A stick-slip piezo motor. At least one voltage source is connected to a piezo motor. The piezo motor has at least one oscillating piezo element and at least one moving friction element connected to the oscillating piezo element. The moving friction element moves in a desired travel direction. A computer is programmed to control the voltage source to deliver voltage to the piezo motor at a predetermined frequency and amplitude to control the speed of the piezo motor. The computer is programmed to hold the frequency constant while varying the amplitude to adjust the speed of the piezo motor. In a preferred embodiment the computer is programmed to hold the frequency constant at an ultrasonic frequency. In another preferred embodiment the computer is programmed to hold the frequency constant at a value of 15 kHz or higher.

The disclosure relates to a drive means for non-resonant linear and/or rotary positioning of an object, comprising at least two piezoelectric or electrostrictive actuator groups, where-in a first actuator group moves a first runner portion relative to a stationary base of the drive means according to the principle of an inertia drive, and by means of the second actuator group a second runner portion is moved relative to the first runner portion with a limited range of movement in the high-resolution scan mode, wherein a common electrical control signal is applied to the first and second actuator groups.
