Permanent magnet linear synchronous motors (PMLSMs)
have been used in a wide variety of industrial applications.
Especially, a slotless-type PMLSM is suited for precision
instruments requiring accurate position control due to low
thrust ripple. However, it has low power density because of a
large air-gap structurally [1]. Therefore, this paper proposes
optimal design of the PMLSM to obtain larger thrust and
smaller thrust ripple than already fabricated prototype
PMLSM.
Response surface methodology (RSM) is a collection of
statistical and mathematical techniques useful to find the
“best fitted” representation of the response of the physical
system under investigation. It has recently been recognized as
an effective optimization approach for design of electrical
devices when used in combination of the numerical method
for product performance simulation [2]. In RSM, a
polynomial model is generally to be constructed to represent
the relationship between the performance and the design
parameters. Thus, this model can be used to predict the
product performance as a function of design variables, and
design optimization considering multiple responses can be
carried out with much ease.
