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

Изобретение относитс  к электрическим двигател м, а именно к малогабаритным пьезодвигател м.FIELD OF THE INVENTION The invention relates to electric motors, namely, small-sized piezoelectric motors.

Цель изобретени  - повышение КПД двигател .The purpose of the invention is to increase the efficiency of the engine.

На фиг. 1 изображен двигатель с пьезоэлектрическим статором, продольный разрез; на фиг. 2 - то же, поперечный разрез; на фиг. 3 - пьезоэлектрический двигатель с пьезоэлектрическим ротором.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.

Пьезоэлектрический двигатель (фиг. 1 и 2) HMeej корпус 1, внутри которого размещен статор 2 - полый цилиндрический элемент из пьезоактивного материала с радиальной пол ризацией. Между корпусом 1 и статором 2 размещены резиновые проклад- ки 3. На внутренней поверхности цилиндрического элемента - статора 2 нанесен износоустойчивый слой 4, например из хрома , акустически св занный со статором 2, этот же слой 4 вместе со слоем металлизации наружной поверхности (не показан) образует электроды пьезоэлемента, присоединенные к токоподводам 5. Внутри статора 2 и соосно с ним помещен ротор 6 - цилиндрический элемент с консольно закрепленными в его теле упругими металлическими пластинами 7, свободные концы которых выполн ют функции толкателей. Пластины 7 установлены к поверхност м статора 2 под углом, отличным от 90°. Направление вектора пол ризации обозначено буквой Р.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.

В варианте двигател  (фиг. 3) из пьезоактивного материала выполнен ротор 8. В статоре 9 консольно закреплены металлические пластины 7, также выполн ющие функции толкателей.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.

Пьезоэлектрический двигатель работает следующим образом.The piezoelectric motor works as follows.

При подаче на элемент - статор 2 (фиг. 1) или ротор 8 (фиг. 3), выполненныйWhen applied to the element - the stator 2 (Fig. 1) or the rotor 8 (Fig. 3), made

из пьезоактивного матерала, электрического напр жени  определенной частоты в нем возникают радиальные колебани .From the piezoactive material, electrical voltage of a certain frequency, radial oscillations arise in it.

При сжатии цилиндрического элемента за счет сил трени  и упругости пластин 7 ротор повернетс  на некоторый угол. При расширении цилиндра либо поверхность статора отрываетс  от концов пластины, либо силы трени  в контакте уменьшаютс  настолько, что происходит проскальзывание ротора относительно статора. Такой процесс повтор етс  с частотой возбуждающего напр жени  (дес тки кГц) и сопровождаетс  возникновением посто нного момента, привод щего двигатель во вращение.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.
