6. Research Prototype and Experiments

In this chapter, the experimental investigation is conducted on the research prototype of the tubular linear machine with dual Halbach array to verify the analytical magnetic field model, force output model, and armature reaction field model proposed in Chaps. 2, 3, and 4, respectively. The experimental results also facilitate the visualization of the magnetic field distribution, the force output variation, and armature reaction field analysis of the linear machine. As shown in Fig. 6.1, the experimental investigation of the tubular linear machine consists of three major tasks: measurement of the magnetic field distribution, the force output variation, and the armature reaction change. This chapter begins with description of research prototype, magnetic field measurement procedure of the tubular linear machine, and the corresponding data processing and analysis. The force and the armature reaction measurements are carried out on the machine and compared with the theoretical models. The experimental results confirm the proposed analytical model for further control study of the linear machine.
