The universal of resolver
Thinks to resolver used brushless, no - contact metal components, so it making the overall stability, reliability and anti-interference of resolver have more advantage than optical encoder, at the same time, the characters of low cost and long life span of resolver made it was widely used in various sectors. Resolver’ applications develop rapidly in recent. In addition to the traditional, requiring high reliability military, aerospace outside the field, in the industrial, transportation, and civilian areas has also been widely used.
Over the years, with the improvement of industrial automation level, with the increasingly high demand for energy saving. The application of high efficiency, energy saving significant application of permanent magnet AC motors is more extensive. The permanent magnet dc motor position sensor original mostly is optical encoder, but all these years, it quickly was replaced by rotary transformer.
