Comprehensive Study of a FMaSynRM for forklift applications by FEM using open-source platform considering both electromagnetic design and modelling aspects

Abstract

A comprehensive study of a ferrite magnet assisted synchronous reluctance machine (FMaSynRM) for the forklift applications by using open-source platform is introduced in detail in this paper including both modelling and electromagnetic design aspects. On the electromagnetism modelling side, this paper uses Elmer as the core and combines other open-source packages covering the preprocessing, solving, and postprocessing sections to build the finite element model of the FMaSynRM. On the electromagnetic design side of the FMaSynRM, this paper mainly discusses the single-double layer winding arrangement, rotor topology, and demagnetization performance. And the power, efficiency, and current maps of the finalized machine at different speeds and loads are estimated by the finite element method (FEM) using the open-source platform, which takes different control logics into consideration. Finally, the predicted results by FEM are verified by the tested results. The modelling method by using open-source platform and design procedure of the FMaSynRM presented in this paper can also be used in the design of other electrical machine types in the adjustable speed applications.
