AC Ki Motor

Super load capacity: drives high-pressure pumps, heavy machinery, and energy equipment.

Energy saving and efficient: 25%~30% more energy-efficient than single-phase motors, compatible with variable frequency speed regulation.

High reliability: protection level up to IP56, suitable for harsh environments.

Applicable scenarios: factories, ports, large farms, energy stations, etc. It is recommended to use an intelligent monitoring system to track the real-time running status.

The AC Ki Motor with its high power, strong torque, and reliability, is widely used in scenarios requiring heavy loads, continuous operation, or intermittent high-intensity tasks, particularly in industrial, agricultural, construction, and large-scale infrastructure fields. Below are its typical applications:

Industrial and Manufacturing Equipment

• High-Pressure Fluid Equipment: Industrial boiler feed pumps (pressure ≥1.6MPa, flow rate >20m³/h). Chemical process pumps (transporting corrosive liquids like acids or alkalis).
• Reason: High torque (≥2.8× rated torque) supports high-head, high-viscosity fluid transfer.
• Heavy-Duty Processing Machinery: Metal-cutting machine tool spindle drives (e.g., large lathes or milling machines). Injection molding machine hydraulic systems (clamping force >500 tons).
• Reason: High power density (>3.5kW/kg) enables intensive continuous processing.

Agriculture and Food Processing

• Large-Scale Irrigation Systems: Regional water transfer pump stations (lift >100 meters, irrigating 500+ acres). Aquaculture aeration systems (powering multiple aerators simultaneously).
• Reason: IP55 rating suits outdoor humid or dusty environments.
• Industrial Food Production Lines: Continuous baking equipment (driving hot air circulation fans at >200℃). Dairy homogenizers (high-pressure homogenization of milk or cream).
• Reason: High-temperature resistance (Class F insulation) ensures durability.

Commercial and Public Facilities

• Large HVAC and Refrigeration: District cooling system chilled water pumps (flow rate >30m³/h). Cold chain logistics freezer compressors (-30℃ ultra-low-temperature storage).
• Reason: High efficiency (IE4 class) reduces commercial energy costs.
• Heavy Logistics Equipment: Port container crane drives (lifting 10–20-ton cargo). Automated warehouse stackers (high-speed vertical/horizontal handling).
• Reason: Frequency converters (0–150Hz) enable precise speed control and energy savings.

Construction and Energy Projects

• Core Drives for Engineering Machinery: Tunnel boring machine cutterheads (hard rock excavation). Concrete pump truck hydraulic systems (pumping height >50 meters).
• Reason: Short-term overload capacity (200% for 30 seconds) handles sudden load impacts.
• Renewable Energy Systems: Small wind turbine pitch control systems (adjusting blade angles). Hydropower station auxiliary pumps (cooling water circulation and lubrication).
• Reason: Low vibration (<1.5mm/s) protects precision power generation equipment.

Power Supply: Three-phase 380V power (rated current ≈15A; use 20A circuit breakers). Avoid voltage fluctuations >±5% (add stabilizers to extend lifespan).

Load Management: Optimal load range: 85–100% (6.4–7.5 kW), efficiency >92%. For frequent starts/stops, use soft starters (inrush current ≤3× rated current).

Maintenance: Check bearing temperature every 500 hours (>85℃ requires shutdown). Clean internal dust annually (use dry compressed air).

Micro-scale or low-load applications (e.g., household appliances): Significant power waste.

High-frequency intermittent duty (e.g., spot welders with multiple starts/stops per second): Risks winding overheating.

Single-phase power setups: Requires converters, losing >30% efficiency.
