Abstract

Air gap in one of the factor need to consider before designing a machine. It plays a major part in the machine operation and greatly affects the motor performances. As a result different air gap for designing Dual Rotor Hybrid Excitation Machine (DRHEFSM) are being investigated. 0.4mm air gap has been chosen because of the influence of the existing Hybrid Excitation Flux Switching Machine (HEFSM) that used total 0.8mm air gap and successful in performing the machine operating principle. Furthermore, the machine also successfully obtaining good result in motor torque and speed. Total 0.8mm air gap are being used for the new design, 0.4mm for the outer rotor air gap and 0.4mm for the inner rotor air gap. Besides that, 0.3mm and 0.5mm air gap are being investigated in order to analyse the optimum air gap for the design machine. Flux characteristic, cogging torque and back-emf of each air gap design are the parameter that being analyse and compared in determining the best air gap design. As conclusion, the 0.4mm air gap successfully follow the operating phase of three-phase machine, obtaining lowest cogging torque and own small harmonic back-emf.
