摘要
General analytical model is proposed for dual-modulation permanent magnet vernier machines (PMVM) having consequent pole Halbach arrays at both stator slot opening and rotor slot. From the Laplace/Poisson equations of each region, the subdomain model and the solution process for the dual-modulation PMVM are analyzed. Taking 22p/12 s machines as examples, which having two-segment consequent pole Halbach arrays in both the stator and the rotor, the air gap field is obtained by solving the matrix equation. The induced electromotive force and the electromagnetic torque are calculated. The relevant finite element analysis results verify the accuracy of the analytical results. In addition, the optimization results for the Halbach arrays are also presented.
