Structural characteristics

This series of motors adopts a box shaped appearance, and the base is welded from steel plates, which makes the motor have the characteristics of good rigidity and light weight. The optimized design of the motor structure also makes the series of motors easy to install and maintain.

The stator and rotor laminations are made by punching low loss non oriented cold-rolled silicon steel sheets.

The stator adopts an external pressure structure, the stator winding adopts F-class insulation material, and the coil end is reliably fixed and tied. After the end wiring of the coil is completed, it needs to undergo inter turn pulse voltage testing and be treated with internationally advanced vacuum pressure impregnation solvent-free paint (VPI) technology.

The wound rotor is made of pure copper bars and uses F-grade insulation material. And after dynamic balance verification, the motor runs smoothly and reliably.

The bearings adopt two structural forms: rolling bearings and sliding bearings, depending on the motor power, usage, and speed.
