Switched reluctance motors (SRMs) have been gaining increasing popularity and emerging as an attractive alternative to traditional electrical motors in hybrid vehicle applications due to their simple structure, ruggedness, ability of fault-tolerance, extremely high-speed operation, high power density, and low manufacturing cost. However, large torque ripple and acoustic noise are well-known as their major disadvantages. This thesis presents a novel five-phase 15/12 SRM which features higher power density, very low level of vibration with flexibility in controlling the torque ripple profile. This design is classified as an axial field SRM, hence it needs 3-dimensional finite-element analysis model. Nonetheless, an alternative 2-dimensional model is developed and simulated using FEA software (MagNet) in order to analyze the proposed model. The findings from the simulation is scrutinized and analyzed to realize various design features along with performance of the model. The finding in reference to the proposed axial field model is then compared with existing radial field models to validate its performance improvement. The manufacturing issues were addressed to prove its feasibility and cost effectiveness in conjunction with its assembly competences. Taking all the aspects into account superiority of new model's efficiency is comprehended to justify its application in HEV application.
