Abstract: A starting-process controller for starting a piezomotor, having a voltage-controlled oscillator, a power output stage, and a resonant converter. The oscillator generates the control signals required for the power output stage and the resonance converter converts the stepped output voltage from the power output stage into a sinusoidal voltage at the output. The resonance converter drives the piezomotor with the voltage. The motor current that flows when the piezomotor is driven is measured and compared with the phase of the drive voltage in a phase comparator. The comparison output signal is a measure of the phase difference at the time between current and voltage. A phase-locked loop filter smoothes the phase-difference signal for controling the oscillator. The controller includes a start-assisting circuit element that fixes the output voltage from the phase-locked loop filter at start-up and thus applies a constant voltage to the input of the voltage-controlled oscillator.

Abstract: The actuator has an elongated piezoelectric resonator (3) for performing longitudinal vibrations acted on by elastic arrangement (10) mainly supported in the resonator's longitudinal direction and exerting a force on it in the direction of the movable part. The resonant frequency of the elastic arrangement is much lower than that of the resonator, which is guided perpendicularly to its length by at least one guide element (4,5). Independent claims are also included for the following: an electrically powered razor.

Abstract: The invention relates to a starting-process controller for starting a piezomotor (4), having a voltage-controlled oscillator (1)(VCO), a power output stage (2), and a resonant converter (3), wherein the oscillator (VCO) generates the control signals required for the power output stage (2), and the resonance converter (3) converts the stepped output voltage from the power output stage (2) into a sinusoidal voltage at the output of the resonance converter (3), with which voltage the resonance converter (3) drives the piezomotor (4). The motor current that flows when the piezomotor (4) is driven is measured and compared with the phase of the drive voltage in a phase comparator (6). The output signal from the phase comparator (6) then is a measure for the phase difference at the time between current and voltage. A phase-locked loop filter (8) smoothes the phase-difference signal, which in turn controls the oscillator (1)(VCO). This starting-process controller (11) comprises a start-assisting circuit element (10) that fixes the output voltage from the phase-locked loop filter (8) at start-up and thus applies a constant voltage to the input of the voltage-controlled oscillator (1)(VCO).

Abstract: The motor has a square piezoelement (1). The motor has an arrangement for causing oscillating of the piezoelement in an oxy plane. On a surface (10) of the piezoelement perpendicular to its impact direction is a piston (2) for transmitting a force in the impact direction and a biasing element (3), opposite this surface, for applying a bias force. The piezoelement (1) is held, by a tensioning element without any bias in the direction perpendicular to the impact direction.
