With a rated power of 2.2KW (3.0HP), operating voltage of 220V, frequency of 50Hz, rotational speed of 3000R/min, rated current of 13.4A, and net weight of 16KG, it delivers strong torque (7.06N·m) for heavy-duty tasks. Key features include a dual-capacitor design (C1: 50μF/450V, C2: 250μF/30V), CSA security certification, a cast iron casing, and IP44 protection rating. Unlike three-phase motors, this single-phase model is compatible with standard household or small workshop power supplies (220V), eliminating the need for three-phase power installation. It is ideal for driving equipment such as water pumps, compressors, and small machinery, combining power, safety, and ease of use.
Dual-Capacitor Design: The motor uses two capacitors for optimal performance: (1) The start capacitor (C2: 250μF/30V) provides high starting torque (14.12N·m) to help the motor start quickly (within 2 seconds) under load; (2) The run capacitor (C1: 50μF/450V) stabilizes power output during operation, improving power factor (≥0.85) and reducing energy consumption.
High-Speed, High-Torque Operation: With a rotational speed of 3000R/min and rated torque of 7.06N·m, the motor can drive heavy-duty equipment such as 2-inch water pumps or small air compressors. It maintains stable performance even at 90%–110% of rated load, ensuring reliable operation for extended periods.
CSA Security Certification: The motor has passed CSA (Canadian Standards Association) certification, meeting strict safety standards for electrical equipment. This includes protection against electric shock, overheating, and fire, making it safe for use in residential areas or workshops.
IP44 Protection Rating: The IP44 rating ensures the motor is dustproof and protected against water splashes (from any direction). This prevents dust accumulation in the windings and water damage to electrical components, suitable for indoor or semi-outdoor use.
Overload Protection: The motor is equipped with a built-in thermal overload protector. If the current exceeds 13.4A (rated current) or the motor temperature exceeds 120°C, the protector automatically shuts down the motor—preventing burnout or fire.
Cast Iron Casing: The outer casing is made of high-strength cast iron, which has excellent heat dissipation and impact resistance. It can withstand mechanical collisions or heavy loads without deformation, extending the motor’s service life to 6,000+ hours under normal use.
Quality Rolled Steel Shell: The internal stator and rotor use quality rolled steel sheets, which reduce magnetic loss and improve energy efficiency. The sheets are coated with insulation paint to prevent rust and short circuits between layers.
Ergonomic Fixed Base: The motor’s base features four standardized mounting holes, making it easy to install on equipment or a concrete foundation. The base is thickened (8mm) to reduce vibration transmission, minimizing noise (operating noise ≤75dB).
Water Pump Drive: Ideal for powering large-capacity water pumps (e.g., 2-inch centrifugal pumps) in residential water supply systems, irrigation, or water treatment. The high starting torque ensures the pump can lift water from deep wells (up to 15 meters) quickly.
Air Compressor Drive: Used to drive small to medium-sized air compressors (≤50L) in workshops or garages. The 2.2KW power and 3000R/min speed ensure the compressor reaches the required pressure (8–10 bar) efficiently.
Small Machinery Drive: Suitable for powering woodworking machines (e.g., small saws, sanders), metalworking tools (e.g., bench grinders), or agricultural equipment (e.g., small feed mixers). It provides sufficient power for precision machining or mixing tasks.
HVAC System Drive: Used with large fans or blowers in residential or small commercial HVAC (heating, ventilation, and air conditioning) systems. The energy-efficient design reduces electricity costs for year-round operation.
The dual capacitors serve two key roles: (1) The 250μF start capacitor provides extra torque to start the motor quickly, even when under load (e.g., a water pump filled with water); (2) The 50μF run capacitor stabilizes the motor’s power output during operation, improving efficiency and reducing heat generation. This design ensures both easy starting and stable performance.
Yes. The motor requires a generator with a rated power of ≥3KW (to handle the starting current, which is 3–5 times the rated current: 13.4A). Ensure the generator’s output voltage is 220V (single-phase) and frequency is 50Hz to avoid motor damage.
Single-phase motors (this series) use 220V single-phase power (common in households/workshops) and have a dual-capacitor design for starting. Three-phase motors (MS Series) use 380V/415V three-phase power (common in large factories) and have higher efficiency for heavy industrial use. This series is more suitable for small-scale, off-grid, or residential applications.
Replacing the capacitors is simple: (1) Disconnect the motor from power; (2) Open the terminal box (located on the top of the motor); (3) Remove the old capacitors (marked C1 and C2) and replace them with new ones of the same specifications (C1: 50μF/450V, C2: 250μF/30V); (4) Reconnect the wires and close the terminal box. We recommend using capacitors from our official supplier to ensure compatibility.
