Abstract

The electric motor system incorporates a stator (2) and a rotor (3), in addition to a vibrator (7) operated by a piezo-electric device. The stator is in the form of a flat plate (10) mounted on a knife edge pivot (9) with electrodes (12) fitted on either side of the plate on the side remote from the rotor. The edge of the plate near the rotor carries a magnetic strip (18) which is energised intermittently to actuate the rotor (3) which is in the form of a hollow cylinder mounted on a concentric spindle (15) with end bearings (4) more elaborate devices use several strips or pairs of rotors revolving in opposite directions.

Description

FIELD OF THE INVENTION The invention relates to electric motors, namely, small-sized piezoelectric motors.
The purpose of the invention is to increase the efficiency of the engine.
FIG. 1 shows a motor with a piezoelectric stator, longitudinal section; in fig. 2 - the same, cross section; in fig. 3 - piezoelectric engine with a piezoelectric rotor.
Piezoelectric motor (Fig. 1 and 2) HMeej body 1, inside of which is located the stator 2 - a hollow cylindrical element of piezoactive material with radial polarization. Rubber pads 3 are placed between the housing 1 and the stator 2. On the inner surface of the cylindrical element - the stator 2, a wear-resistant layer 4, for example chromium, acoustically coupled to the stator 2, is applied, the same layer 4 together with the outer surface metallization layer (not shown ) forms the electrodes of the piezoelectric element connected to the current leads 5. Inside the stator 2 and coaxially with it is placed the rotor 6 - a cylindrical element with elastic metal plates 7 cantileverly fixed in its body, the free ends of which are made nktsii pushers. The plates 7 are mounted to the surfaces of the stator 2 at an angle other than 90 °. The direction of the polarization vector is denoted by the letter P.
In the engine variant (Fig. 3), a rotor 8 is made of a piezo-active material. In the stator 9, metal plates 7, which also function as pushers, are cantilevered.
The piezoelectric motor works as follows.
When applied to the element - the stator 2 (Fig. 1) or the rotor 8 (Fig. 3), made
From the piezoactive material, electrical voltage of a certain frequency, radial oscillations arise in it.
When the cylindrical element is compressed due to the friction forces and the elasticity of the plates 7, the rotor will turn through a certain angle. When the cylinder expands, either the surface of the stator is detached from the plate ends, or the frictional forces at the contact decrease so much that the rotor slips relative to the stator. Such a process repeats at an excitation voltage frequency (tens of kHz) and is accompanied by the occurrence of a constant torque driving the motor.
