Abstract: This paper is presented for suggesting the analytic methodology,
Space Harmonic Method, for slotless Permanent Magnet Linear Synchronous
Motor(PMLSM) implying the real physical aspect of structure. Especially, the
details of the end-effect, a kind of fringing effect resulted from the moving
magnet, can be investigated effectively by adopting the proposed method.
Furthermore, a distinctive feature of EMF distribution closely concerned with
end-effect will be overviewed theoretically.
Keywords: space harmonic method, Permanent Magnet Linear Synchronous Motor(PMLSM), end-effect
