A thermal study on small synchronous reluctance machine in automotive cycle

Abstract

Embedded automotive application has one of the harshest environment for electrical machine, especially in terms of thermal requirement. In this study, thermal evaluation of a small synchronous reluctance (Syncrel) machine intended to be used as clutch actuator is presented. A lumped parameter (LP) thermal model was built and validated experimentally. The results of the model subjected to a standardized WLTP cycle shows that the machine is thermally robust and apt for automotive application.
