Product Introduction of 55KW 2-pole 2800rpm Three-phase Asynchronous Motor

This 55KW 2-pole 2800rpm 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, serving as a reliable power core for heavy-duty industrial equipment.

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

Its core performance parameters meet high industrial standards. Rated power 55KW, rated pole number 2, synchronous speed 3000rpm, rated speed 2800rpm with a reasonable slip ratio for smooth and powerful output. Rated voltage 380V, rated frequency 50Hz, power factor ≥0.90, efficiency ≥93.5%, complying with high-efficiency motor energy efficiency norms to cut enterprise energy costs. Locked-rotor torque multiple ≥1.9, maximum torque multiple ≥2.4, with strong overload capacity to handle sudden load fluctuations. Default protection class IP54, customizable to IP55, with good dustproof and waterproof performance, adapting to dusty, humid and other complex industrial environments.
