In this paper, a novel Multi-loop Moving Coil Large Output Volume Linear Compressors (M-MC-L-LC, Max 381.3cc) is proposed. A Co-core Bilateral Reverse Coil(CBRC) and a new Halbach permanent magnet ring array structure are proposed for the first time and applied to the development of prototype. The M-MC-L-LC electromagnetic force calculation equation is derived, the moving offset characteristics under different pressure ratios are studied, and a mathematical model that can reflect the moving offset law is established. Introduction the DC offset control method to solve the moving offset problem. Development the M-MC-L-LC prototype and construction a dynamic test rig for compressors. Experimental results show that increasing DC voltage countervails the moving offset and significantly increases the discharge pressure. The theoretical error of moving offset is within 8% and the mechanical efficiency of prototype is approximately 11.4% higher than that of the conventional compressor. The results of study have theoretical and practical implications for other linear compression moving offset analysis and accurate regulation of refrigeration capacity.
