Pain Points & Solutions

Underground Hazards: Coal mines include unstable methane gas and flammable dust that may be ignited by ordinary engines. Our Ex d I Mb flameproof design features internal explosions so they do not ignite surrounding atmospheres.

Corrosive Environments Moisture and coal dust in mines speed up equipment wear. Multi-layer anti-rust coating and IP55 sealed housings protect against water intrusion and corrosion.

Mechanical Impact: Damage to normal equipment from underground impacts. The cast-iron body is thick and can endure serious physical blows throughout the mining process.

Maintenance Difficult Access Difficult repairs. Our motors have easy installation processes, including SKF, NSK, FAG bearings for optional longer service intervals.

Technical Advantages

High torque output ensures reliable operation under variable loads. Low noise and minimal vibration extend equipment lifespan while improving worker safety. Reinforced flameproof joint surfaces maintain precision clearances meeting coal mine safety regulations.

Production Process

Our manufacturing follows strict quality protocols. Precision machining creates flameproof joint surfaces within tolerance specifications. Multi-stage testing validates explosion containment capabilities before assembly. Each motor undergoes insulation resistance checks, high-voltage withstand tests, and no-load/load performance verification. Final inspection confirms explosion-proof clearances and cable entry integrity. SAP-managed production tracking ensures complete traceability from raw materials to finished units.

Industry Applications

YBS motors power critical underground coal mining equipment including:

· Conveyor belt systems transporting extracted coal

· Ventilation fans maintaining air quality in working faces

· Pumping stations removing groundwater accumulation

· Scraper conveyors moving materials in confined spaces

· Auxiliary drilling equipment for tunnel development

YBS low voltage explosion-proof coal mine motor operates reliably in methane-risk zones where standard equipment poses explosion hazards.

FAQ

Q：What is YBS low voltage coal mine explosion-proof motor and its explosion-proof mark?

A：YBS series is low-voltage flameproof three-phase aSynchronous Motor dedicated to underground coal mines. Its standard explosion-proof mark is Ex d I Mb, designed for underground environments containing methane and coal dust mixture.

Q：What voltage standards does YBS low voltage mine motor adopt?

A：It belongs to low-voltage mining motor, standard voltages 380V, 660V, dual voltage 380/660V, 50Hz. 1140V high-voltage type is not covered in YBS series; customers requiring 1140V shall select YBK3 series instead.

Q：What energy efficiency and main technical parameters of YBS motor?

A：YBS reaches IE3 high efficiency level; frame size H80-H315, power range 0.55–200kW, 2/4/6/8 poles optional; protection grade IP55, F-class insulation, IC411 self-fan cooling, S1 continuous working system.

Q：What reinforced design does YBS have to adapt to underground harsh working conditions?

A：Thickened cast iron flameproof housing provides impact resistance; multi-layer anti-rust coating resists moisture and corrosion; mine-dedicated cable entry device features multi-channel sealing; reinforced flameproof joint surfaces maintain precision clearances meeting safety standards.

Q：What is the difference between YBS low voltage motor and YBK3 mine explosion-proof motor?

A：YBS supports only 380V/660V low voltage while YBK3 covers 380/660/1140V. YBS maximum power reaches 200kW versus YBK3's 315kW capacity. YBS suits small-medium underground equipment; YBK3 serves large transport and mining auxiliary applications.
