A resolver is a three phase rotating transformer. One stator is fed a
10kz AC waveform. The resolver is attached to the servomotor via a
reduction gear. When the output of the resolver is sent to the
resolver processor (extremely simplified explanation) its waveform is
compared to a clock and converted to a digital serial out then
multiplexed to a parallel out and sent to the servo CPU.
Here is a block diagram of the basic operation
http://www.freepatentsonline.com/7057399-0-large.jpg
Position and speed is the responsibility of the resolver. Motor load
is probably determined via the tach generator, a single phase
generator bolted on the end of the servomotor rotor housing.
BTW this machine is a Bayer Acroloc ES chucker with
Yasnac/Yaskawa/Singer-Kearfott/Bayer/Getty's guts circa 1982.
