单模态并减摩驱动的单驱动足板形压电电机制造技术

一种单模态并减摩驱动的单驱动足板形压电电机，属于压电电机类。该电机由板形定子和一直线导轨组成。所述导轨由预压力压在板形定子的驱动足上。所述定子整体呈板形，包括振子主体和单驱动足两部分；其中由压电陶瓷材料构成的振子主体呈长方体，其上有三个极化分区；由耐磨材料构成的单驱动足通过粘接或焊接或烧结与振子主体结合为一体。该电机设计有共振和非共振两种工作模式。在共振工作模式，定子在斜直线运动轨迹的单模态并减摩驱动下工作，推动导轨正反向运动；在非共振工作模式，定子在强迫振动并减摩驱动下工作，推动导轨正反向运动。相对于现有压电电机，该压电电机不但能够有效地提高输出功率，而且驱动频带宽、工作可靠。（*该技术在2023年保护过期，可自由使用*）

Single mode and antifriction driven single drive footplate shaped piezoelectric motor

A single modal and antifriction driven single drive footplate shaped piezoelectric motor, which belongs to the class of piezoelectric motor. The motor is composed of a plate stator and a linear guide rail. The guide rail is pressed by the pre pressure on the driving foot of the plate shaped stator. The stator is in the form of a plate, which comprises a vibrator body and single driving foot is composed of two parts; the piezoelectric ceramic vibrator main body is cuboid and three polarization partition it; the single driving foot by adhesion or welding or sintering and oscillator subject combination composed of wear resistant materials. The motor is designed with two modes of resonance and non resonance. In the resonant mode, single mode stator in oblique line trajectory and friction drive to work, push forward and reverse movement guide; in the non resonant mode, the stator in the forced vibration and friction drive to work, push forward and reverse movement guide. Compared with the existing piezoelectric motor, the piezoelectric motor not only can effectively improve the output power, but also has a wide drive frequency and reliable operation.
