The design, analysis, and control of Disc-type Linear Permanent Magnet Synchronous Machines are presented in this dissertation. The machine is designed in order to have the features of high power density, high efficiency, direct drive without extra transmission device, simple mechanical structure, and wide operating speed range for the electric vehicle applications. The Feasible Triangle Technique for permanent magnet synchronous machine design is employed to increase torque density and reduce torque ripple. Magnetic theory and the finite element method are involved to establish machine mathematical model to simulate and analyze the proposed machine. The coupling field between rotor and stator can be analyzed from flux distribution by using three-dimensional finite element method. The numerical simulation and experimental results are used to verify the machine model and the operational characteristics of machine. The dissertation provides the procedures for design, analysis, and control of the proposed machine.
