Description

one

The invention relates to automation and computing technology and is intended to read information from an encoder in angle-code converters.

Known are the angle-code reading elements of the transducers, containing the core rods on which the series-connected windings are located.

The purpose of the invention is to simplify the design of the device, the development of the manufacturability and assembly of the reader 1, its results.

This is achieved by the fact that the midpoints of the extreme rods of the magnetic pipe are connected to the midpoint of the central rod of the magnetic conductor, and each winding from the bottom of the connecting windings is located at the end of the corresponding magnetic rod of the magnetic conductor.

The drawing shows a schematic reading element,

The reading element contains magnetisation / c central 2 and extreme 3 n 4 cores. The midpoints of the extreme rods of the magnetic conductor are interconnected by bridges with the midpoint of the central rod of the magnetic conductor. The magistrater forms, thus, a form resembling the letter.

The rods 2, 3, 4 are placed relative to the encoder 5, which has two code tracks i and 7. At the ends of the central magnet drive rod, the primary windings 8 and 9 are connected in series according to, and at the ends of the extreme rods are two pairs of independent windings 10, 11 and 12, 13. The windings in the calde of these containers are connected in series and the counter-reading element works as follows.

When the primary windings of the intann (or a current pulse) are fed to the input, a voltage (current pulse) appears in each pair of secondary windings, the value of which is determined by the state of the magnetic system of the reading element. If, for example, pins 3 and code door are open 7, then the signals generated by windings 10 and // or 12 and 13 are equal to each other, and the secondary voltage (current pulse) is zero. When the outermost rod closes the magnetic core with a section of the encoder 5, the signal at the output of the winding // increases, and the secondary voltage (current pulse) becomes significantly different from zero. In this case, if the central rod and the unit remains in the open position, the secondary voltage (current pulse) at the output of the windings 12 and 13 is still zero.

Thus, a structurally single reading element practically performs the functions of two independently working reading elements, each of which independently interacts with its code track 6 or 7 of the encoder 5.

Subject invention

The angle-code reading element of the transducer contains magnetic cores, on the second; windings connected in series are arranged, characterized in that, in order to simplify the construction of the device, the midpoints of the extreme cores of the magnetic core are bridged to the middle point of the magnetic core, The windings are located at the end of the corresponding core of the magnetic circuit.
