摘要： In a driving and control apparatus of a piezoelectric ultrasonic motor, a controller controls a selection of a first channel or a second channel of the piezoelectric ultrasonic motor as a driving channel. A switch part selects one of the first and second channels as the driving channel and the other as a detection channel, and supplies the driving voltage to the piezoelectric ultrasonic motor through the selected driving channel. A phase detector detects a voltage outputted from the piezoelectric ultrasonic motor through the detection channel, calculates a phase deviation, and outputs a phase difference voltage corresponding to the phase deviation. A voltage controlled oscillator generates the oscillation voltage and controls a phase of the oscillation voltage according to the phase difference voltage. A frequency divider divides the oscillation voltage by two to generate the driving voltage, and supplies the divided oscillation voltage to the piezoelectric ultrasonic motor through the driving channel.

摘要： An improved motor employs a stator which includes a piezoelectric wafer that is poled across its thickness dimension so that a signal applied thereacross results in either an inward or outward movement of the periphery of the wafer. A pair of end caps are placed on opposed surfaces of the wafer and are adhered thereto at their respective peripheries. Each end cap includes a centrally located driving segment, a series of peripheral segments adhered to periphery of the wafer and a plurality of arms connecting the peripheral segments to the driving segment. A rotor includes a driven portion which mates with the driving segment and is driven thereby. Application of a signal across the thickness of the piezoelectric wafer results in rotary motion being imparted to the driving segment via flexure of the arms (as a result of movement of the peripheral segments of the end caps). Further embodiments provide both rotary and linear motions.
