초록

This paper presents a design and analysis solutions for the general class of iron-cored permanent magnet linear synchronous motor with Halbach (PMLSM). In our design and analysis, rotor consisting of permanent magnets rotor and slot less iron-cored coil stator are treated in a uniform way via vector potential. For one such motor structure, we give analytical formulas for its magnetic field, back electromotive force, inductance of winding coil, and trust force. We also provide performance comparisons of three types according to iron-cored and PM array.
