Absolute Rotary Sensing
1986 Series
The Gemco Series 1986 Resolver
has been the preferred source
for rugged and accurate rotary
positioning in a variety of industrial
applications.
The brushless resolver works on the
same principle as a rotary transformer
to couple power in the rotor. The
internal brushless resolver has three
separate windings: a reference
winding, a SIN winding and a COS
winding.
The reference winding is excited by
an AC voltage. The SIN and COS
winding are set 90° apart and provide
two different output voltages whose
ratio represent absolute position of
the shaft.
The advantage of resolver
transducers over other rotary position
products is that resolvers hold up
better in harsh environments and they
are always absolute, so if power is
lost and restored, the exact position
data will be communicated.
In long cable runs a resolver signal
can typically go much further than
other technologies. Resolvers have
long been the standard rotary position
method in packaging, primary metals
manufacturing, stamping, automotive,
tire and rubber, paper mills and
mining.
Gemco has always been a pioneer
in the design and manufacturing of
“built to order” resolver packages.
We can mechanically and electrically
match any competitor’s package while
improving on the overall design to
enhance the performance, accuracy or
durability.
Through our wide range of materials
for construction and precision gear
reducers we can extend your sensor’s
life many times over.
We offer packages with multiple
sensors and gear reducers in a variety
of materials. We have engineered
special resolver packages with
stainless steel housings, oil filled
packages, high RPM, high resolution,
resolver/encoder combinations and
tach generators.
