Abstract

This paper is devoted to the research of linear permanent magnet synchronous motor (PMSM) intended to drive low-speed long-stroke single-stage piston compressor. Linear PMSM design was developed. Its magnetic field was simulated to obtain the PMSM starting characteristic. The optimization task of the highest power efficiency was solved in this work. The experimental PMSM sample was manufactured and researched. The simulated and experimental forces amounts have a significant difference. Probably it is caused by the scattering fluxes. Thus, it is recommended to design the winding divided into coils. In this case, some coils can be switched off during the PMSM operation. It reduces scattering fluxes and increases power efficiency. Besides, the research results showed that the magnets’ form and magnetization significantly affect PMSM power efficiency. The most important result of this study is understanding the possibility of PMSM usage for piston compressors driving.
