  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.
