Abstract:

A novel flux-switching permanent magnet linear motor(FSPMLM)is proposed for linear direct driving machine tools. First, the two- and three-dimensional topological configuration of the proposed motor is presented; the basic operational principle of the FSPMLM is introduced; and the magnetic fields at the two typical conditions of no-load are analyzed. Secondly, the FSPMLM is analyzed by the two-dimensional finite element method(FEM)to investigate the static electromagnetic characteristics such as flux-linkage, back EMF(electromotive force)and inductance performances. The cogging forces of two kinds of FSPMLMs with different shaped cores are analyzed and compared, and the results show that the cogging force is significantly reduced by using the E-shaped cores. Additionally, based on the co-energy method, the thrust equation is derived and verified by the simulation results obtained by the FEM. Finally, an experimental prototype is used to test the characteristics under open circuit and load conditions. The simulation and experimental results indicate that the proposed motor has advantages of a sinusoidal back-EMF waveform, a small cogging effect and a high thrust density, and it is suitable for the application of linear direct driving machine tools.
