High resolution optical encoders are used in industrial servo drives with position and/or speed control for providing the respective feedback signals. In applications with lower accuracy requirements resolvers are used as feedback sensors with respect to lower cost. As a resolver is nothing else than an electrical AC machine of special design, there is the basic idea to operate the servo motor itself like a resolver - in parallel to its original drive operation, of course. High frequency… CONTINUE READING
