3 Phase AC Electric Motor

This high-performance 3-phase AC motor delivers 1.1KW continuous stable output (220V±10%), engineered for heavy-duty equipment like rock crushers and feed pellet mills. Featuring reinforced cast aluminum housing for shock resistance in mining and farming environments, it combines optimized electromagnetic design for high torque startup and fully sealed protection against dust/moisture. The low-noise fan system and precision bearings ensure quiet operation, while national standard copper windings guarantee conductivity and durability. Compatible with single-phase 220V power, it eliminates three-phase conversion costs and requires minimal maintenance. Ideal for industrial automation, agriculture, and manufacturing, this energy-efficient motor meets IEC standards for global procurement.

1, Heavy-Duty Impact Resistance Design

Military-Grade Structural Integrity: Full cast iron housing (HT250 material, 12mm wall thickness) passes GB/T 29531-2013 impact resistance testing (300% instantaneous overload, 100,000 cycles without cracks). Reinforced base bolt holes (M12 high-strength bolt interfaces) adapt to severe vibration in mining and building material processing equipment.

Ultra-High Starting Torque: 3.0× rated starting torque directly drives high-inertia loads like jaw crushers and Industrial Heavy-Duty Wood Sawing Machines without hydraulic couplings or soft starters.

2, Extreme Environment Adaptability

Wide Temperature Range Operation: -25°C Cold Start: Optional embedded winding heating strips with -40°C low-temperature lubricant, achieving 100% startup success in Arctic projects. +60°C Continuous Operation: Class H insulation (180°C rated) +Independent Forced-Air Cooling System (external IP55 fan), tested with ≤75K temperature rise in desert oilfield environments.

Specialized Protection: Sandproof Sealing (IP54S rating): Triple labyrinth seals at the shaft end withstand sandy environments (95% dust-blocking efficiency verified in Saudi cement plants). Salt Spray Resistance: Epoxy + fluorocarbon coating (1,000-hour salt spray test) for coastal ports and ship deck applications.

3, Heavy-Load Performance Verification

Overload Capacity: Sustains 250% rated load for 1 minute without tripping (industry average: 150%), ideal for sudden material jams in mining crushers.

Bearing Lifespan: 6312/C4 spherical roller bearings (dynamic load capacity 68kN) with 3,000-hour lubrication intervals (under heavy loads), offering 120% longer lifespan vs. standard deep groove bearings.

Vibration Control: G2.5 dynamic balancing + elastic base damping design ensures full-load vibration ≤2.0mm/s (ISO 10816-3 standard).

4, Real-World Harsh Environment Case Study

Case 1: Gold Mine Crusher Drive (Western Australia) Equipment: 1.5kW motor driving PE250×400 jaw crusher Conditions: Ambient temperature -15°C~+55°C / 200 daily overloads / 300mg/m³ dust concentration Test Data: ✓ 65% reduction in annual failure rate (vs. original motor) ✓ 18% lower starting current (optimized star-delta switching) ✓ 18 months of continuous operation without overhaul
