Ultra
Performance Resolvers
Housed-Brushless Resolvers
Our brushless construction uses a rotary transformer to pass
the reference signal to the rotor. This design eliminates
the normal brushslop ring sliding contact used in conventional resolvers.
Since the brush and slip ring are life limiting components and can
be a source of noise in harsh environments, the transformer coupled
units enhance reliability and performance.
Industrial Frameless Resolvers
Our brushless resolvers are the ideal position feedback transducer
for brushless motors, robots and direct drive motors in precision
rotary platforms and similar servo applications. They are rugged,
reliable, provide absolute position information and are able to
operate at 155 degree Celcius and are impervious to most particulate
and liquid process contaminants.

The industry standard Size 11 resolver series has its own
precision bearing system, making it ideal for coupling mounting.
Its brushless construction uses a rotary transformer to
pass the reference signal to the rotor -eliminating components
that can limit life and cause noise. Series 11 has excellent
angular accuracy and repeatabilty. Alternatively,
the R11 shaft accepts pinions or pulleys for use in rack
and pinion or cable measuring systems. Series 11 resolvers
are rated up to 155C for high temperature applications.

Harowe R25 Heavy Duty resolvers are designed for reliability
in adverse operating conditions. Brushless resolvers
are the better choice over encoders for applications that
involve very high temperature, vibration and shock and dirty
environments. Unlike similar duplex-bearing packages,
the R25 uses a front-and-rear bearing arrangement that provides
two to three times the radial load bearing capacity and
up to ten tomes the L10 life of a package with duplex bearings.
Rated for ruggedness with IP65 protection, 125C continuous
duty, shock resistance to 200g and vibration resistance
to 40g.

The 700 Series provides maximum accuracy and minimum error
for demanding position and velocity applications such as
robotics. HaroMax resolversT sizes 15 and 21 feature
a tooth-wound design that reduces electrical error 50 percent
less than that of a standard resolver. and incorporates
windings that are manufactured and installed completely
automatically. The automatic installation provides
the least amount of part-to-part variation for the greatest
consistency. Able to operate up to 200 C with
high shock and vibration resistance.
