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.

text: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable e.g. to drive the sunroof of a car or to lift
a car''s window, multiple miniaturized motors can be combined. But in this case
many other questions arise: the electromechanical behavior of the individual motors
differs slightly, the motor characteristics are strongly dependent on the driving
parameters and the driven load, many applications need some extra power for special
cases like overcoming higher forces periodically. Thus, the bundle of motors has
to act well organized and controlled to get an optimized drive that is not oversized
and costly.'

text: Ultrasonic linear motors have now been investigated for several years. Their
key features are high thrust forces related to their volume and good position-accuracy.
This contribution consists of two main parts. In the first part we describe the
state-of-the-art of linear piezoelectric motors. Characteristics like no-load
velocity, maximum thrust force and other technical properties of commercially
available devices will be reported as well as those of prototypes. In the second
part we report an ongoing research and development project aiming at a linear
piezoelectric motor, which is capable of surpassing some of the shortcomings of
other piezoelectric motors
