Product Introduction of 90KW 2-Pole 2800rpm Three-Phase Induction Motor

This product is a 90KW 2-pole 2800rpm three-phase induction motor, which relies on the principle of electromagnetic induction for stable operation. When three-phase alternating current is introduced into the stator windings, a high-speed rotating magnetic field is generated instantly. This magnetic field cuts the rotor conductors, inducing electromotive force and induced current in the rotor. Driven by electromagnetic force, the rotor rotates rapidly, realizing efficient conversion of electrical energy to mechanical energy, with the rotor speed slightly lower than the synchronous speed of 3000rpm, ensuring smooth and reliable power output.

Structurally, it adopts a high-rigidity design to adapt to high-speed operation. The stator is made of high-quality silicon steel sheets with optimized lamination technology, which minimizes iron loss and improves magnetic conductivity. The windings use Class F insulation materials, combined with precision winding process, effectively enhancing insulation performance and heat resistance, enabling the motor to work continuously under high-load conditions. The rotor adopts a cast aluminum squirrel-cage structure, with integrated casting of conductor bars and end rings, featuring high mechanical strength, low rotational inertia and excellent starting performance, suitable for frequent start-stop working conditions.

The performance parameters are fully optimized to meet industrial high-speed operation needs. With a rated power of 90KW and rated speed of 2800rpm, the rated torque reaches 306N·m, and the ratio of starting torque to maximum torque is scientifically matched to ensure stable start-up under medium-load conditions. The motor complies with GB1 level energy efficiency standard, with a power factor of ≥0.88, and both no-load loss and load loss are strictly controlled, achieving remarkable energy-saving effects.

It is equipped with a cast iron machine base for strong shock resistance and good heat dissipation. High-precision rolling bearings are adopted, and the lubrication system is optimized to extend service life. The protection level is optional IP54/IP55, adapting to dusty and moderately humid industrial environments. Widely used in high-speed equipment such as fans, compressors and centrifugal pumps, it is a high-efficiency and stable power core for modern industrial production.
