Abstract:Φ Abstract --The macro air-gap element and its torque formulation were proposed earlier by Abdel-Razek et al. for modeling electrical machines with an annular air-gap. This paper extends the existing formulation for force calculation in the finite element model incorporating a two-dimensional Cartesian macro air-gap element. The new formulation can be useful for force or torque calculation of some special electric machines with a flat air-gap such as linear and axial flux machines. For validation purpose, the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
