“…For a limited motor volume, determination of split-ratio also enhances electromagnetic torque capability although magnetic and electric loadings are crucial in the first place [17]. According to [18], optimization of magnet fraction, slot opening, airgap length, tooth body width, magnet thickness and number of coil turns result significant improvement in torque performance. A determination of specific airgap thickness should not be ignored as it provides a correlation between the motor torque performance and cost.…”

This paper presents sizing approaches to improve output torque performance in PM motor when partial stator body is removed. As the output torque performance is directly proportional to the electric loading, Q, modification on stator geometry affects the output torque performance and special procedures have to be taken to restore the desired output torque capability. Influences of split ratio, tooth body width, airgap and magnet thickness of magnet in PM motor with asymmetry stator design are carried out and the performance verification are referred to the back-emf, average output torque, torque ripple as well as cogging torque. From the investigation using 2D-Finite Element Analysis, optimum size of tooth body width and optimum number of coil turns result better output torque while other sizing approaches result no significant change as quick saturation took place.
