the motor being unable to operate stably under appropriate temperature conditions.

Method used

A brushless DC motor with a new heat dissipation structure is designed, including a heat dissipation assembly, a clamping assembly and a regulating assembly. The heat dissipation assembly realizes heat absorption, diffusion and discharge through the combination of a coolant cylinder, a heat dissipation fin and a small fan; the clamping assembly realizes stable clamping of the motor main body through a curved plate, a rubber pad and a slide rod; the adjustment assembly realizes position adjustment of the motor main body and the heat dissipation cylinder through a micromotor and a threaded rod.

Benefits of technology

Through this design, the motor can effectively cool down during operation, ensuring the motor can operate stably under appropriate temperature conditions, reducing the risk of failure caused by overheating, and improving the stability and adaptability of the motor.

Abstract

The invention relates to the technical field of brushless direct current motors with novel heat dissipation structures, and discloses a brushless direct current motor with a novel heat dissipation structure, which comprises a brushless direct current motor main body, a heat dissipation assembly is arranged outside the brushless direct current motor main body, and a clamping assembly is arranged outside the heat dissipation assembly. Heat generated in the operation process of the brushless direct current motor body is primarily cooled through the cooling liquid cylinder, the cooling liquid absorbs the heat of the motor shell and enables the heat to be transmitted to the upper cooling fins and the lower cooling fins on the motor shell, part of the heat is released to the surrounding air through the heat dissipation area expanded by the fins, meanwhile, the small motor is started, and the heat dissipation efficiency is improved. The rotating rod is driven to rotate, then the fluted disc, the connecting rod and the small fan are driven to perform circular motion together, residual heat is discharged outdoors through the heat dissipation holes of the heat dissipation cylinder, heat dissipation of the brushless direct current motor body is achieved, it is ensured that the motor operates in a proper temperature environment, and the risk of faults caused by overheating is reduced.
