Product Introduction of 200KW 4-Pole 1490rpm Three-Phase Induction Motor

This 200KW 4-pole 1490rpm three-phase induction motor achieves efficient conversion of electrical energy to mechanical energy based on the core principle of electromagnetic induction. When three-phase alternating current is supplied to the stator windings, a rotating magnetic field with a synchronous speed of 1500rpm is instantly generated. This magnetic field cuts the rotor conductors, inducing electromotive force and induced current in the rotor, which drives the rotor to rotate stably under the action of electromagnetic force. Its rotor speed of 1490rpm is slightly lower than the synchronous speed, ensuring smooth and continuous power output for medium-high-speed industrial operations, with low vibration and noise levels.

Structurally optimized for medium-high-speed stability and heavy-load endurance, the motor adopts a balanced high-rigidity integrated cast iron frame. The stator is laminated with high-grade low-loss silicon steel sheets through precision stamping and lamination technology, which effectively minimizes iron loss and enhances magnetic conductivity, further boosting overall operational efficiency. The windings are made of high-quality Class F insulation materials, combined with vacuum impregnation and precision winding processes, greatly improving heat resistance and insulation reliability, enabling long-term continuous full-load operation without insulation breakdown even in high-temperature working environments.

The rotor features a low-rotational-inertia cast aluminum squirrel-cage structure, with conductor bars and end rings integrated by one-time casting. This design ensures high mechanical strength, quick start-up response and excellent dynamic performance, allowing the motor to cope with frequent start-stop and sudden load changes. Key performance parameters are fully optimized: rated power 200KW, rated speed 1490rpm, rated torque up to 1273N·m, and the scientific ratio of starting torque to maximum torque guarantees stable start-up under medium-heavy load conditions. Complying with GB1 energy efficiency standard, it has a power factor of ≥0.88, with strictly controlled no-load and load losses for remarkable energy-saving effects.

Equipped with high-precision sealed rolling bearings and an optimized lubrication system, the motor minimizes friction loss, reduces maintenance frequency and extends service life significantly. The optional IP54/IP55 protection level enables it to adapt to complex industrial environments such as dusty, moderately humid and high-temperature occasions. Widely applied to medium-high-speed equipment like water pumps, air compressors and industrial fans in petrochemical, power generation, metallurgy and manufacturing industries, it serves as a high-efficiency, stable and reliable power core for modern industrial production.
