Abstract

In some applications electric motors operate only for a very short period of time. Thermal designs of such motors are extremely important to optimize system weight and size. This paper discusses transient thermal performance of a short-duty rated motor. An analytical study shows that the quality of impregnation plays a significant role in transient performance. Thermal protection with temperature sensors will not be reliable due to delays in temperature measurement, and a predictive protection is essential. The analysis is confirmed by 2-dimentional finite element analysis and prototype motor testing.
