  • Abstract
    A quarternary system ceramic with high piezoelectric constants, particularly a high d31 and high d33, was studied. The composition of the materials is PMN-PNN-PZT doped with oxides of Sr, Bi, Sn and La etc. The properties of the materials are as follow: d33=(600-750)10-12C/N, d31=(-300-398)×10-12C/N, Kp=0.68-0.75. By using this material, a new type of rotational stepper motor, a piezoelectric electro-rheological motor had been made. This kind of motor has unique advantages: no vibration noise, zero wear, low consumed power, large travel range and high resolution etc
