Product Introduction of 132KW 8-Pole 745rpm Three-Phase Induction Motor

This 132KW 8-pole 745rpm three-phase induction motor realizes efficient conversion of electrical energy to mechanical energy based on the core principle of electromagnetic induction. When three-phase alternating current is supplied to the stator windings, a rotating magnetic field with a synchronous speed of 750rpm is instantly generated. This magnetic field cuts the rotor conductors, inducing electromotive force and induced current in the rotor, which drives the rotor to rotate stably under the action of electromagnetic force. Its rotor speed of 745rpm is slightly lower than the synchronous speed, ensuring smooth and continuous power output for low-speed heavy-load industrial scenarios.

Structurally designed for heavy-duty low-speed operations, the motor adopts a high-rigidity cast iron machine base, which provides strong shock resistance and stable operation performance. The stator is laminated with high-grade low-loss silicon steel sheets through precision technology, effectively reducing iron loss and improving magnetic conductivity. The windings are made of Class F insulation materials, combined with vacuum impregnation and precision winding processes, greatly enhancing heat resistance and insulation reliability, enabling long-term continuous full-load operation without insulation failure.

The rotor features a cast aluminum squirrel-cage structure, with conductor bars and end rings integrated by one-time casting, ensuring high mechanical strength, appropriate rotational inertia and excellent starting performance, which can cope with intermittent and frequent start-stop working conditions. Its key performance parameters are optimized: rated power 132KW, rated speed 745rpm, rated torque up to 1690N·m, and the scientific ratio of starting torque to maximum torque guarantees stable start-up under heavy-load conditions. Complying with GB1 level energy efficiency standard, it has a power factor of ≥0.85, with strictly controlled no-load and load losses, achieving remarkable energy-saving effects.

Equipped with high-precision sealed rolling bearings and an optimized lubrication system, it minimizes friction loss and extends service life. The optional IP54/IP55 protection level adapts to complex industrial environments such as dusty and moderately humid occasions. Widely applied to low-speed heavy-load equipment like heavy-duty conveyors, ball mills, crushers and large pumps, it serves as a reliable and high-efficiency power core for modern industrial production.
