Tóm tắt

Thermal constraints place significant limitations on how electric motors ultimately perform. Without the ability to remove heat, the motor cannot operate without sacrificing performance, efficiency, and reliability. Finite element analysis and computational fluid dynamics modeling approaches are being increasingly utilized in the design and analysis of electric motors. As the models become more sophisticated, it is important to have detailed and accurate knowledge of the motor material and material interface thermal properties for the expected temperature range of the motor. In this work, we provide an overview of research to improve measurement accuracy for low thermal conductivity materials representative of motor winding materials at temperatures up to 200 degrees C.
