The structure of field system which gives a high flux density in air-gap is proposed for a linear synchronous motor (LSM) with large gap. The flux density and force density of LSM are analyzed respectively by using two-dimensional finite element method. The air-gap flux density exceeds the value of remanent magnetic flux density of used permanent magnet (PM). The thrust density of 100kN/m2 can be obtained easily. This structure can be also applied to a rotational machine and etc.
