Design of an asymmetric rotor pole for wound field synchronous machines
This study proposes a novel asymmetric rotor pole design for wound field synchronous machines (WFSMs), which can achieve high saliency ratio and also low torque ripple.The key point is the optimal design of the asymmetric rotor pole with the inverse-cosine-shaped (ICS) plus reverse 3 rd harmonic shaping.The asymmetric rotor pole can help to improve
