摘要： A stator includes a longitudinal-vibration sensing electrode. The stator also includes a torsional-vibration sensing piezoelectric element and a torsional-vibration sensing electrode plate for sensing torsional vibrations. A voltage signal from the torsional-vibration sensing electrode plate or a voltage signal from the longitudinal-vibration sensing electrode is sensed. Then, a drive voltage signal for driving the stator is generated in a self-excited oscillation drive circuit in such a manner that an actual vibrational frequency of the stator substantially coincides with a resonance frequency. Thereafter, the generated drive voltage signal is applied between a drive electrode and each one of first and second electrode plates.

摘要： An ultrasonic motor having a stator in which at least a longitudinal vibration is generated and a rotor rotatably mounted on the stator. Slanted slits are formed on the cylindrical surface of the rotor, which convert a part of the longitudinal vibration in the stator into a twisting vibration that gives the rotor a rotational force. The slits are slanted to the rotational direction of the rotor. The rotor is rotated at a higher speed because of the slits. The form of the slits may be selectively varied according to desired characteristics of the ultrasonic motor.

摘要： A lower metal block of a stator includes a plurality of securing projections, which engage with an external member and are arranged in an outer peripheral surface of the lower metal block at generally equal angular intervals. Each securing projection is circumferentially located between corresponding two of slits of the lower metal block and has first and second axial ends, which are opposed to one another in a direction generally parallel to the axial direction of the stator and are oriented toward first and second axial ends, respectively, of the stator. The first axial end of each securing projection is axially positioned within an axial extent of the slits, which is measured in the axial direction of the stator.

摘要： A control apparatus controls an ultrasonic motor. The ultrasonic motor includes a stator, a piezoelectric element provided in the stator, and a rotor. The rotor is slidably pressed against the stator. When a driving high frequency voltage is applied to the piezoelectric element, the stator is vibrated to rotate the rotor. The control apparatus includes measuring means. The measuring means changes the frequency of a searching high frequency voltage, the searching high frequency voltage being lower than the driving high frequency voltage, thereby measuring a resonance frequency of the ultrasonic motor. The control apparatus drives the motor in a favorable manner.
