Description

one

The invention relates to electric micromachines and can be used in automation devices and computer technology.

The purpose of the invention is to improve accuracy by reducing the conversion error of a rotating transformer.

The drawing shows an example of the distribution of the windings on the stator magnet cable.

The proposed transformer contains excitation winding 1, the first phase of the output winding 2, the second phase of the output winding 3, additional windings 4 and 5, sections 6 and 7 of the additional windings.

The invention is illustrated by the example of execution in the form of induction reductosin with its electrical reduction factor and the number of teeth of the stator E 12. The excitation winding 1 is of a tooth-pole type, and the output windings 2 and 3 are distributed according to the laws

W is constructively constant. To compensate for the constant component of the EMF, additional windings 4 and 5 are connected in series to the output windings. Each of the additional windings consists of: two groups of sections 6 and 7, repeating the law of distribution of the excitation winding, having the same number of rtn turns and located on the H-Editor; .

The conductor is diametrically opposed. When the excitation winding is connected to the power source and the presence of misalignment (bo or eccentricity) of the magnetic conductors in the sections of the additional winding is induced by the EMF changing according to the law

and in sections - by law

where K is the proportionality coefficient;

& is the misalignment magnet of the wires;

Uu - the value of the nominal air gap; about - the angle of rotation of the rotor.

The inclusion of sections 6 and 7 consistently leads to the disappearance of the EMF component from the unevenness of the gap. At the same time, since windings 4 and 5 are laid according to a law similar to an excitation winding, a EMF component remains in them that does not change from the angle of rotation and compensates (with the appropriate polarity of connection) the output windings.

The invention does not exclude the possibility of compensating for other components of the fault, for example, from nonperpendicular phase. To do this, it is enough to connect other additional windings in series with the output.

Thus, compensation is provided for errors in the presence of an uneven air gap, which generally reduces the error of conversion.
