  text: It has been shown previously that ``slip-slip'' operation of piezoelectric
    inertia motors allows higher velocities and smoother movements than classic ``stick-slip''
    operation. One very promising driving option is to use a superposition of multiple
    sinusoidal signals. In this contribution, previous theoretical results are validated
    experimentally. The results confirm the theoretical result that for a given maximum
    frequency, usually defined by the actuator characteristics, a signal with high
    fundamental frequency and consisting of two superposed sine waves leads to the
    highest velocity and the smoothest motion. This result is of fundamental importance
    for the further development of high-velocity piezoelectric inertia motors.

  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. These motors can operate in
    ``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
    signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
    a Coulomb friction model is sufficient in many cases, but numerical simulation
    requires microscopic time steps. This contribution proposes a much faster simulation
    technique using one evaluation per period of the excitation signal. The proposed
    technique produces results very close to those of timestep simulation for ultrasonics
    inertia motors and allows direct determination of the steady-state velocity of
    an inertia motor from the motion profile of the driving part. Thus it is a useful
    simulation technique which can be applied in both analysis and design of inertia
    motors, especially for parameter studies and optimisation.
