SUMMARY In order to reduce the computation time and the memory resources required to solve an electromagnetic field problem, model order reduction approaches can be applied to reduce the size of the linear equation system obtained after discretisation. In the literature, the POD is widely used in engineering. In this paper, we propose to apply the POD in the case of a finite element problem accounting for the movement. The efficiency of this method is evaluated by considering an electrical motor and by comparing with the full model in terms of computational time and accuracy. Copyright © 2014 John Wiley & Sons, Ltd.
