Application Scenarios and Selection Principles for Explosion-Proof Motors
Three-step selection process: ① Identify the hazardous area (Zone 0/1/2, or Dust Zones 20/21/22); ② Determine the gas group (IIA/IIB/IIC) and the dust type, as well as the ignition temperature; ③ Match the explosion-proof type and equipment protection level (EPL: Ga/Gb/Gc, Da/Db/Dc).

Core Explosion-Proof Type and Principle
The most widely used type; the enclosure is made of high-strength cast iron, die-cast aluminum, or welded steel plate, providing explosion resistance (withstanding internal explosion pressure without rupture) and non-transmission of explosion (achieved through precise flameproof gaps and sufficiently long flame paths that cool the flame below its ignition temperature); suitable for Zone 1 and Zone 2; commonly found in underground coal mines and in pump and fan drives at oil refineries.

Development Trends of High-Efficiency Three-Phase Induction Motors
The high-efficiency three-phase induction motor market is currently in a golden growth phase driven by policy, economic factors, and technological advancements, with China poised to take the global lead. Over the next five years, the main trends will be accelerated penetration of IE4 and IE5 efficiency classes, deeper integration of intelligent technologies, domestic substitution, and service-oriented upgrades—all of which will benefit in the long term from the industrial green transition and the “dual carbon” goals.
