ABSTRACT: In this paper proposes a Finite
Element Methods analyzing applied to the linear tubular stepping actuator. The
linear displacement is modeled by means of a layer of finite elements placed in
the air gap. The design of the linear stepper motor for achieving a specific
performance requires the choice of appropriate tooth geometry. The magnetic field
of the actuator has been analyzed using the finite element method over a
current-displacement variation. The magneto static field and electromagnetic
force was introduced in order to predict before construction, the inductance
values according to the displacement and the currents into the coils. The
results were obtained for the magnetic flux density distribution and the
electromagnetic force for different positions and current.
