The purpose of this paper is to investigate both the torque ripple reduction technique and influences of mechanical tolerance on the performances of a novel dual-stator 6/4 flux-switching permanent magnet machine. To minimize the torque ripple, step skew designs are studied to determine the optimal step number and step skew span angle. In addition, three common rotor mechanical tolerance deviation...
The goal of this paper is to propose a novel concept of permanent magnet machine with integrated airfoil-shaped rotor that can perform compression action. Electrically driven conventional compressor systems need electric machines as prime movers to provide mechanical energy to rotate the compressor. The proposed novel integrated permanent magnet machine system synthesizes both an electric machine...
The purpose of this paper is to propose a novel flux-switching permanent magnet motor with an integrated airfoil-shaped rotor. Some of the conventional axial-flow compressor systems need an electric motor to provide mechanical energy input to the compressor. The proposed novel flux-switching motor-compressor can integrate both an electric motor and an axial-flow compressor into a single entity and...
This paper presents the study on a novel dual-stator 6/4 flux-switching permanent magnet (FSPM) machine for high-speed applications. Three different alternative topologies of dual-stator 6/4 FSPM machines are proposed and their performances regarding flux linkage, back electromotive force (back-EMF), torque density, and manufacturability are compared to the same specification of 10 kW and 15,000 rpm...
This paper presents an analytical method to realize even order harmonic elimination in flux-switching permanent magnet machines. The proposed method enables the calculation of total offset angle of flux linkages, taking into account an offset angle of stator slot and rotor poles. The 6-slot, 12-slot, and dual structure flux-switching permanent magnet machines are analyzed using the proposed method...
