FEM-Aided Analytical Model and Control of SSLFSM Thrust Force

Nowadays, linear machines have more developed for high power applications such as long-distance transportation. But, their expensive investment and some technical problems are major challenges of these technologies. Here, a linear flux switching machine (LFSM) with segmented secondary is studied. These fluctuations, in other words, detent force have a negative impact on machine performance. The effect of these issues can be notably reduced with a suitable design. In this paper, a FEM-based Analytical model is presented for a linear flux switching machine. The results of analytical model are verified by FEM Simulations and then a control method is proposed to reduce fluctuations of the thrust force.
