1.5KW 6-Pole Three-Phase Induction Motor Introduction

This 1.5KW three-phase induction motor adopts a 4-pole configuration with 1400 RPM rated speed (close to 1500 RPM synchronous speed at 50Hz). Based on electromagnetic induction, it drives a squirrel-cage rotor via a rotating magnetic field. With IE2/IE3 efficiency, IP54 protection and Class F insulation, it’s durable for light-to-medium industrial, agricultural and municipal applications.

This 1.5KW three-phase induction motor is a reliable industrial drive unit, characterized by a 6-pole configuration and a rated speed of 900 RPM—closely approaching the 1000 RPM synchronous speed under 50Hz three-phase alternating current (AC) power supply. Its operation relies on the core principle of electromagnetic induction: three-phase AC supplied to stator windings generates a uniform rotating magnetic field (RMF), which cuts rotor conductors to induce electromotive force (EMF) and eddy currents. The interaction between these currents and the RMF produces electromagnetic torque, driving the rotor to rotate asynchronously with a low slip ratio (3%-5% at rated load), ensuring stable power transmission.

Structurally, it adopts a rugged cast-iron frame with IP54 protection class, offering dustproof and waterproof performance for harsh environments. The stator features high-purity oxygen-free copper windings encapsulated in Class F insulation (155℃ thermal endurance), minimizing copper loss and preventing insulation breakdown. The 6-pole rotor uses a die-cast aluminum squirrel-cage structure, ensuring high mechanical strength and low maintenance, paired with precision sealed deep-groove ball bearings lubricated by lithium-based grease to reduce frictional loss.

Key performance parameters meet industrial demands: rated voltage 380V (50Hz), rated current ~3.6A, power factor ≥0.83, starting torque 1.7x rated torque, and maximum torque 2.1x rated torque. Compliant with IE2/IE3 efficiency standards, it reduces energy consumption with noise ≤72dB at 1m. Suitable for light-to-medium-duty applications, it powers mechanical processing equipment, irrigation pumps, ventilation fans, and municipal water treatment devices, supporting horizontal/vertical mounting. Regular insulation testing (≥2MΩ at 500V DC) and maintenance extend its service life, making it a cost-effective solution for diverse industries.
