Description

(54) DEVICE FOR REMOTE SHIFT TRANSFER

I

The invention relates to automatic monitoring and control devices and can be used in devices for remote transfer of movements in a rectangular coordinate system.

A remote transmission device is known that contains a sensor and a receiver, each of which contains a stator, on which a winding connected to a three-phase network is located, has a rotor in the form of a circular permanent magnet suspended in a stator with three freedom systems and a frame rigidly connected to the stator, the sensor and the receiver are connected by a communication line. The disadvantage of the device is not high enough power.

A device for remote transmission of displacements is known, in which a converter is used as a sensor and a receiver.

three fixed magnetic cores that form the stator and are located relative to each other at an angle of 120, pole pieces of which are made in the form of a spherical C-shaped surface and a moving magnetic core, also made in the form of a spherical surface and attached to the lever with a hinged mount or on a cantilever cylindrical spring in the case of use as a receiver. On the fixed magnetic cores there are excitation coils connected to the three-phase network according to the star circuit, and three working coils connected in series with each other according to the open triangle 2 circuit.

A disadvantage of the known device is the low power per unit surface of the movable part, hence its large dimensions.

The purpose of the invention is to reduce the size of the device for remote transfer of movements.

The goal is achieved in those in the device for remote transfer of movements, containing a sensor and a receiver, each of which is made in the form of a stator with three-phase field windings connected to a three-phase network according to the star circuit without a neutral wire, and three working coils connected in series with each other according to the open triangle scheme, and the movable part, the sensor and the receiver are connected by a communication line, the sensor and receiver curtains are made in the form of pie-shaped magnetic cores, located dix so as to form two circles, between which is placed the movable part, designed as a smaller diameter Krasnoyarsk State University of ferromagnetic material.

The drawing shows a device for remote transfer of movements, structural diagram.

The device contains the same sensor I and receiver 2, each of which consists of a stator 3, a movable part 4, excitation windings 5 and operating winding coils 6.

The device works as follows.

When the movable part 4 of the sensor 1 deviates from the zero position for a certain distance in the plane, the mutual inductances between the excitation windings 5 and the rollers 6 change, resulting in a voltage at the output winding of the working winding, which amplitude is proportional to the deviation, and the voltage phase depends on the azimuth of the movable part 4. In turn, the voltage

the working winding of the sensor 1 creates a current in the working winding of the receiver 2, KOTopbrii, interact with the flow

excitation creates a force acting on the movable part 4 of the receiver 2 in such a way that it occupies a position similar to that of the movable part 4 of the sensor 1.

The use of the invention allows to reduce the cost of the device by reducing the size while maintaining power, or it can increase the power without increasing its size.
