The YR series of high-voltage three-phase asynchronous motors adopt anti-corona coil design and secondary impregnation of rotor windings, featuring excellent heat dissipation, compact structure, light weight, good rigidity and strong practicality.

【 Product Description 】

The YR series of high-voltage three-phase asynchronous motors are products developed by our company in response to the demands of industries such as cement and steel mills. They mainly have the following features:

1. The motor base adopts a box structure welded with steel plates, which is light in weight and has good rigidity.

2. By optimizing the electromagnetic design scheme, adopting anti-corona coil design and manufacturing, applying the rotor winding secondary impregnation process, rotor winding fixation process, "double impregnation and double drying" process for the collector ring part, and the application of vacuum pressure impregnation (VPI) equipment, the motor insulation grade has reached F and H class insulation, ensuring safety and reliability.
