【Abstract】 Since the motor used for the linear compressor suffers such problems as stability and reliability, in this article a moving-coil linear motor is designed based on the Halbach permanent-magnet array form; the effects of the permanent-magnet array arrangement, air-gap thickness, inner-and-outer magnetic yoke and coil dimensions on the motor performance are solved with the help of the finite-element analysis. With the motor performance, assembly process and other factors taken into consideration, the structure and dimensions of the linear motor’s each key component are optimized, so as to improve the inner-and-outer magnetic yoke’s space utilization, enhance the magnetic circuit’s stability and eliminate the location of the concentrated electromagnetic induction intensity. Finally, the optimized motor’s performance is simulated and verified through a series of experiment.更多还原
