Five Differences Between Explosion-Proof Electric Heater Motors and Ordinary Motors - Yangzhou Darui

Darui Electric recommends for you
  The differences between explosion-proof electric heater motors and ordinary motors can be clearly seen in four aspects: application occasions, sealing performance, shape, and working purposes. The following is a detailed introduction to these aspects.
1. Different application occasions
  The main function of a general electric heater motor is to generate driving torque, serving as a power source for explosion-proof electric heaters or various machinery. In circuits, the motor of an explosion-proof electric heater is represented by the letter G, and its main function is to convert mechanical energy into electrical energy. Explosion-proof electric heater motors are generally used in flammable and explosive places, and they do not produce sparks during operation.
2. Sealing performance
  The sealing performance of the junction box of explosion-proof electric heaters is superior to that of ordinary electric heaters. Explosion-proof electric heaters are generally used in flammable and explosive occasions.
3. Shape
  Generally, the motor of an explosion-proof electric heater consists of a stator, rotor, and other accessories, forming the structure of a three-phase asynchronous motor. The protection level of explosion-proof electric heater motors is at least IP55, while ordinary motors have protection levels of IP23, IP44, IP54, IP55, IP56, which can be seen from the appearance.
4. Working purposes
  Explosion-proof motors do not produce sparks during operation. Their main uses are different: explosion-proof electric heater motors are mainly used in flammable and explosive enterprises such as coal mines, oil and gas, petrochemicals, and chemicals to drive pumps, fans, compressors, and other driving machinery.
