This paper presents an innovative thermal modeling method for directly liquid cooled electrical machines used in automotive applications. The proposed thermal modeling method is based on a combination of analytical finite elements and computational fluid dynamics methods. The methodology used enables fast simulation results which are necessary during the concept development of electrical machines, where high number of concepts and design parameters are needed to be investigated. The short simulation time provides the possibility to run transient simulations where thermal behaviour of an electrical machine in a duty cycle needs to be evaluated. The simulation approach is implemented in the form of an application with user friendly interfaces.

Abstract
This paper presents an innovative thermal modeling method for directly liquid cooled electrical machines used in automotive applications. The proposed thermal modeling method is based on a combination of analytical finite elements and computational fluid dynamics methods. The methodology used enables fast simulation results which are necessary during the concept development of electrical machines, where high number of concepts and design parameters are needed to be investigated. The short simulation time provides the possibility to run transient simulations where thermal behaviour of an electrical machine in a duty cycle needs to be evaluated. The simulation approach is implemented in the form of an application with user friendly interfaces.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
