Linear and rotatory motors, with one degree of freedom each, are state of
the art. Actuators with both degrees of freedom exist often only as
concepts. For the linear motion, they mostly use a combination of motor and
spindle. An additional motor provides the rotating movement. Complicated
gears overlap both motions, however, high inertia and system boundaries
prohibit dynamic actuator movements. As linear motor, a solenoidmotor
enables new ways to provide a rotary-linear-actuator. Through the direct
provision of linear motion, highly dynamic positioning movements can be
realized. This work focuses on the development of such an actuator. At the
beginning, different fields of applications will be presented where a
highly dynamic rotary-linear-actuator can be used. Then, a comparison will
show that the dynamics of the solenoid motor is much higher than that of an
equivalent spindle system. The conception of the rotary-linear actuator is
based on the "Constructive Development Process". In the first step, a
function structure lists all of its sub-functions. Then the morphological
matrix assigns every sub-function multiple solutions. The guidance of the
mechanical components, and the path measurement are critical functions so
that they are considered in more detail. The results lead to five different
solution concepts, which are compared at the end of conception. After that,
it follows the constructive implementation of the preferred concept and the
analysis and optimization with regard to its deformation, modal frequency,
temperatures, assembling and costs.
