Frequently Asked Questions
1. What is a dust explosion-proof motor?
It is a specially designed motor for environments where combustible dust (like flour, grain, or magnesium powder) exists. It prevents the ignition of the dust atmosphere surrounding the motor.
2. What certifications do the YFB3 series motors have?
The motors have obtained domestic explosion-proof certification, energy efficiency certification, CCC certification, international IECEx certification, and ATEX certification.
3. Can the motor color be customized?
Yes, we employ professional certified painters and can mix any color to match your specific industrial requirements.
4. What is the power range for these motors?
The YFB3 series covers a wide range of power requirements, from 0.55KW up to 315KW, with frame sizes ranging from H80 to 355.
5. How is the motor protected against harsh environments?
The motors feature IP55 or IP65 protection ratings and are fully enclosed with self-fan cooling (IC411), ensuring safe operation in dusty and demanding industrial settings.
6. What type of starting mode is used?
The standard starting mode is Direct On-Line (DOL) starting, designed for efficiency and reliability in three-phase power systems.
