2.2KW 2-Pole Three-Phase Induction Motor Introduction

This 2.2KW three-phase induction motor is a high-efficiency industrial drive component, featuring a 2-pole configuration and a rated speed of 2800 RPM—closely approaching the 3000 RPM synchronous speed under 50Hz three-phase alternating current (AC) power supply. Its core operation adheres to the principle of electromagnetic induction: when three-phase AC is supplied to the stator windings, a uniform rotating magnetic field (RMF) is generated, with rotational speed inversely proportional to the number of pole pairs. The RMF cuts the rotor conductors, inducing electromotive force (EMF) and eddy currents, and the interaction between these induced 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 and efficient power transmission.

Structurally optimized for durability and performance, the motor adopts a rugged cast-iron frame with IP54 protection class, providing excellent mechanical rigidity, dustproof, and waterproof capabilities to adapt to harsh industrial environments. The stator is equipped with high-purity oxygen-free copper windings encapsulated in Class F insulation material, boasting a thermal endurance temperature of 155℃, which minimizes copper loss and prevents insulation breakdown. The 2-pole rotor features a die-cast aluminum squirrel-cage structure, ensuring high mechanical strength, low rotational inertia, and minimal maintenance needs, paired with precision sealed deep-groove ball bearings lubricated by high-temperature lithium-based grease to reduce frictional loss.

Key performance parameters are calibrated for industrial applicability: rated voltage 380V (50Hz), rated current approximately 4.5A, and a rated power factor of ≥0.87. It delivers a starting torque of 1.8 times the rated torque for reliable startup under light-to-medium loads, and a maximum torque of 2.2 times the rated torque to cope with occasional load fluctuations. Compliant with IE2/IE3 efficiency standards, it reduces energy consumption with noise emission ≤75dB at 1m. Widely used in mechanical processing, HVAC systems, and fluid engineering, it supports horizontal/vertical mounting, offering a cost-effective and reliable power solution with extended service life via regular maintenance.
