Abstract

The invention provides an explosion-proof motor which can accelerate internal heat dissipation of the motor and is not easy to accumulate dust. The explosion-proof motor comprises a rotor and an explosion-proof shell. The rotor is sleeved on the rotating shaft; a junction box is arranged at the top of the explosion-proof shell; a front end cover of the explosion-proof shell is provided with a heatdissipation opening, and a rear end cover of the explosion-proof shell is provided with an air inlet; the rotating shaft penetrates through the front end cover and the rear end cover; the rear end ofthe rotating shaft is sleeved with a fan. The motor is characterized in that a cold plate placing groove is formed between the rotor and the fan; a groove opening for taking and placing a cold plateplacing groove is formed in the cylindrical part of the rear end cover; and a sealing cover is arranged on the cold plate placing groove.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an explosion-proof motor. Background technique [0002] Explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric sparks during operation. Mainly used in coal mines, oil and gas, petrochemical and chemical industries, usually used to drive pumps, fans, compressors and other transmission machinery. [0003] The prior art discloses an explosion-proof motor with the application number: 201721810736.0, which includes a casing and a rotating shaft, including a housing, a front end cover, a rear end cover, a windshield and a base, and the front end cover and the rear end cover are respectively arranged on the casing The left and right sides of the windshield are arranged on the outside of the rear end cover, the inner wall of the housing is coated with a layer of waterproof coating, the inside of the waterproof coating i...
