High Voltage Ribbed Cold Motor is a high-performance cast iron casing motor. The motor is a fully enclosed air-cooled motor. The newly designed cast iron casing has fins that conform to the air flow direction and have excellent heat dissipation during motor operation. This series of motors has an external external fan and the fan is made of steel.

The High Voltage Ribbed Cold Motor rotor is a squirrel-cage structure with a state-of-the-art copper cage rotor that ensures greater load on the smooth running of the motor. Moreover, the rotor copper strip is processed by the in-tank fastening process, and thus has high reliability.

The High Voltage Ribbed Cold Motor stator features an external press fit. The stator winding adopts Class F insulation material and anti-corona material. The winding end is fixed by special lashing process, which is firm and reliable. The whole stator is treated with vacuum pressure immersion paint F-grade solventless paint (VPI). Thus, the motor has excellent and reliable insulation properties and moisture and impact resistance.
