A tubular hybrid Halbach/axially-magnetized permanent-magnet linear machine
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 mercury metallic lexus Stirling engine considered
