E-Bike Motor Design Based on Analytical and Finite Element Performance Mapping

This paper deals with a design procedure of an electric motor for e-bike. The motor topology is the typical permanent magnet synchronous machine. The study combines a preliminary analytical model and finite element analysis simulation to test different motor geometries. Experimental measures for different supplying conditions are presented. The performance is evaluated both through analytical models and finite element simulations. Some parameters are considered as variables analysing the geometries generated by their combinations. Torque, speed, power, losses and efficiency are mapped in order to map the capabilities in the whole parameter space.
