Eight figure coils for EDS can generate not only levitation force but also propulsion and guidance forces. Besides, on-board power is gained by utilizing a harmonic magnetic field generated by these coils. It is desirable for economic efficiency that these same coils fulfill that many functions, but it is difficult to design these coils balanced for that many functions. In addition, there are various specifications to design these coils because there should be an asymmetric figure between upper and lower coils to elevate the stability between guidance and rolling, improvement of which contributes to build up the take off velocity. On the contrary, some electrical machines are designed by adopting the optimization program. This paper describes application of the optimization program for the coil specifications in EDS maglev which combines propulsion, levitation, guidance and linear generator. Using numerical examples, the specifications for optimizing each function and combined functions are examined and the relationships between the specifications and the functions are revealed.
