Abstract The research is devoted to the peculiarities of construction of “angle-parameter-code” transducers. It is shown that the traditional structure to form only a digital equivalent of movement from the output signals of the angle-component solver is rather simple. Modern foreign “Resolver-to-Digital Converters” (RDC) form, unlike the single-channel analogue, a digital equivalent of speed. This simplifies an electromechanical component of mechatronic systems (MS) by eliminating the tachometer connected with the working mechanism and the actuating motor through a mechanical transmission or directly. In the latter case, the traditional use of the tachometer at low revolutions occurs due to fundamental difficulties of receiving reliable information about the traverse speed. This limits scopes of application of a progressive gearless electric drive. Presented developments are beholden for their continuous improvement to numerous applications of the angle-component solver. Their durability is defined by remarkable properties which are not surpassed by modern angle-data transmitters based on other physical principles. Before the advent of digital systems synchro and angle-component solver were the most accurate and reliable analog primary transducers of the angular location. Mechatronic systems created on the basis of these transducers meet the highest standards and are able to operate successfully in a wide range of environmental factors – temperature, humidity, vibration and strokes. Due to the advent of digital systems aroused attempts of the creation of converters with a digital output, in which a basic primary transducer maintained. The development of this area proved to be extremely successful – currently established foreign and domestic RDC compete with code converters in a resolving capacity, accuracy and dynamic indicators. On a set of required characteristics no type of angle converters can compete with them in certain cases.
