AC Squirrel Cage Induction Motor

Engineered for demanding industrial environments, AC Squirrel Cage Induction Motor delivers 1.1kW continuous stable output with 220V single-phase compatibility (±10% voltage tolerance), eliminating costly three-phase conversion. Its reinforced cast aluminum frame ensures durability in high-vibration settings like mining and farming, while national standard copper windings guarantee conductivity and longevity.

Featuring a fully enclosed IP55 protection design, it resists dust and moisture intrusion, ideal for harsh operations. The optimized single-capacitor architecture simplifies maintenance with no centrifugal switches, and the low-noise fan enhances workplace comfort.

Certified to IEC and NEMA standards, this energy-efficient motor supports heavy-load startups (e.g., rock crushers, pellet mills) with scientifically calibrated torque. A cost-effective, plug-and-play solution backed by global technical support and OEM warranties.

1, Heavy-Duty Industrial Power Upgrade

High Starting Torque: Designed for heavy loads like industrial air compressors and hydraulic systems, achieves 2.3× rated starting torque (industry average: 2.0×) without auxiliary starters.

Impact-Resistant Structure: Reinforced cast iron housing (15mm wall) + upgraded base bolt holes, passes GB/T 29531 200% instantaneous overload test (100,000 cycles).

2, Extreme Environment Durability

High-Temperature Operation: Class F insulation (155°C rated) + optimized cooling airflow design enables continuous operation in 55°C environments.

Enhanced Protection: IP55 rating: Double shaft sealing (rubber seal + dust cover) resists dusty environments (≤200mg/m³).

Anti-corrosion coating: Multi-layer anti-rust paint (500-hour salt spray tested) for chemical/agricultural applications.

3, High Efficiency & Longevity

IE3 Efficiency: ≥91.5% tested efficiency, significantly saving electricity costs vs. standard motors (24/7 operation, ¥0.8/kWh).

Bearing System: C3 deep groove ball bearings (58kN dynamic load) with 5,000-hour lubrication intervals (heavy-duty), reducing maintenance by 30%.

Industrial Application Scenarios

Air Compressor Drives: Directly drives 18m³/min screw compressors with 100% startup success (field-tested). Optimized airflow prevents overheating in high-temperature workshops.

Agricultural Machinery: Optional shaft anti-winding guard for straw crushers and feed mixers. Rust-proof coating extends lifespan in humid/dusty farmland conditions.

The 4 kW three-phase motor, with its high power output, efficiency, and reliability, is suitable for medium to heavy loads and continuous or intermittent operation. It is ideal for driving larger equipment in industrial, agricultural, and commercial settings. Below are its typical application areas and examples:

1. Industrial and Manufacturing Equipment

• Medium-Sized Pumps and Fans: Industrial circulation water pumps (for cooling systems or boiler water supply). Large workshop ventilation systems (e.g., smoke extraction in welding workshops).
• Reason: The 4 kW motor provides higher torque, meeting demands for high flow rates and pressure (e.g., pumps with lifts exceeding 40 meters).
• Heavy-Duty Conveyor Systems: Logistics sorting line drives (conveyor belts carrying loads over 100 kg). Mining/construction material belt conveyors (continuous transport of gravel or ores).
• Reason: High starting torque (≥2.2× rated torque) ensures smooth heavy-load startups.

2. Agriculture and Food Processing

• Large Irrigation and Drainage Systems: Deep-well pumps (lifts over 50 meters, irrigating 100+ acres of farmland). Feed processing crushers (handling high-hardness materials like corn or straw).
• Reason: Three-phase motors tolerate voltage fluctuations common in rural power grids.
• Food Processing Equipment: .Large mixing tank drives (blending sauces or chemical ingredients). Meat processing lines (powering cutters or packaging machines).
• Reason: IP55 protection rating resists moisture and grease in harsh environments.

3. Commercial and Public Facilities

• Large HVAC and Refrigeration Systems: Commercial cold storage compressors (-25℃ low-temperature freezers, continuous cooling). Mall central air-conditioning chilled water pumps (circulating ≥10 m³/h water flow).
• Reason: High motor efficiency (up to 90%) reduces long-term electricity costs.
• Elevators and Lifting Equipment: Freight elevator drives (vertical lifting systems for 1–3 ton loads).
• Reason: Frequency converters enable smooth starts/stops, minimizing mechanical stress.

4. Construction and Engineering Machinery

• Concrete Mixers: Mobile construction-site mixers (volumes ≥500 liters).
• Reason: 4 kW motors handle intermittent heavy loads (e.g., resistance from mixing stones and cement).
• Air Compressors: Industrial-grade compressors (0.8–1.0 MPa pressure, powering pneumatic tools).
• Reason: High power matches large air displacement requirements (≥1.2 m³/min).
