Abstract

The invention discloses a cooling device for a brushless motor of a vacuum cleaner, which includes a moving impeller wind cover, a moving impeller, a fixed impeller, and a motor casing, and the moving impeller wind cover is arranged on the outside of the moving impeller; the cooling device also It includes a motor fan cover arranged on the outside of the motor casing, the motor fan cover has an end part and a peripheral side part, a gap is provided between the peripheral side part and the motor casing, the moving impeller fan cover, the fixed An air flow channel is formed among the impeller, the motor fan cover and the motor casing. The invention can be used in various vacuum cleaner motors or similar motor structures, and has the advantages of rapidly reducing the heat of the motor, reducing the temperature of the casing, and the like.

Description

technical field [0001] The invention relates to the technical field of a brushless motor, in particular to a cooling device for a brushless vacuum cleaner motor. Background technique [0002] The vacuum cleaner is a cleaning appliance that uses a motor to drive the impeller to rotate at high speed to generate negative air pressure in the sealed housing, thereby sucking dust and other debris into the dust bag. The high-speed rotating rotor is easy to generate a lot of heat. Since most of the motors adopt a closed structure and there is no reasonable heat discharge device, the heat is easy to accumulate and not easy to dissipate. Eventually, the temperature of the enameled wire winding of the motor is much higher than the original one, and the insulation layer of the enameled wire is damaged. The service life will be shortened as the temperature increases, and the temperature of the motor casing will increase accordingly. [0003] The casing temperature of the motor is too hi...
