Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, a high heat dissipation motor comprises a housing 1 and a rear cover 4, wherein a plurality of groups of heat dissipation ridges 2 are annularly arranged on the housing 1, a group of heat dissipation grooves 3 are formed between every two groups of adjacent heat dissipation ridges 2, a plurality of groups of connecting blades 5 are arranged on the front end face of the rear cover 4 in an array manner, each group of connecting blades 5 is correspondingly connected with the rear end face of each group of heat dissipation ridges 2, a group of air passing windows are formed at the connection position of each group of heat dissipation grooves 3 and the rear cover 4, and a group of fans 6 are arranged in a container cavity in the rear cover 4.

Aiming at the heat dissipation problem of the existing motor, the rear cover 4 of the scheme is directly connected with the heat dissipation ridge 2 of the shell 1, so that an air passing window is formed at the position of the heat dissipation groove 3, when the fan 6 rotates to generate flowing air flow, part of the air flow passes through the inside of the motor to dissipate heat of an internal component, and the other part of the air flow passes through the air passing window along the heat dissipation groove 3, so that the shell 1 is dissipated from the outside, and the internal heat is better sent out;

it should be noted that the motor structure of this scheme has poor tightness, so the motor needs to be subjected to dust-proof treatment or used in a dust-free environment when the motor is assembled.

Further, the radial length of the fan 6 is slightly larger than that of the housing 1.

In this scheme, the diameter of fan 6 is greater than the diameter of casing 1 and is less than the diameter of back lid 4, and when fan 6 is rotating, a part of air current can follow excessive window and dispel the heat to motor casing 1 along heat sink 3, and another part of air current can be from the inside heat dissipation treatment of motor by the air current that fan 6 drove.

Further, an air inlet window 8 is formed in the rear end face of the rear cover 4.

The air inlet window 8 is a cold air flow air inlet of the motor.

Further, a rotation shaft 9, a rotor core 10 and a stator winding 11 are provided inside the casing 1, and the fan 6 is connected to the rear end of the rotation shaft through a bearing.

Working principle: the rear cover 4 is directly connected with the heat dissipation ridge 2 of the housing 1, so that an air passing window is formed at the position of the heat dissipation groove 3, when the fan 6 rotates to generate flowing air flow, part of the air flow passes through the inside of the motor to dissipate heat of the internal components, and the other part of the air flow passes through the air passing window along the heat dissipation groove 3, so that the housing 1 is cooled from the outside, and internal heat is better sent out.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
