Description

technical field

[0001] The invention relates to an AC motor, in particular to a ventilation cooling device for the AC motor. Background technique

[0002] AC motors are widely used in various industries, such as steel, electric power, coal, papermaking, pharmaceutical papermaking and other fields. Whether the temperature rise of the AC motor is normal or not is not only related to its working load, but also related to its working system. The selection of motor working system is usually determined according to the working conditions on site. However, in the actual use process, many motors have insulation failures, not because the insulation material is not good, but because the load is too large during operation, the ventilation and cooling effect of the motor is not ideal, causing the maximum temperature of the motor to exceed the maximum allowable value of the winding insulation material , When this limit is exceeded, the insulating material will age and become brittle, g...
