Abstract

Permanent magnet synchronous motors are widely accepted in automotive applications. The high torque density,
high rotational speed with maximum efficiency in electric vehicle applications is technically challenging for motor design.
However, these machines are expensive and difficult to work at high-temperature harsh environment due to permanent magnets
demagnetisation features. Alternatively, switched reluctance motors can provide similar output characteristics and a wider
speed. Thus these are considered to be more fault tolerant and more reliable. This study proposes a 20 kW, three-phase
switched reluctance motor and analyse its overall performance and harmonic contents. The study is conducted by optimising
the slot filling factor, excitation voltage and switching sequence of an asymmetrical half bridge converter. A finite element model
is used to predict the core and copper losses and other influencing parameters. Simulation results are presented and analysed
the effectiveness of the proposed switched reluctance motor (SRM).
