AI Technical Summary

Technical Problem

When using a brushless DC motor, the fan heat dissipation method will bring in external impurities, affecting the operating efficiency of the motor.

Method used

A DC motor is designed, which uses the inner cavity of the flow chamber to set up liquid and balls, and the balls are driven to move in the thread direction through the rotor assembly, driving the liquid circulation to dissipate heat. At the same time, the air flow path designed by the spiral groove is used to accelerate air conduction, achieving effective heat dissipation of the rotor assembly.

Benefits of technology

Through the power drive of liquid and air, efficient heat dissipation of the motor is achieved, the problem of impurities brought into the fan is avoided, and the operation efficiency and reliability of the motor are improved.

Abstract

The present invention relates to the technical field of direct current motors, and discloses a direct current motor, including a motor housing, wherein the outer wall of the motor housing is fixedly equipped with a heat dissipation component, the top of the motor housing is fixedly equipped with an end cover, the bottom of the motor housing is fixedly equipped with a bottom cover, the inner wall of the bottom cover is fixedly equipped with a bearing 1, the inner cavity of the bearing 1 is fixedly equipped with a rotating shaft, the outer wall of the rotating shaft is fixedly equipped with a rotor component, the outer edge of the rotor component is sleeved with a stator core with windings, and the two ends of the rotor component are fixedly equipped with rotor balance rings. Liquid is set through the inner cavity of the flow bin, and balls are set in the liquid. The rotor component is used to rotate along the thread direction of the flow bin with the rotating shaft as the axis. The magnetic force of the rotor component on the balls makes the rotor component drive the balls to move in the thread direction of the flow bin, so that the liquid is driven by the power of the rotor component, so that the main body of the device can achieve heat dissipation.
