Abstract

In this study, the optimum
design of a BLDC motor which is used for in-wheel light electric vehicle
propulsion is presented. The optimization work is mainly based on different
slot-pole numbers which give a substantial performance for that certain
application. An outer rotor, 2.5kW, 150V BLDC motor which is widely implemented
in light electric vehicle traction is selected. Finite Element Analysis (FEA)
is of the target motor design is conducted for various slot-pole combinations.
By using the captured design data, the optimized motor is manufactures and
tested. The test and simulation results are compared in order to investigate
the optimization approach

Keywords
