Accurate dynamic models of electromechanical
devices are essential in order to develop effective motion
control strategies of such devices. The effects of fringing
flux can not be ignored when dealing with electromagnetic
devices that present air gaps. So far parametric models
applied to compute the motion of electromechanical
devices do not include accurate formulations to take into
account this effect.
This paper develops an experimental method to obtain a
simple analytic formulation of such an effect that can be
used to calculate the linear motion of the aforesaid devices
in a proper and accurate way. These effects are introduced
in a robust and low time-consuming parametric model and
the results are shown. Measured data has been compared
with data obtained from simulations thus validating the
simplicity and effectiveness of the proposed methodology.
