Review of multidisciplinary homogenization techniques applied to electric machines

Cost reduction of any design process is always of interest for industries. Simulation work packages tackle this problem since they can quickly provide reliable results that permit detection of critical design issues prior to the prototype phase. A trade-off is then often made between model accuracy and computation speed. In the particular case of electric machines, homogenization techniques are used in order to keep high accuracy while running fast calculations. They are involved in multiple disciplines in which the machine performances are verified such as electromagnetic, mechanical, thermal and acoustic domains. This paper aims at defining whether these homogenization methods can be extended from one discipline to another by reviewing them independently of the physical domain.
