专利汇可以提供Depolarization protection for ceramic piezoelectric motor专利检索,专利查询,专利分析的服务。并且A piezoelectric motor employs a bending strip or several bending strips having piezoelectric ceramic elements which are mechanically connected in parallel in a single or several packages wherein each bending strip undergoes bending or torsional deformation upon the application of an alternating electrical voltage applied to one or several electrode pairs carried by the ceramic bending strip. The direction of the voltage reverses from between the same direction and the direction opposite to that of the permanent polarization of the ceramic material between the pair of electrodes and the motor includes a circuit comprising parallel connected rectifier and resistor elements connected in series with pairs of electrodes and having the rectifier poled with its forward direction opposite to that of the permanent polarization of the ceramic material and the resistor is dimensioned such that the peak voltage across a pair of electrodes does not exceed a predetermined fraction of the peak value of the applied alternating voltage during the non-conducting phase of the rectifier.,下面是Depolarization protection for ceramic piezoelectric motor专利的具体信息内容。
