--- _id: '9784' abstract: - lang: eng 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. author: - first_name: Matthias full_name: Hunstig, Matthias last_name: Hunstig - first_name: Tobias full_name: Hemsel, Tobias last_name: Hemsel - first_name: Walter full_name: Sextro, Walter last_name: Sextro citation: ama: 'Hunstig M, Hemsel T, Sextro W.

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.' author: - first_name: Tobias full_name: Hemsel, Tobias id: '210' last_name: Hemsel - first_name: Maik full_name: Mracek, Maik last_name: Mracek - first_name: Jörg full_name: Wallaschek, Jörg last_name: Wallaschek - first_name: Piotr full_name: Vasiljev, Piotr last_name: Vasiljev citation: ama: 'Hemsel T, Mracek M, Wallaschek J, Vasiljev P.
