Main Mining Application Scenarios

SUNSIN develops rugged mining-grade VFDs to offer reliable, energy-saving drive solutions for global underground and open-pit mines.

Mine Hoists & Lifting Winches

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.
