Electrical Resolver

Model / MPN: ESH-8-F-31A13 | NSN: 5990-01-084-0807
ITAR Registered seal

An item consisting of a rotor and a stator inductively coupled. It usually has two rotor windings displaced from each other by 90 degrees and two stator windings similarly displaced. The output voltag (s) is a trigonometric function of the input voltage(s) and the angular displacement of the rotor with respect to the stator. See also synchro (as modified) and goniometer, electrical. Excludes transolver, electrical and potentiometer sine/cosine electrical resolvers.
