Description

one

The invention relates to the field of electrical engineering, in particular, to electric motors, using electromechanical transducers having piezoelectric characteristics for converting electrical energy into mechanical energy, and can be used, for example, to make small-sized ELECTRIC MOTORS.

A vibromotor is known, containing a generator, a rotor and a piezoelectric transducer, which is made of plates, the image of the X triangle, which interacts with the rotor to its vertices, and the electrodes of each plate are connected to a three-phase generator 1.

The disadvantages of this vibrator are that it has low rotational moment and insufficient uniformity of rotor speed, in addition, piezoelectric non-transformers are fixed with one meter and fasteners undergo efforts that reduce the reliability of this engine. At the same time, the vibro-vibrator has a relatively large size due to its complex structure.

A piezoelectric motor, a voltage-containing generator, a piezoelectric element in a ring and a rotor 2 are known.

The disadvantages of the well-known engine are: 1 they have large dimensions, a low twist, a rotor torque and unevenness of its lying.

The purpose of the invention is to reduce the gaba (itov engine, novilenii rotor torque and its uniform rotation.

This goal is achieved by the fact that said piezoceramic element is made with a cone-shaped inner surface and plates elastically pressed against it, rotated at an angle to the axis of the rotor and rigidly fixed on the rotor, are pressed to it.
