Electromechanical systems and mechatronics are paramount in industrial applications.
Electromagnetic actuators represent a key component in these systems. Translational and
rotational actuators usually operate at DC or sub 100 Hz AC frequencies, with air gaps limited to
the order of millimeters to ensure efficient operation. Conversely, efficient wireless transfer of
electrical power has become possible over air gaps of several centimeters by resonating
magnetically coupled transmitter and receiver coils. Force interactions between resonator coils
can be employed for actuation in the resonant wireless power transfer (RWPT) frequency range
(>30kHz), such that resonant wireless power transfer and actuation can be combined for remote
and embedded actuators. The magnetic fields in resonator systems can be magnified and
reshaped by magnetic materials to improve magnetic coupling. Specifically, ferrites can be used in
the RWPT frequency range and allow high power density magnetic interactions with limited heat
dissipation in the material. The proposed research aims to study force interactions between
resonators by using analytical and finite element models. Three demonstrator cases will be
designed, supported by simulations. These exemplary setups with low numbers of resonators will
be optimized to maximize their specific mechanical power output.
