Flux-Switching Machine With DC Excitation

IEEE Transactions on Magnetics, 2012
This paper proposes a topology of flux-switching machine with dc excitation to improve the field-weakening capability of flux-switching machines. This dc-excited flux-switching machine preserves the structure of typical flux-switching permanent-magnet machines while replacing the permanent magnets with dc field windings. The combined advantages of this

Flux-Regulation Theories and Principles of Hybrid-Excited Flux-Switching Machines

IEEE Transactions on Industrial Electronics, 2015
A hybrid-excited flux-switching (HEFS) machine was proposed by reducing the permanent-magnet (PM) length of an original flux-switching PM machine and introducing a set of field windings into the saved space. According to the PM locations, three typical topologies of HEFS machines emerged, namely, PM-Top, PM-Bottom, and PM-Middle, respectively.

Hybrid-Excited Flux-Switching Permanent-Magnet Machines With Iron Flux Bridges

IEEE Transactions on Magnetics, 2010
Hybrid-excited machines utilize the synergies of permanent magnet (PM) and wound field machines. Flux-switching PM machines have emerged as an attractive machine type due to the fact that the excitation sources are located in the stator allowing a simple robust rotor whilst providing high torque density. This paper proposes topologies of hybrid-excited

An Axial-Flux Hybrid Excitation Flux-Switching Machine

Advanced Materials Research, 2011
A flux switching permanent magnet (FSPM) machine has the advantage of high power density, high torque density, inherently sinusoidal back EMF, stable structure, and the disadvantage of magnetic field uncontrollable. This paper proposes a novel axial-flux hybrid excitation flux-switching (AFHEFS) motor, which offers three phase symmetrical sinusoidal ...
