Sažetak

The temperature distribution over the cross-section of an induction motor is calculated at the steady state and transient condition. In order to develop smaller and more efficient electric motors, there is a necessity to carry out more thermal analysis in parallel with the traditional electromagnetic design. It has been found that attention to the thermal design can be rewarded by major improvements in the overall performance. The developed thermal model for Total Enclosed Fan Cooled (TEFC) induction motors is implemented into the design program called Motor-CADTM. The model produced has been experimentally verified by measurements on industrial machines. The obtained results confirm that the developed thermal model is capable of a sufficient degree of accuracy in the thermal design of (TEFC) induction motors.
