Vapor compression refrigeration can operate electronic devices at lower temperatures even under harsh conditions， but it faces critical challenges in miniaturization and oil-free operation. This paper presents a detailed analysis and optimization of the excitation coils of the linear compressor using finite element analysis. The optimization allows the coil to be more compactly integrated with the outer stator core， further reducing the compressor's volume. A bobbinless coil was developed to increase the slot fill factor， resulting in a more compact structure. Simulation comparisons demonstrate effective enhancements in motor output capacity and efficiency. A prototype was constructed， featuring a linear motor with an outer diameter of 61 mm and a length of 36 mm. The measured electromagnetic force coefficient is 20.73 N·A-1， which is very close to the simulation result of 21.34 N·A-1. Voltage regulation experiments were also conducted under oil-free conditions， confirming that the device can maintain its performance while achieving miniaturization and oil-free operation.
