“…Due to the half-wave symmetry proved above, only odd order spatial harmonics appear in Structure I as given in Equation (11) and in Structure IV as in Equation (12). However, both odd and even order spatial harmonics exist in Structure II as in Equation (11) and in Structure III as in Equation (12), where A νi is an intermediate coefficient related to the Λ b , Λ g and θ k .…”

“…f r (θ r ) is further processed with Fourier transform, and θ r is replaced with θ s , as θ r = θ s − ωt/p, the rotor magnetic potential is thus transformed to the stator frame in order to facilitate the analysis of radial force on the stator teeth. Due to the half-wave symmetry proved above, only odd order spatial harmonics appear in Structure I as given in Equation (11) and in Structure IV as in Equation (12). However, both odd and even order spatial harmonics exist in Structure II as in Equation ( 11) and in Structure III as in Equation (12), where A νi is an intermediate coefficient related to the Λ b , Λ g and θ k .…”

“…On the other hand, a priori (prior to optimization) ripple reduction methods are: increasing the number of poles, application of barrier corner fillets [10], use of barrier notch (Figure 2a), and use of asymmetric pole designs [17]. The function of the barrier notch is to further increase rotor reluctance, otherwise, the flux lines would distribute between adjacent slots thus contributing to the loss of torque and consequently increasing the torque ripple.…”

“…One of the inherent disadvantages of the SyRM is the increased torque ripple. The issue can be mitigated with the use of asymmetric rotor poles [17,19] or with rotor or stator skewing [40,41]. The drawback of using skewing in optimization is a prolonged transient calculation (it has to be done for each of the rotor slices, e.g., 5 segment rotor skew will have 5 times longer transient simulation).…”
