A single-phase tubular permanent-magnet linear machine (PMLM) with hybrid Halbach/axially-magnetized PM arrays is proposed for free-piston Stirling power generation system. Machine topology and operating principle are elaborately illustrated. With the sinusoidal speed characteristic of the free-piston Stirling engine considered. the proposed machine is designed and calculated by finit... https://www.parisnaturalfoodes.shop/product-category/coconut-butter-org/
