Motor housing information
What are the effects of the thickness of the motor shell on the temperature rise of the motor stator winding?
The shell is the most commonly used metal component in the motor structure, and its weight accounts for 25% of the total weight of the motor. The motor shells produced in the early days of the motor factory were even made of aluminum. In fact, not only the material is different, but also the thickness of the shell, which has a great impact on the use of the motor.
In order to reduce the weight of the motor, the motor has conducted research and experiments, and it is believed that the thickness of the casing has an effect on the overheating temperature of the stator winding of the motor. The research institute prepared two B160 shells with the same specifications and dimensions and thicknesses of 4, 6, and 8mm respectively. They were insulated in the shell with heat resistance class H, and prepared a series of shells with the same structure and thickness of 10mm. . The iron core is pressed into this shell, assembled into a complete motor, and then subjected to standard electrical and thermal tests.
Use mathematical statistics to process the test results. The calculation results show that the correlation coefficient is -1, indicating that there is a precise linear relationship between the thickness of the casing and the overheating temperature of the stator winding. The negative sign indicates that the relationship is reversible. The equation derived from the results of mathematical statistical processing shows the relationship between the stator winding overheating and the thickness of the casing. Namely: Y=101.85-2.65X, where X is the thickness of the shell, mm; Y is the temperature difference between the stator winding and the ambient air (40°C).
According to experimental data, when the thickness of the casing changes, the overheating temperature of the stator winding does not exceed the allowable temperature rise of the H-class insulation. According to the regression equation, the thickness of the casing is reduced by 2mm, and the overheating temperature of the stator winding is increased by 3.3℃. This value is calculated based on the ribbed steel casing. Therefore, the thickness of the housing must be determined according to the specific working conditions of the motor.
