The invention belongs to the technical field of motors, and relates to an explosion-proof variable frequency brake motor. The explosion-proof variable frequency brake motor comprises a shell, the axial front end of the shell is fixedly connected with a front cover, the axial rear end of the shell is fixedly connected with a rear motor cover, the axial end surface of an inner ring cylinder body part of the rear motor cover is provided with a rear cover, a rotating shaft is rotationally arranged in the shell, the axial two ends of the rotating shaft are respectively supported on the front coverand the rear cover, and an explosion-proof cooling fan is arranged on the flange surface of an outer ring of the rear motor cover; the rear motor cover is provided with a brake, a disc of the brake isarranged on the rotating shaft and rotates together with the rotating shaft, a winding is arranged in the shell around the rotating shaft, a threading channel is arranged between the winding and theshell, a lead of the winding is connected into a junction box, and the junction box is arranged on the shell. The explosion-proof variable frequency brake motor of the invention has a reasonable and ingenious structure, convenient implementation, safe and reliable use and conforms to the explosion-proof requirement; and moreover, the rear motor cover of the product is provided with the air passage, so that the explosion-proof cooling fan effectively blows air to the surface of the shell in the working process to cool the fan.
Description
technical field [0001] The invention belongs to the technical field of electric motors, and relates to an explosion-proof variable frequency brake electric motor. Background technique [0002] At present, the country has successively issued and updated the implementation standards of explosion-proof motors. There are also special industry standards for explosion-proof variable-frequency motors to guide and focus on, but there are not many relevant regulations on explosion-proof variable-frequency motors with brake requirements, and the reference materials are extremely limited. Contents of the invention [0003] In view of the above problems, the present invention provides an explosion-proof frequency conversion brake motor, which has a novel structure, meets the requirements of explosion-proof, and is safe and reliable. [0004] According to the technical solution of the present invention: an explosion-proof variable frequency brake motor, it is characterized in that it i...
