Product Introduction of 45KW 2-pole 2800rpm Three-phase Asynchronous Motor

This 45KW 2-pole 2800rpm three-phase asynchronous motor relies on the electromagnetic induction principle to achieve efficient electromechanical energy conversion. Three-phase AC applied to stator windings generates a rotating magnetic field; the field cuts rotor bars to induce electromotive force and current, and the generated electromagnetic torque drives the rotor to rotate. The rotor always runs at a speed lower than the synchronous speed, featuring stable power output and high energy conversion efficiency, which is widely recognized in industrial fields.

In structural design, it adopts premium components to ensure durability and reliability. The stator is laminated with cold-rolled silicon steel sheets to minimize iron loss and enhance energy-saving performance. The windings use high-strength electromagnetic wires, processed via vacuum pressure impregnation and curing, reaching Class F insulation to offer excellent heat and moisture resistance. It adopts a cast-aluminum squirrel-cage rotor with small moment of inertia and excellent starting performance, adapting to frequent start-stop working conditions. The cast iron frame has high rigidity and good shock absorption; the integrated end cover and bearing seat ensure high coaxiality, effectively reducing operation vibration and noise.

Its core performance parameters are excellent and meet industrial high standards. Rated power is 45KW, rated pole number 2, synchronous speed 3000rpm, rated speed 2800rpm with a reasonable slip ratio for smooth and powerful power transmission. Rated voltage 380V, rated frequency 50Hz, power factor ≥0.89, efficiency ≥93%, complying with high-efficiency motor energy efficiency norms to cut enterprise energy costs. Locked-rotor torque multiple ≥1.8, maximum torque multiple ≥2.3, with strong overload capacity to cope with sudden load fluctuations. Default protection class is IP54, customizable to IP55, with good dustproof and waterproof performance, suitable for dusty, humid and other complex working environments.

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