This paper proposes a new consequent-pole permanent magnet vernier machine (CPMVM), which can be regarded as combination of two conventional CPMVM with opposite polarities. Based on the simplified axial magnetic circuit model, it is verified that proposed reduce unipolar leakage flux. In order to torque ripple and improve output machine, flux barrier placed rotor machine. Then, parameters are o...

In this paper, a co-axial dual-mechanical ports flux-switching permanent magnet (CADMP-FSPM) machine for hybrid electric vehicles (HEVs) is proposed and investigated, which is comprised of two conventional co-axial FSPM machines, namely one high-speed inner rotor machine and one low-speed outer rotor machine and a non-magnetic ring sandwiched in between. Firstly, the topology and operation prin...
