Contribution of End-Winding Proximity Losses to Temperature Variation in Electromagnetic Devices
Operating efficiency and carbon footprint are vital considerations for automotive and aerospace applications of motors, transformers and other wound components. Paper deals with important issue of AC winding loss with particular focus on end-winding region. A method of scaling AC winding loss with temperature is proposed. This unique loss-scaling technique is particularly important in accurate and computationally-efficient thermal design for state-of-the-art components. Work provides better understanding of AC winding phenomena and is being used in other projects, e.g. Clean Sky "ELETAD" (No. 267322, €1.9M, 2010-5) and "HERRB" (No. 296693, €524k, 2011-4), and EPSRC "VESI" project (EP/I038543/1, £3.15M, 2011-5).
