Design and Modifications of Rotor Flux Barrier in Synchronous Reluctance Motor for E-Bike

Electric bicycles have become progressively popular due to their environmentally friendly and cost-effective nature. However, choosing a suitable motor is very much needed to attain better performance and energy efficiency. This research paper explores the design and modification of rotor flux barrier in synchronous reluctance motor (SynRM) for an electric bicycle by comparing its Hyperbolic-curve and Hyperbolic-polyline rotor designs. The aim of this study is to determine which design produces more efficiency in terms of power consumption and performance. Both designs were analyzed using finite element analysis, and their performance was evaluated through simulations by Ansys rmxprt. The results revealed that the hyperbolic-curve design had a higher efficiency and better performance compared to the hyperbolic-polyline design. This suggests that the hyperbolic-curve design is a better choice for electric bicycles.
