Embodiment Construction

[0011] Further description will be made below in conjunction with the embodiments with reference to the accompanying drawings.

[0012] Such as figure 1 and figure 2 As shown, the piezoelectric motor includes a base 10, a drive module 50 arranged on the base 10, a pre-compression mechanism 30 connected between the base 10 and the drive module 50 and a contact with the drive module 50. rotor 70.

[0013] The base 10 is fixed on a fixed seat 1, and the base 10 includes a substantially square bottom plate 12, a stopper 16 is formed on the side of the bottom plate 12 close to the rotor 70, and the two sides adjacent to the bottom plate 12 and the stopper 16 are respectively A side wall 14 is formed, and both the stopper 16 and the side wall 14 extend upward perpendicular to the bottom plate 12 . Wherein the bottom plate 12 forms a flange 18 outwards on both sides where the side wall 14 is located, and a fixing groove 180 is formed on each flange 18. Fasteners such as screws pa...

Abstract

The invention discloses a piezo-electric motor, which comprises the following parts: one chassis, one movable earth on the drive module of the chassis, one prepressing device which is fixed on the chassis and one rotatable earth on the rotameter of wing base, wherein the precompaction device includes at least one elastic body which connects the device module; the device module has at least one piezo-electric slice and one shock slice which connects to the piezo-electric slice; the exoloma of shock slice contacts with rotameter; the device module has one clamp plate which connects shock slice; the contact between clamp plate and shock slice is surface contact; the block which keeps the drive modular is formed on the lateral surface of chassis. The invention improves the motor stability, which is easy to control the bottom pressure of contact point.

Description

【Technical field】 [0001] The invention relates to a motor, especially a piezoelectric motor utilizing the inverse piezoelectric effect of materials. 【Background technique】 [0002] With the continuous development of science and technology and modern industry, the application range of motors is becoming wider and wider. Although the traditional electromagnetic motor has fast speed and high power, it uses the electromagnetic force between the rotor magnet and the stator coil to drive the rotor to rotate. Not only the structure Complicated, and may cause motor failure when subjected to electromagnetic interference. For this reason, piezoelectric motors have gradually attracted widespread attention due to their small size, fast response, simple structure, and immunity to electromagnetic interference. [0003] The theory of piezoelectric motors was first proposed by scientists in the former Soviet Union. However, due to poor stability and other reasons, it was not until the rise...
