The power motor of the raise boring rig is the core unit of the drilling rig’s energy conversion, directly driving the drill pipe and drill bit to achieve efficient rock breaking. LOOKING power motor sets a new industry benchmark in terms of torque density, energy efficiency conversion and adaptability to extreme environments.
Full-range constant torque characteristics: 0-30 RPM maintains 120 kN·m peak torque, hard rock starting efficiency increased by 50%;
Adaptive power regulation: The intelligent electronic control system matches the rock resistance in real time, and the power utilization rate reaches 95% (IEC 60034-30 standard).
Dual-channel cooling system: internal oil cooling + external water cooling design, winding temperature rise <70K (IEC 60085);
Vibration-resistant reinforced structure: shell reinforcement ribs + elastic base, resisting 10g vibration load (ISO 10816-3).
Multiple protection mechanisms: real-time monitoring of winding temperature/vibration/overload, fault response time <50ms;
Explosion-proof certified design: compliant with ATEX/IECEx Zone 1 standards, safe operation in methane environment.
Clean impurities in the cooling water channel (monthly), test the viscosity of the cooling oil (＞ISO VG 46).
Hard rock deep well: use high torque density type (≥650kW)
Large diameter expansion: dual motors in parallel (2×400kW) Balanced power distribution
High altitude operation: Plateau special version (heat dissipation enhanced by 30%) Derating temperature threshold adjustment
High humidity mine: Dehumidification type winding varnishing (H-level insulation) Automatic heating to prevent condensation
