folks ... i think the best way to think of it this ... a syncro and a resolver are the same things ..... one sets and sends the signal for rotational movement of the other in a system where you have 2 mechanical movents to be made... makes a proportional mechanical change via electrical input at the front end ... ie... fly by wire ... the input being the syncro side normally ..... they are also termed resolvers as well when used alone to measure rotational input.. ie.. TLR Throttle lever resolver ... it measures the angular input and sends the signal to to a FADEC or EEC or other computer for further processing and action out the other end. Now enter into the picture RVDT and LVDT's low amperage units to make Rotational or Linear inputs to control solenoids, or varying electrical input to circuit boards that actually carry or control the current ... or ... transmit positional movement to instruments and indicators and computers for monitoring. So syncro or resolver ? .... ask the engineer why he termed it that way .... they are wired the same ....
