Explosion proof motors are motors that operate in flammable and explosive environments. In order to ensure work safety and prevent fire and explosion accidents, explosion-proof motors have a series of safety technical parameters. The following are some common safety technical parameters that Nanyang Explosion proof Motors will explain to you:

1. Explosion proof level: The explosion-proof level of an explosion-proof motor is determined based on its usage conditions in an explosive hazardous area, usually Exd, Exe, ExnR, or Exi levels.

2. Protection level: The protection level of explosion-proof motors determines their protection ability under external environmental conditions. Common protection levels include IP54, IP55, and IP66.

3. Temperature rise limit: Explosion proof motors generate heat during operation, and the temperature rise limit specifies the maximum allowable temperature rise of the motor under rated working conditions to ensure safe operation of the equipment.

4. Insulation level: The insulation level represents the heat resistance and voltage resistance of the motor insulation material, usually determined according to NEMA or IEC standards.

5. Material and process of key components: The key components of explosion-proof motors, such as the casing, winding, bearings, etc., need to be manufactured using special explosion-proof materials and processes to ensure their safety performance in hazardous environments.

6. Composition and concentration limits of explosive gases: There may be multiple harmful gases in the working environment of explosion-proof motors, and suitable explosion-proof motors need to be selected based on gas composition and concentration limits.

7. Ground conductivity: The shell of explosion-proof motors must have good conductivity to ensure safe discharge of static electricity and prevent static accumulation from causing fire accidents.

8. Grounding protection: The grounding protection of explosion-proof motors must comply with relevant standards to ensure reliable equipment grounding and prevent electrical fires caused by grounding faults.

The above are the common safety technical parameters of Nanyang explosion-proof motors. Choosing a suitable explosion-proof motor and strictly following relevant safety regulations for use and maintenance can effectively reduce the risk of fire and explosion in the working environment, and ensure the safety of personnel and equipment.
