Brushless dc motor insulation all levels have why to distinguish? | | low voltage brushless dc motor brushless dc motor in the south of anhui

For brushless dc motor insulation materials, insulation level, the higher its resistance to voltage value is higher? What's the difference between each grade? With these two problems, today brushless dc motors in the south of anhui small make up take you to understand the brushless dc motor insulation class related knowledge. Low voltage brushless dc motor insulation materials insulation are rated E, B, F, H, C, etc. , their insulation is roughly the same level, such as can withstand 5 kv voltage withstand test, so can't simply say insulation level is higher, the insulation resistance voltage value is higher. The difference lies mainly in their thermal insulation grade level, so strictly speaking should be referred to as insulating materials heat resistance level. According to the above order, in the heat level higher and higher, it can allow the highest temperature see chart. Ordinary brushless dc motor used B and F two grades, the use of the individual high class H. Existing a lot of data in brushless dc motor has direct use of brushless dc motor heat temperature numerical said its level, such as insulation level 155. Next brushless dc motor, brushless dc motor in the south of anhui small make up take you to understand what is the rise of temperature of the brushless dc motor, please continue to pay attention to the information center for brushless dc motor in the south of anhui.
