The explosion-proof electric hoist is mainly divided into three and four levels of explosion-proof, and its motors are also classified into different levels. Due to the special working environment of the explosion-proof hoist, there are some dangerous factors inherent in it, so choosing an explosion-proof motor is even more crucial. The following party will provide you with a detailed introduction to the five explosion-proof levels of the motor in the explosion-proof hoist:

　　1. According to the explosion-proof principle, it is divided into explosion-proof, increased safety, positive pressure, non-sparking, and dust explosion-proof motors.

　　2. According to motor principles, it can be divided into explosion-proof asynchronous motors, explosion-proof synchronous motors, and explosion-proof DC motors.

　　3. According to the place of use, it can be divided into explosion-proof motors used underground in coal mines and explosion-proof motors used in factories.

　　4. According to rated voltage and efficiency, it is divided into high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high slip explosion-proof motors, and high starting torque explosion-proof motors.

　　5. According to the combination of components, it can be divided into explosion-proof motors for metallurgy, explosion-proof motors for coal mine transport machines, explosion-proof motors for valves, explosion-proof motors for fans, explosion-proof motors for ships, and increased safety brushless excitation synchronous motors for hydrogen refueling devices.

　　When purchasing explosion-proof electric hoists, please provide a detailed explanation of the applicable location and requirements. It is particularly important to choose the appropriate motor according to different working environments.
