dc.description.abstract Finite element analysis of winding losses in electrical machines can be computationally uneconomical. Computationally lightermethods often place restrictions on the winding configuration or have been used for time-harmonic problems only. This paperproposes a domain decomposition type approach for solving this problem. The slots of the machine are modelled by their impulseresponse functions and coupled together with the rest of the problem. The method places no restrictions on the winding and naturallyincludes all resistive AC loss components. The method is then evaluated on a 500 kW induction motor. According to the simulations,the method yields precise results 70–100 faster compared to the established finite element approach. en
