1986 Series

Absolute Rotary Sensing

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.
