In this paper, the air-gap flux density characteristics of three permanent-magnet vernier machines (PMVMs) with different rotor-PM topologies, i.e., surface, Halbach and spoke-array types are analyzed and compared. The investigated machines share the same stator configuration characterized by fractional-slot concentrated windings and multitooth split ...

The band structures and density of states of 77 infintely large conjugated hydrocarbon polymer networks are calculated with HMO. A general rule for predicting whether the HOMO-LUMO band gap is zero or non-zero is proposed for an arbitrary hydrocarbon polymer network with periodic structure. The effects of bond alternation and of conjugate branching are

Influence of magnet size and rotor topology on the air-gap flux density of a radial flux PMSM
2013 IEEE International Conference on Industrial Technology (ICIT), 2013When designing the rotor of a radial flux permanent magnet synchronous machine (PMSM), one key part is the sizing of the permanent magnets (PM) in the rotor to produce the required air-gap flux density. This paper focuses on the effect that different coefficients have on the air-gap flux density of four radial flux PMSM rotor topologies.
