Basic resolvers are two-pole resolvers, meaning that the angular information is the mechanical angle of the stator. These devices can deliver the absolute angle position. Other types of resolver are multipole resolvers. They have 2"p" poles ("p" pole pairs), and thus can deliver "p" cycles in one rotation of the rotor: the electrical angle is "p" times the mechanical angle. Some types of resolvers include both types, with the 2-pole windings used for absolute position and the multipole windings for accurate position. Two-pole resolvers can usually reach angular accuracy up to about ±5′, whereas a multipole resolver can provide better accuracy, up to 10′′ for 16-pole resolvers, to even 1′′ for 128-pole resolvers.
