Description

Technical Field

[0001] The utility model relates to an explosion-proof motor, in particular to an explosion-proof brake motor based on a novel stator iron core structure, belonging to the technical field of explosion-proof motors. Background Art

[0002] An explosion-proof motor is a motor with explosion-proof function. The design and manufacture of explosion-proof motors are mainly to prevent the motor from exploding in an explosive environment, thereby ensuring the safety of personnel and equipment. Explosion-proof motors are usually used in industries such as petroleum, chemical, and natural gas, where flammable and explosive gases or liquids exist.

[0003] In some environments where flammable and explosive gases exist, explosion-proof motors are generally used. When sparks are generated inside the explosion-proof motor, the outer casing can effectively isolate the sparks from the external environment. When the explosion-proof motor runs for a long time and an explosion occurs inside, the surface temperature of the explosion-proof motor will rise. When the temperature rises to the ignition point of the flammable gas in the environment, it will cause explosions and fires. The existing heat dissipation method for explosion-proof motors is usually to set a cooling fan at the rear of the explosion-proof motor to dissipate the heat of the explosion-proof motor. However, the cooling fan can only dissipate the heat of the outer casing, but cannot effectively dissipate the heat inside the explosion-proof motor, resulting in internal heat accumulation of the explosion-proof motor, and a lag in the heat dissipation of the explosion-proof motor, which affects the heat dissipation effect of the explosion-proof motor, shortens the service life of the explosion-proof motor, and is not conducive to the long-term use of the explosion-proof motor.
