Abstract:In this paper, doubly salient brushless DC machines (DS-BLDCM) with different rotor pole arcs are compared in terms of their generating and motoring operation. For generating operation, comparison of output power, output voltage and magnetic flux distribution with different rotor pole arcs are obtained by finite element analysis (FEA). For motoring operation, comparison of output torque, torque ripple and efficiency based on basic control scheme are obtained. The analysis results indicate that when the rotor p… 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.
