Problems solved by technology

[0002] The existing motor combined base includes a front end cover, a housing, and a rear end cover. Bearings are installed in the front end cover and the rear end cover. When the motor is running, the bearings in the front end cover and the rear end cover generate a certain amount of heat. A large amount of heat is generated, which will increase the temperature of the bearings in the front end cover and rear end cover, affecting the normal use of the bearings
Therefore, the combined motor base of the prior art has taken certain cooling measures, such as the front end cover, the housing, and the rear end cover are all provided with an inner cavity interlayer, and after being connected, a cooling water channel is formed to cool the front end cover and the rear end cover. Bearings are cooled. This motor combined frame can cool the bearings in the front end cover and rear end cover to a certain extent. However, if the motor load is relatively large and the heat generated is relatively large, this motor combined frame cannot Sufficient cooling of the bearings in the front end cover and rear end cover cannot guarantee the normal use of the bearings in the front end cover and rear end cover

Abstract

The invention discloses a composite cooling motor, which comprises a front end cover, a casing and a rear end cover; the front end cover, the casing and the rear end cover are all provided with a cooling water channel formed by an inner cavity interlayer, a water inlet joint and a water outlet joint; the rotor It is a copper rotor; its improvement is: there is a cooling air passage Ⅰ in the front end cover, a cooling air passage Ⅲ in the rear end cover, and the combination of the cooling air passage Ⅰ in the front end cover, the inner cavity of the shell, and the cooling air passage Ⅲ in the rear end cover into a motor cooling air duct; further improvement lies in: the water outlet joint Ⅰ on the front cover is connected with the water inlet joint Ⅱ on the outer wall of the housing through the pipeline, and the water outlet joint Ⅱ on the outer wall of the housing is connected with the water inlet joint Ⅲ on the rear end cover through the pipeline ; The rotor is a cast copper rotor. The invention has high efficiency and good reliability.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a combined motor base. Background technique [0002] The existing motor combined base includes a front end cover, a housing, and a rear end cover. Bearings are installed in the front end cover and the rear end cover. When the motor is running, the bearings in the front end cover and the rear end cover generate a certain amount of heat. A large amount of heat is generated, which will increase the temperature of the bearings in the front end cover and the rear end cover, affecting the normal use of the bearings. Therefore, the combined motor base of the prior art has taken certain cooling measures, such as the front end cover, the housing, and the rear end cover are all provided with an inner cavity interlayer, and after being connected, a cooling water channel is formed to cool the front end cover and the rear end cover. Bearings are cooled. This motor combined frame can cool the ...
