High voltage electric motor series adopts foreign advanced technology, combined with the company's own practical experience in producing high voltage motor designed and manufactured. Milestone's high-voltage motors meet the relevant standards of the International Electrotechnical Commission (IEC), its rated frequency is 50Hz, rated voltage is 3KV, 6KV, 10KV, we can also manufacture 60Hz and other voltage high-voltage motors according to customer requirements.
Introduction of the Cooling method of the different high voltage motor series:
| Model | Cooling | IP Grade | Cooling Structure |
| Y,YX,YR | Open IC01 | IP23 | Ventilator hood on top Without ventilator on top but ventilation opening on housing side |
| YKS,YRKS | Air/water cooling, enclosed IC81W | IP44/IP54 | Air /water cooler on housing top |
| YKK,YXKK | Air/air cooling, enclosed IC611 | IP44/IP54 | Air /water cooler on housing top |
| YRKK | Air/air cooling, enclosed IC611 | IP44/IP54 | Air /water cooler on housing top |
Structure of High Voltage Motor
1.High voltage motor adopts box structure, and the base is welded into a box by steel plate, which is light in weight and good in stiffness.
2.The stator adopts an external press mounting structure. The stator winding adopts Class F insulating materials and corona resistant materials. The winding end is fixed using a special binding process, which is firm and reliable. The entire stator is treated by vacuum pressure impregnation without solvent paint. The motor has excellent and reliable insulation performance, good mechanical strength, and strong moisture resistance.
3.The squirrel cage rotor has two structures: cast aluminum and copper bar, which are manufactured by advanced and reliable cast aluminum process or welding process.
4.The wound rotor is made of Class F insulating material, which is treated by vacuum pressure impregnation and non solvent paint process, and has undergone accurate dynamic balance verification.
5.The bearings have two types, rolling bearings and sliding bearings. What type is adopted depends on electric motor power and speed. Its protection degree is either IP44 or IP54.
6.The electric motors with rolling bearings have greasing and discharging device, which enable no-stop operation. Special greasingtools are equipped.
7.The terminal box is a sealed structure, generally installed on the right side of the motor, and can also be customized according to user requirements.
