Abstract: 
The
goal is to present a more accurate model for optimization of design and of a
supply control. The object is an electromagnetic linear actuator
which is built of series of coils and of a ferromagnetic moving core.
The coils are supplied by time series of current impulses. Even though that linear electromagnetic actuators are commonly known
their applications are not wide. This is mainly because of the low energy
efficiency. The efficiency is here understood as a ratio of the kinetic energy
of the core at the outlet of the device to the electric supply energy
delivered to the coil. The efficiency can be improved by design parameters
optimization and by the accurate supply control, as well, but an adequate
accuracy of the mathematical model is required for optimization process. In
this paper a simulation model is presented, with
a careful consideration of the hysteresis of ferromagnetic parts, of
nonlinear distribution of the magnetic field and of the dimensions of all
coils. The timedependent non uniformly distributed magnetic field is
analyzed by the FEM method. The computer simulation results and experimental
data of magnetic flux density are compared. Special sensors of the Colossal
Magneto Resistance (CMR) effect have been used for verification of the
simulation results (Balevicius et al. 2005,
Schneider et al. 2007). The MultiAttribute optimization has been completed
and the Pareto set is defined, by evolutionary optimization methods.
