Design optimization analysis on the performance of BLDC motors on electric bicycles

Abstract Optimal design results in maximum motor performance. This type of BLDC has undergone innovations such as surface-mounted permanent magnet (SPM) with variants as: radial magnet, rectangular and bread-loaf. The position the outer rotor is a that commonly applied to electric bicycles. attached side body allows for superior torque In this paper, we present an analysis on bicycle been implemented. used uses SPM geometry power 500W. Parameter changes made are slot depth, tooth width, comparing basic Halbach array using 2 3 magnets. Changes these parameters have impact power, torque, speed, efficiency.
