Description

I

This invention relates to the field of computing.

A known converter comprising a fixed hollow cylindrical magnetic core with interconnected excitation windings, inside of which a movable magnetic core arranged in the viel of a hollow cylinder and a fixed solid magnetic core with measuring windings interconnected through a movable magnetic core are coaxially arranged with it.

However, this converter can only reproduce linear functions.

The proposed functional converter is characterized in that in it the movable magnetic core is made with a shaped opening and moving along the axis of rotation.

This makes it possible to reproduce various non-linear functions.

The scheme of the proposed. Converter is shown in the drawing.

The functional converter consists of a fixed hollow cylindrical magnetic core / with excitation windings 2, measuring windings 3 of a conductive Spring, a fixed flat magnetic core 4 and a movable magnetic core 5. The sections of the excitation winding are connected in series and opposite, and the measuring one is sequentially and in alignment through the hole

movable magnetic circuit. During its rotation, the movable magnet moves evenly along the axis (for example, along the thread), and the gap between the movable and stationary magnetic cores changes according to the laws corresponding to the required function.

When an alternating current flows through the field winding with the number of turns W, a working magnetic flux is created, which, crossing the turns of the winding measuring winding, induces an emf in them.

where WH.Q is the number of simultaneously winding turns of the measuring winding;

F is the value of the flow created by the excitation winding and crossing the measuring winding:

Here g is the specific magnetic conductor in the flow path, which comes from per unit of angle of rotation and is a function of the angle of rotation:

Taking into account both expressions, we obtain (a), the form of this function is determined by the profile of the hole.
