Manufacturing Process

1. Standard silicon steel lamination and stator/rotor die-casting.
2. 100% copper winding and stator insertion.
3. Vacuum impregnation and specialized drying process.
4. CNC machining for motor shaft, frame, and end shields.
5. Professional inspection at every processing stage.
6. Full assembly line and 100% testing before painting.
7. Final check of output power, load capacity, and nameplate before packing.

Packaging & Standards

Package: Export fumigation wooden case

YB2/YB3 ranges of three-phase induction motors are explosion-proof motors designed for safety and efficiency. These motors offer high locked-rotor torque, low noise, and minimal vibration.

Explosion-Proof Ratings:
- ExdI: Safe for underground coal mines (methane/coal-dust atmospheres).
- ExdIIAT4/BT4/CT4: Safe for industrial plants with explosive gas mixtures of Class IIA, IIB, or IIC.
