A pair of selsins only transfer positional shaft analog information and a moderate amount of torque often used for indicators. a single winding on the rotor connected by slip rings to a source of AC power and an identical AC source (usually the same one ) is connected to the second unit. Three stator windings produce voltage proportional induced according to the rotor location and are connected to the equivalent stator windings in the second unit. Because the magnetic fields interact to position the two rotors in the same relative positions. Also angle correcting transformers are made which have a rotor with three windings and when the stator of one unit is wired to the rotor of the angle correcting transformer and the stator of the second selsin is wired to the stator of the error correcting unit it produces a resolver function. I allways thought it interesting that all voltages on all windings although different in amplitude are exactly the same phase.
