Product Introduction of 90KW 4-Pole 1400rpm Three-Phase Induction Motor

This product is a 90KW 4-pole 1400rpm three-phase induction motor, operating stably based on the principle of electromagnetic induction. When three-phase alternating current is supplied to the stator windings, a rotating magnetic field is generated. This field cuts the rotor conductors, inducing electromotive force and induced current in the rotor. Driven by electromagnetic force, the rotor rotates steadily, realizing efficient conversion of electrical energy to mechanical energy. Its rotor speed is slightly lower than the 1500rpm synchronous speed, ensuring smooth and consistent power output for medium-speed industrial scenarios.

Structurally, it adopts a balanced rigidity design to适配 medium-speed operation requirements. The stator is laminated with high-grade silicon steel sheets using optimized technology, which reduces iron loss and enhances magnetic conductivity. The windings are made of Class F insulation materials and manufactured via precision winding processes, effectively improving insulation performance and heat resistance, supporting continuous operation under long-term high-load conditions. The rotor features a cast aluminum squirrel-cage structure, with conductor bars and end rings integrated by casting, boasting high mechanical strength, moderate rotational inertia and excellent starting performance, suitable for intermittent and frequent start-stop working conditions.

The performance parameters are fully optimized to meet industrial medium-speed operation demands. With a rated power of 90KW and rated speed of 1400rpm, the rated torque reaches 612N·m, and the scientific ratio of starting torque to maximum torque ensures stable start-up under heavy-load conditions. The motor complies with GB1 level energy efficiency standard, with a power factor of ≥0.87, and both no-load loss and load loss are strictly controlled, achieving significant energy-saving effects in long-term operation.

It is equipped with a cast iron machine base, which provides strong shock resistance and efficient heat dissipation. High-precision rolling bearings are adopted, and the lubrication system is optimized to extend the service life of the motor. The protection level is optional IP54/IP55, adapting to dusty, moderately humid and other complex industrial environments. Widely applicable to medium-speed equipment such as water pumps, conveyors, mixers and compressors, it serves as a high-efficiency, stable and reliable power core for modern industrial production.
