| The "Synchro" is a generic term for
a family of electromechanical devices (including
resolvers) which have
been used in angle measurement and positioning
systems for the last 50 years.
A Synchro can provide an electrical output
(at the Stator) representing
its shaft position ... or a Synchro can
provide a mechanical indication
of shaft position in response to an applied
electrical input to it's stator
winding.
Synchros can be thought of as "variable
transformers". Shaft angle
rotation, with an "AC" voltage applied to the
"Rotor" shaft winding, causes
a change in the synchro's "Stator" output
voltage.
With their rugged construction and high
reliability, Synchros have been
used since WWII as the "angle" transducer of
choice for Military, Space
and Aviation applications ... when only the
best will do.
