Pain Points vs. Solutions

​​​​​​​

Technical Advantages

The YBK3 series delivers exceptional performance through intelligent engineering. High-efficiency design ensures maximum output with minimal energy waste. Large torque capability provides strong overload capacity for demanding mining operations. The thickened cast iron flameproof housing withstands collisions and impacts common in underground environments. Premium SKF, NSK, or FAG bearings can be installed based on your specifications. IP55 protection grade with F-class insulation guarantees reliability in humid conditions. The IC411 self-fan cooling system maintains optimal operating temperatures during continuous S1 duty cycles. Low noise and minimal vibration contribute to safer working conditions.

Production Process

Our manufacturing partners implement SAP factory management systems ensuring consistent quality control. Each motor undergoes precision machining of flameproof joint surfaces with specialized anti-rust treatment. Mine-specific sealed cable entry devices are installed to prevent gas, water, and coal dust intrusion. Enhanced anti-corrosion coatings are applied through multi-layer processes. Available frame sizes from H80 to H355 are built to close dimensional specifications. Final assembly comprises complete testing procedures to guarantee explosion-proof integrity, electrical performance and mechanical strength prior to shipping.

Applications in Industry

The greatest advantages of exd motor technology are shown in underground coal mining activities, especially on working surfaces where methane mixes are explosive dangers. They operate conveyor, ventilation, drill and material handling machines. The rugged structure is suited for harsh subsurface environments, including humidity, dust and physical stress. Flameproof motors are used for petrochemical plants, offshore platforms and pharmaceutical industries where volatile atmospheres need verified explosion protection.

FAQ

Q：What is YBK3 motor and what explosion-proof mark does it carry?

A：coal mines. Its standard explosion-proof certificate mark is Ex d I Mb, applicable to underground coal mine environments containing methane and coal dust.

Q：What energy efficiency grade does YBK3 coal mine explosion-proof motor reach?

A：YBK3 series reaches IE3 high-efficiency standard, conforming to national energy efficiency standards for mining motors. Compared with old YBK2 series, it has lower loss, lower temperature rise, and saves power consumption during long-time underground continuous operation.

Q：What are the main technical specifications of YBK3 series?

A：Frame size H80–H355; power range 0.18–315kW; 2/4/6/8 poles optional; standard mine special voltage 380V/660V/1140V 50Hz; protection grade IP55, F-class insulation, IC411 self-fan cooling, S1 continuous working system.

Q：What is the difference between YBK3 mine flameproof motor and YBX3 factory gas explosion-proof motor?

A：YBK3 carries Ex d I Mb certification for underground coal mine methane environments, while YBX3 has Ex d ⅡBT4 for factory flammable gas. YBK3 prioritizes mine-special 1140V high voltage and features thicker shells with stronger anti-rust and waterproof performance.
