description Vernier Permanent magnet (VPM) motor has the advantages of compact structure, high power density,and the characteristic of offering high torque at low speed, is suitable for the direct drive applications of wind power generation, electric vehicles and urban railway system. This paper proposes consequent-pole permanent-magnet (CPPM) structure for the aim of saving rare earth resources. CPPM structure employs iron-pole to replace half PM poles. In this paper, two methods are introduced to analyze the motor:Analytical method and equivalent magnetic network method. At this paper, analytical method is validated its accuracy, an analytical model is established for Consequent-pole Vernier PM (CPVPM) machine which could accurately predict the air-gap flux density. The results are reasonable compared with the results from Finite Element Analysis (FEA). At the future work, the nonlinear varying-network magnetic circuit (NVNMC) modeling method will be adopted for CPVPM motor to calculate related electromagnetic performances. The basic theory of this method is to separate the model of CPVPM machine into different elements reasonably; thus, the reluctances and magnetomotive force (MMF) sources in each element can be got. By applying this method and comparing with FEA it verifies that NVNMC can save plenty of time for the original design of machine and is more convenient than FEA.
