text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. It has been shown previously
in theoretical investigations that higher velocities and smoother movements can
be obtained if these steps do not contain phases of stiction (''stick-slip`` operation),
but use sliding friction only (''slip-slip`` operation). One very promising driving
option for such motors is the superposition of multiple sinusoidal signals or
harmonics. In this contribution, the theoretical results are validated experimentally.
In this context, a quick and reliable identification process for parameters describing
the friction contact is proposed. Additionally, the force generation potential
of inertia motors is investigated theoretically and experimentally. The experimental
results confirm the theoretical result that for a given maximum frequency, a signal
with a high fundamental frequency and consisting of two superposed sine waves
leads to the highest velocity and the smoothest motion, while the maximum motor
force is obtained with signals containing more harmonics. These results are of
fundamental importance for the further development of high-velocity piezoelectric
inertia motors.
