Product Introduction of 45KW 4-pole 1400rpm Three-phase Asynchronous Motor

This 45KW 4-pole 1400rpm three-phase asynchronous motor realizes high-efficiency electromechanical energy conversion based on the electromagnetic induction principle. Three-phase alternating current is input into stator windings to generate a rotating magnetic field; when the magnetic field cuts rotor conductors, induced electromotive force and current are produced, and the generated electromagnetic torque drives the rotor to rotate. The rotor speed is permanently lower than the synchronous speed, featuring stable operation, high conversion efficiency and strong adaptability, which is a reliable power core for industrial equipment.

In structural design, it adopts high-quality components and sophisticated craftsmanship to ensure stable operation in long-term work. The stator is laminated with cold-rolled silicon steel sheets to minimize iron loss and improve energy-saving effect. The windings use high-strength electromagnetic wires, treated by vacuum pressure impregnation and high-temperature curing, reaching Class F insulation grade with excellent heat resistance, moisture resistance and insulation stability. It adopts a cast-aluminum squirrel-cage rotor with small moment of inertia and excellent starting performance, suitable for frequent start-stop working conditions. The cast iron frame has high rigidity and good shock absorption performance; the integrated design of end cover and bearing seat guarantees high coaxiality, effectively reducing operation vibration and noise.

Its core performance parameters are excellent and meet high-efficiency industrial standards. Rated power is 45KW, rated pole number 4, synchronous speed 1500rpm, rated speed 1400rpm with reasonable slip ratio for smooth and powerful power output. Rated voltage 380V, rated frequency 50Hz, power factor ≥0.89, efficiency ≥93%, complying with national high-efficiency motor energy efficiency requirements to reduce enterprise energy consumption. Locked-rotor torque multiple ≥1.8, maximum torque multiple ≥2.3, with strong overload capacity to cope with sudden load fluctuations. The default protection grade is IP54, customizable to IP55, with good dustproof and waterproof performance, adapting to dusty, humid and other complex industrial working environments.

Widely applicable to fans, water pumps, conveying machinery, machine tools and other equipment, it supports multiple installation modes such as B3 and B5. With no brush wear, it has the advantages of convenient daily maintenance and long service life, providing stable and continuous high-quality power support for industrial production.
