How Much Does The Temperature Rise Of The Motor Winding Have To Do With The Structural Parts?

              How much does the temperature rise of the motor winding have to do with the structural parts?

Motor winding temperature rise level state, more from the motor type test and motor application process found in, in the batch motor quality evaluation, personalized winding heating, may be the corresponding heating individual factors, and batch uniform heating performance may be design, manufacture or use of a link of the problem, should be carried out comprehensive inspection and analysis.

Two high-voltage motors of the same specification produced by a motor factory, in the type test link, it was found that the temperature rise level of one motor winding was very good, but the other motor was seriously heated, and the technical analysis may be related to the structural parts of the motor.

From the actual motor quality case data statistical analysis, the error of structural parts in the motor manufacturing process will not have much impact on the individual temperature rise level of the motor, that is, when only the windings of individual motors in the same batch of motors deviate from the temperature rise level, the problem of structural parts is less likely, and it should be inclined to analyze the influence of impregnation and unexpected factors in the motor manufacturing process.

According to the previous motor quality failure cases, when the insulation treatment effect of the motor is not good, such as the preheating before dipping is not in place, the temperature during the drying process is not suitable, and the pressure during the vacuum pressure dipping process does not meet the requirements, etc., it may lead to the deterioration of the temperature rise level of the motor winding; Some motors can improve their temperature rise level through secondary immersion, and most of the windings, because the surface of the winding is blocked after primary dipping, almost no change in the insulation structure inside the winding during secondary immersion, so it will not play a big role in the temperature rise of the motor.

Therefore, the insulation treatment process of motor windings is listed as a key process of quality control in any motor manufacturer, and it is processed in strict accordance with reasonable and effective insulation treatment technology, which is a necessary condition for ensuring the temperature rise level of the motor.

Of course, in addition to the influence of the insulation treatment process of the winding, any factor affecting the normal heat dissipation conditions of the motor may cause the temperature rise level of the motor to change, such as the unobstructed air path, the damage or lack of ventilation components, etc. How to ensure the quality level of products through strict quality control is a very key management measure.
