Group 11 Rotary Damper Drives and Actuators
Mechanical Features
 Drive Train:
Durable and Efficient
Beck’s durable gear train
maintains accurate, consistent
control element positioning even
under the demanding conditions
of an active control loop.
- Gear trains employ a
unique, all spur gear
construction of heat-treated
alloy steels and
ductile iron.
- Efficient, wide-face spur gearing virtually eliminates wear-induced
backlash and positioning inaccuracies.
- Durable design provides up to 4 days of protection against
intermittent or extended accidental stalls.
- Integral self-locking mechanism ensures that drives hold a load
with the motor de-energized.
 Manual Handwheel:
Convenient Manual Control Without Declutch
An easy-to-turn, spoke-free
Handwheel is incorporated into the
Group 11 design to allow manual
operation during installation or power
outages.
- Move valves and dampers to any position smoothly and easily
without power, even under full load conditions.
- Mechanical stops in housing prevent manual overtravel.

Housing:
Superior Protection with Convenient Access to Components
Beck drives feature a cast aluminum
body with individual compartments to
protect components from moisture
and dirt, and allow easy access for
installation and calibration.
- Precision-machined aluminum
alloy castings with corrosionresistant
poly-urethane paint
provide a rugged, dust-tight,
weatherproof NEMA 4X
enclosure.
- Individual compartments protect all major components: Motor,
DCM, CPS-2, gear train and installation wiring terminal board.
- Each compartment can be accessed without exposing other
components.
 Mounting Versatility:
Mount in any Orientation for Greater Installation Flexibility
Group 11 Beck drives are designed to
be mounted in any convenient
position. The no oil bath design
eliminates the potential for leaks.
As long as housing compartments remain accessible, there are no mounting orientation limits.
