When phase AB is required to be turned on, only Q1 and Q4 tubes need to be turned on, and other tubes must be kept off.

Insulating materials are particularly susceptible to high temperatures and accelerate aging and damage.
Different insulation materials have different heat-resistant functions, and electrical equipment using different insulation materials has different high-temperature resistance capabilities. Therefore, the general electrical equipment regulates the maximum temperature of its operation. According to the ability of different insulation materials to withstand high temperatures, seven allowable maximum temperatures are specified for them, arranged Household Motors Suppliers https://www.chinakxdq.com/ according to temperature: Y, A, E, B, F, H, and C. Their allowable operating temperatures are: 90, 105, 120, 130, 155, 180, and 180 ° C. Therefore, Class B insulation clarifies that the insulation heat-resistant temperature selected by the generator is 130 ° C.
The user should ensure that the generator’s insulation material does not exceed the temperature capability when the generator is operating to ensure the normal operation of the generator. Insulation material with insulation class B is mainly made of mica, asbestos, glass fiber by organic glue or impregnation. For example, add 155 degrees F of your motor insulation and 80 degrees of B temperature rise, then the operating environment temperature of your motor should be less than 155-80 = 75 degrees.
