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.

摘要： A piezoelectric transformer using a piezoelectric annulus, divided into sections, includes at least one input and one output electrode configuration. The input electrodes are formed by covering top and bottom surfaces of the divided section of piezoelectric annulus. The low impedance portions, which are input regions, are poled parallel to the thickness direction and the high impedance portions, which are output regions, are poled tangentially. The transformer is operable at several radial mode resonance frequencies of piezoelectric ring. Two stepped up ac output voltages, in phase or 180 degree out of phase, can be obtained at several resonance frequencies of the piezoelectric annulus. The transformer is also operable as a step-down transformer by inverting the input and output ports.

摘要： A piezoelectric ultrasonic motor having 2-dimensional positioning movement includes a stator. The stator includes a piezoelectric ceramic bar and an electrode disposed on the bar. Each bar includes two wings that are separated by a predetermined angle to form a predetermined shape. A power source is used to apply a voltage to the stator to excite a bending mode vibration in the each of the wings, and the combined motion of the two wings produces an elliptical motion at a tip of the wing. A load is operatively connected to the stator, such that a portion of the load in contact with the stator is driven to move linearly through a frictional force between the load and the stator, due to the elliptical motion at the tip of the wing.

The motor includes a stator having a piezoelectric ceramic disc polarized in the radial direction and bounded by a top electrode and a segmented bottom electrode. The motor also includes a power source for applying two pairs of alternating voltages to the bottom electrode segments to excite a shear-shear mode vibration in the stator, resulting in a shear-shear mode flexure traveling wave in the stator. The motor further includes a rotor operatively connected to the stator, and the stator is driven to rotate through a frictional force between the rotor and the stator due to the traveling wave deformation of the stator. A linear ultrasonic piezoelectric motor and method of exciting a flexure traveling wave to linearly drive the motor is provided. The motor includes a stator having a rectangular piezoelectric ceramic plate that is polarized in the longitudinal direction. The motor also includes a power source for applying two pairs of alternating voltages to the bottom electrode segments to excite a shear-shear mode vibration in the stator, resulting in a shear-shear mode flexure traveling wave in the stator. The motor further includes a slider operatively connected to the stator, and the stator is driven to move linearly through a frictional force between the slider and the stator due to the traveling wave deformation of the stator.
