Abstract: A transient reduced order model (ROM) for electric machines based on singular value decomposition (SVD) is proposed. The ROM generation process starts with computation fluid dynamics (CFD) results of an electric machine model, from which SVD is used to calculate the approximate subspace that the temperature solution belongs to. Then a ROM working in the subspace is created. The ROM is shown to provide very similar results as those from CFD under arbitrary transient loss profiles. The ROM runs orders of magnit…
