Position Transducers/Sensors
The resolver is a highly accurate and highly dependable device
for absolute position shaft encoding. Resolvers have a reliable
track record of applications in aerospace, military, and indus-
try, where they have been used for decades for position sens-
ing. Some of the common applications are radar antenna posi-
tion sensing, missile guidance systems, NC machine position
feedback, automotive stamping presses, 2-piece-can manufac-
turing presses and packaging machines. The resolver is
designed to operate reliably under extremely hostile environ-
ments such as continuous mechanical shock, vibration,
extreme temperature and humidity changes, oil mist, coolants,
and solvents. The resolver is a passive transducer. It is a brush-
less rotary transformer with one rotor and two stator windings.
The stator windings are electrically 90° out-of-phase with each
other. As the shaft rotates, the relative position of the rotor
and the stator windings change. Either the rotor or the two
stator windings together can be used as the primary of the
rotary transformer and the secondary will then produce an
analog-voltage corresponding to the shaft position.
RL100 Resolver—The Workhorse of the
Industry
AVG Automation's model RL100 resolver is the most rugged
resolver in the industry today. AVG Automation has over
25,000 of these resolvers operating with extreme reliability in
highly demanding applications in automotive, can-manufac-
turing and packing industries. Rugged, industrial housing,
heavy-duty, double-row, ball bearing and an internal flexible
coupling lend to an extremely reliable design.
