A Novel Stator-PM Consequent-pole Dual Stator/Rotor Armature Winding Flux Modulated Machine for Multi-Torque Components

This paper proposes a novel hybrid excitation alternate stator PM dual stator/rotor armature winding vernier machine with the DC-biased current. Due to the both armature windings and alternate stator PM interact with each other, this proposed machine contains six torque components. Compared with traditional stator permanent magnet machines and flux modulated machines, this machine makes full use of the space in rotor the cavity, giving full play to the flux modulation effect. This digest will introduce the topology of the machine and its operating principles, and then the electromagnetic characteristics will be analyzed by finite element analysis (FEA).
