摘要：
Different from traditional V-shaped permanent magnet (VPM) structure that shows one pole-pair field distribution with N and adjacent S magnets, the V-shaped consequent-pole permanent magnet (VCPM) configuration has one pole-pair field distribution with the magnet and adjacent rotor iron. In order to further investigate the difference of torque performance of the VPM and VCPM machines due to their different field distribution, the Maxwell Stress Tensor (MST) method is employed to identify and quantify their torque contributions of the air-gap field harmonics. It reveals the difference of the torque contributions of the main-order and field modulated harmonics on the two machines, which confirms a fact that the VCPM machine shows a higher torque capability due to its significant improved torque component of the field modulated harmonics. Furthermore, the influences of the key design parameters on air-gap field modulation effect are studied and summarized. Finally, a VCPM prototype is manufactured, and some tested results are conducted, which confirms the reliability of the theoretical analysis and finite element simulations. ©2024 Chin.Soc.for Elec.Eng.
