  abstract = {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.},
