Product Introduction of 160KW 4-Pole 1490rpm Three-Phase Induction Motor

This 160KW 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.

Structurally optimized for medium-high-speed stability, the motor adopts a balanced rigidity design that combines operational robustness and lightweight performance. The stator is laminated with high-grade low-loss silicon steel sheets through precision stamping and lamination technology, which effectively reduces iron loss and enhances magnetic conductivity. The windings are made of 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 under high-temperature conditions.

The rotor features a low-rotational-inertia cast aluminum squirrel-cage structure, with conductor bars and end rings integrated by one-time casting, ensuring high mechanical strength, quick start-up response and excellent dynamic performance. Its key performance parameters are fully optimized: rated power 160KW, rated speed 1490rpm, rated torque up to 1022N·m, and the scientific ratio of starting torque to maximum torque guarantees stable start-up under medium-heavy load conditions. Complying with GB1 level energy efficiency standard, it has a power factor of ≥0.88, with strictly controlled no-load and load losses, achieving remarkable energy-saving effects in long-term medium-high-speed operation.

Equipped with a cast iron machine base with enhanced heat dissipation ribs, it boasts excellent shock resistance and efficient heat dissipation capacity. High-precision sealed rolling bearings and an optimized lubrication system minimize friction loss, reduce maintenance frequency and extend service life. The optional IP54/IP55 protection level adapts to complex industrial environments such as dusty and moderately humid occasions. Widely applied to medium-high-speed equipment like water pumps, air compressors and industrial fans in petrochemical, power and manufacturing industries, it serves as a high-efficiency, stable and reliable power core for modern industrial production.
