Conventional bearingless permanent magnet motors have magnets on their rotor, and their maximum electric loading performance may be restricted by thermal instability and lack of mechanical integrity. To overcome such drawbacks, a novel bearingless motor with magnets, suspension force windings, and torque windings in the stator is proposed; the proposed motor is called bearingless flux-switching permanent...
The operation principle of an axial flux-switching hybrid excitation synchronous machine (AFHESM) is analyzed and its topology structures are proposed in this paper. After some comprehensive analysis of the operation principle to axial flux electrical machine, flux-switching electrical machine and hybrid excitation electrical machine, the operation principle of AFHESM is given. Combined with some...
This paper investigates the inductance characteristics of a novel 3-phase 12/10 (12-stator-tooth/10-rotor-pole) flux-switching permanent magnet (FSPM) machine with doubly-salient structure based on finite element (FE) analysis. Firstly, the topology and operation principle of the machine are presented. Secondly, the apparent (static) and incremental (dynamic) inductances are defined. Then, the conventional...
