N2 - In this work, a design method for a linear-rotary
electromagnetic actuator (LREA) presented recently in [1] is
developed. The design method is based on an analytical model
of magnetic flux. An assumption of optimal flux densities in the
magnetic circuit of the actuator allows calculation of the required
magnetomotive force and some related dimensions, however, most
geometrical parameters must be chosen manually. The influence
of each particular parameter of the actuator on the torque and
inductance characteristics is analyzed to find advantageous parameter
values. This analysis is performed for dimension ratios,
which makes it universal for various sizes of the actuator. Further,
we present the influence of some parameter combinations on
the torque density. Finally, the analytical flux model is applied
for stochastic optimization of the design. This procedure allows
creation of much more efficient designs comparing to manual
choosing of parameters and becomes feasible only with the
analytical flux model proposed earlier, since calculation of threedimensional
magnetic field using finite element analysis (FEA)
would require huge computational capabilities in this case.
