摘要：

This paper proposes a subdomain model for open-circuit field prediction in dual-stator consequent-pole permanent magnet machines. The whole field domain is composed of four types of sub-domains, including magnets, air gaps, slot openings, and slots. The proposed model takes the effect of tooth-tips into account, which can accurately calculate the flux density in slots and cogging torque. The finite-element (FE) model is established, which validates that the proposed subdomain model can quickly and accurately predict the magnetic field distribution and cogging torque in dual-stator consequent-pole permanent magnet machines.
