Overview / Design Principle:
The F10 offers compact package dimensions and flying
leads for a low-profile installation. A size 10 servo
ring allows easy mounting and replacement of pancake
resolvers with high tolerance to motor shaft movement
and 360 degrees of adjustment to align the signal outputs
to the shaft position.
A superior optical configuration allows for generous
internal component clearance eliminating potential damage
at high ambient operating temperatures. High temperature
rated grease is standard for extended bearing life.
The use of optically-generated signals for Brushless
DC (BLDC) servo control provides higher accuracy and
reliability by eliminating the hysteresis found in competitive
units with hall-effect sensors, ensuring maximum performance
and reliability of the servo system. Compared to most
pancake resolvers with accuracy of +/-10 arc-min, the
F10 enables superior shaft positioning with accuracy
to ±2.5 arc-min.
Features
and Benefits:
- The F10 design operates up to 120°C. High temperature
materials, innovative phased array sensor technology,
and low current requirements stabilize the output
signals over a wide range of ambient temperature and
output frequencies.
- The F10 mounting configuration allows for direct
pancake resolver replacement featuring a jamb nut
and tethered servo ring

Applications:
The Dynapar brand Series F10 encoder provides high performance,
cost effective feedback for stepper and servo motor
applications.
