Mining Drive Solutions
Large open-pit and underground mines worldwide adopt SUNSIN three-level MV/HV VFDs to cut power consumption, boost production efficiency and lift overall system value. We deliver customized drive solutions for belt conveyors, mine hoists, winches, underground emulsion pumps, mining fans and drainage pumps to satisfy all coal and mineral mining demands.
SUNSIN Mining VFD Series
Industry-specific Variable Frequency Drives for Underground & Open-Pit Mines
Deliver stable torque, intelligent speed regulation, 25%–65% energy saving and full safety protection.
What we do
SUNSIN manufactures robust industrial VFDs and supplies professional, energy-efficient drive solutions for global mining and heavy-duty industries.
Harsh Environment Adaptability
IP54/IP65 protection, anti-corrosion anti-condensation coating, working temperature -20℃ ~ +60℃, resist mine dust, mineral mist and high humidity.
Mine Safety Design
Optional flameproof and intrinsically safe units meet global mining standards, with full protection against overvoltage, overcurrent, overheat, phase loss, stall, short circuit and insulation failure.
Strong Heavy-Duty Drive Performance
Advanced vector control, 200% torque at low speed, perfect for heavy startup mining equipment.
Remarkable Energy-Saving Return
Dynamic load matching frequency conversion control, greatly lower operation power consumption for fans, pumps and conveyors.
Intelligent Mine Centralized Control
Support Modbus, Profinet and fiber-optic communication, seamlessly connect mine DCS system for remote monitoring, parameter modification and fault alarm push.
Low Maintenance Cost
Modular split power unit design for fast replacement without full-machine shutdown; energy feedback option for hoists and downhill conveyors to recycle wasted power.
Main Mining Application Scenarios
SUNSIN develops rugged mining-grade VFDs to offer reliable, energy-saving drive solutions for global underground and open-pit mines.
1. Mine Hoists & Lifting Winches
200% ultra-high low-frequency torque for heavy full-load startup; S-curve soft start/stop eliminates cable impact. Optional four-quadrant energy feedback recycles gravity power to cut electricity cost. SUNSIN MV3000 medium voltage series for 6kV/10kV large hoists.
2. Long-Distance Belt Conveyors
Master-slave multi-motor synchronous control & automatic power balance. Gentle soft startup avoids belt tension fracture, anti-slip and overload protection for long-distance ore transportation. Matched MV2000 heavy-duty VFD.
3. Main Mine Ventilation Fans
Real-time automatic air volume adjustment linked to underground gas and air pressure data. Reduce idle power loss by 30%–60% to guarantee underground ventilation safety. LV800 mining VFD with built-in PID constant air pressure control.
4. Underground Dewatering Pump Sets
Adaptive flow regulation following water inflow, constant pressure automatic drainage cycle. Avoid frequent motor start-stop and water hammer damage. Sealed dustproof cabinet fits humid tunnel conditions.
5. Crushers & Grinding Mills
150% rated overload lasting 60s to withstand irregular ore impact loads. Buffer startup protects gearboxes and rollers, stable speed adjustment to prevent blockage. MV2000 impact load dedicated model.
6. Roadheaders & Shearers
Flameproof XM series with complete mine explosion-proof certificates for gas coal mines. Fully sealed anti-dust structure, instant stall & overload protection to adapt to variable rock cutting loads.
