Model and analysis of integrative transverse-flux linear compressor

This paper presented a successful design of a novel integrative transverse-flux linear compressor (TFLC) which integrates compressor into a single-phase transverse-flux linear oscillating actuator (TFLOA) with moving magnet. After the construction and operational principle are introduced, the simple lumped circuit model accounting for magnetic saturation, armature reaction and axial fringing effect is proposed. Based on this model, the magnetic field in air gap is calculated, and then the optimal PM height and split ratio are found. The developed analytical model is validated by both FEM results and prototype measurements. The system resonant frequency is investigated at different load, and then the senseless control method is proposed and validated. It is shown the proposed TFLC has simple structure and can output high stability short reciprocating movement.
