An Analytical Model of Concentric Layer Structure for Canned Machines, Part I: Armature Coils

Concentrated coils have been gaining interest for lower copper loss and production cost [1–3]. As to SRMs, all turns are featured by being fixed onto a single tooth. To have a comprehensive analysis, including the use of cans, an analytical model is necessary, in which the magneto-motive force (MMF) distribution is one primary consideration [4, 5]. In this chapter an analytical MMF model is proposed.
