In recent time, flux switching type of brushless permanent magnet machines has been receiving significant interest, especially for high-speed operation. Primary reason is the simple and robust structure of the rotor due to the fact that the permanent magnets are placed in the stator. In order to achieve best possible performance for particular applications, optimization on electric machines is increasingly...
The high-speed machine design is becoming important due to advantages such as high-power density and small size. Flux-switching permanent magnet (FSPM) machines have a simple rotor design without any windings or PMs, which makes them apt for high-speed operation. A low-pole topology of the FSPM machine is desirable to keep the operational frequency to a minimum. The lowest slot–pole combination for...
The purpose of this paper is to characterize the performance of a novel dual-stator six slot four pole (6/4) flux switching permanent magnet machine. The proposed dual-stator 6/4 topology eliminates even order harmonics in the flux linkage and back electromotive force, which are present in the conventional single stator topology. The resulting back electromotive forces of the proposed dual-stator...
The purpose of this paper is to introduce a novel dual-stator six stator slots four rotor poles flux switching permanent magnet machine that is viable for operation. The conventional six slots four poles topology suffers from asymmetrical flux linkage and severely unbalanced back-EMF, which makes it unfeasible. The proposed dual-stator structure utilizes windings in the second stator to produce a...
