Benefits of Honeywell Torque
Most Spring Return Torque in a HVAC Actuator, 20
more than competitors

• Fewer Actuators needed for larger dampers
• Example
• 72x60 damper with seals would require
  approximately 150 lb-in of torque
• If a spring returned actuator was needed, it
  would take at least 2 of each competitive
  actuator, whereas ONE Honeywell SR DCA would be
  enough--at a lower cost.

• Use Honeywells medium torque instead of a
  competitors high torque
• Example
• 36x56 damper with seals would require
  approximately 70 lb-in of torque
• If a spring returned actuator was needed,
  competitive actuators would require the use of a
  high torque, whereas Honeywells 88 lb-in SR DCA
  would be enough--at a lower cost.
• Reliable coverage of torque variation in a damper
  load

More Torque
Design Considerations
Benefits
Micro-processor controlled Torque Limitation
Accurately limited driving and stall torque
possible due to control of the sub-motor by a
micro-processor which monitors speed and torque.
Torque output consistent across temperature range
Torque output does not dip at extreme ends of
temperature range.
Convenience in a self-centering shaft adapter.
Allows for easy mounting on shafts up to 1.06
dia. Higher torque actuators operate greater
loads which require that the shaft be centered in
the actuator. Greater shaft clamping force than
alternatives.
High Torque Clamping Shaft Adapter
By calibrating the actuator, model-to-model
variation in timing, driving torque and stall
torque are minimized.
Calibrated Output Torque Limitation
Metal Gears constructed from powdered metal
Powdered metal gear are self-lubricating,
extending life and providing reliable performance
Internal, Stainless Steel, Active Power Spring
Cast aluminum housing encloses and protects gear
train, sub-motor and electronics with fewer parts
needed.
38
Better Performance -Electronic Design
Benefits
Design Considerations
Microprocessor controlled DC Brush-less Motors
Taking advantage of improvement is DC motor
technology, Honeywells microprocessor controlled
sub-motor design allows highest positional
accuracy, efficient power consumption and control
signal flexibility.
Efficient Electronic Circuitry
Less energy consumption per in-lb of torque than
the competition
High Impedance Circuitry
High impedance circuits require very low current
from the input signal. Allows driving more
actuators from a common signal.
Input Signal Filtering
Filtering the signal is a safeguard against
unwanted noise. Actuators would otherwise
respond to very slight fluctuations in signal if
protective filtering is not employed.
Electronic circuit design and layout protects the
actuator against common static and lightning
discharges.
Static Lightning Protection
DC Brush-less motors used in all proportional
DCAs
39
Better Performance - Life Cycles
Design Considerations
Benefits
Metal Gears constructed from powdered metal
Powdered metal gear are self-lubricating,
extending life and providing reliable performance.
Plastic Gears constructed from carbon-filled
plastics
Carbon-filled plastics have more strength and
provide longer life than standard plastic
materials
Ball Bearing Sub-motor
Ball bearings decrease load and wear on
sub-motor.
Customized Stainless Steel, Back-wound Power
Spring
Tested to 60,000 Spring Return Cycles using
Corrosion-proof material which eliminates failure
due to rusting.
Sturdy Aluminum Housing for Spring Return
Cast aluminum housing encloses and protects gear
train, sub-motor and electronics with fewer parts
needed.
40
Better Performance - Consistent Timing
Design Considerations
Benefits
Active Spring allows immediate actuation upon
power-up
Actuator will begin positioning immediately with
the introduction of a signal. No need to wait
for spring to wind before actuator starts to
move.
Micro-processor controlled DC Brush-less Motor
Consistent timing possible due to control of the
sub-motor by a micro-processor which monitors
speed and torque.
Load independent
Consistent Timing which is Load and Voltage
independent. Timing stays the same over entire
temperature and voltage ranges.
Voltage independent
Reduces stresses in gear train and decreases wear
due to backlash. Provides a longer-lasting
actuator.
Optimized Gear Train
41
Better Performance - Reliable Control
Design Considerations
Benefits
Computerized Operational Check uses calibration
method to eliminate mechanical tolerances
By calibrating the actuator, model-to-model
variation in timing, driving torque and stall
torque are minimized.
Line Noise can cause unwanted fluctuations in the
position of the actuator. Filtering any noise
out of the input signal results in better
positional stability.
Filtered Input to reject noise
Honeywell uses two separate position feedback
methods (feedback potentiometer and counting
motor commutations). This ensures the most
accurate position tracking in event of power or
signal loss.
Redundant Position Feedback
Accurate positioning from floating signal
Monitoring the duration of the floating control
signal and driving in response to the duration of
the signal.
Using Honeywells Control Expertise, we have
achieved unmatched positional accuracy
repeatability in controller and actuation
performance.

Actuator Selection

• Selection/Sizing
• Typical Applications
• Exercises

44
Actuator Selection

• Deciding which actuator will best fit your damper
  needs can seem difficult.
• There are simple steps which help you find the
  correct actuator for your application.
• Start by asking the right questions.

45
Questions

• Is fail-safe required?
• An actuator which is capable of moving the damper
  to a predetermined point when de-energized is
  considered to be fail-safe.
• Spring return actuators are the primary means of
  providing fail-safe.

46
Questions

• What is the torque required?
• Actuators are rated with an output torque.
• The amount of torque required is dependant upon
  the damper load.
• The damper load is calculated from the
  characteristics of the damper and the application.

47
Questions

• What is the control signal required?
• The actuator receives a control signal from a
  controller.
• The actuator must be compatible with the control
  signal in order to respond.
• Many times, the power supply voltage is also
  considered along with the control signal.

48
Questions

• Other features?
• Does the application call for auxiliary switches?
• Is feedback required?
• Are there special mounting considerations?

49
Actuator Sizing

• Sizing of an actuator is essentially determining
  the amount of torque needed to operate the
  damper.
• There are several inputs required to calculate
  the damper size.
• Type of damper
• Torque Multiplier
• Face velocity
• Pressure Differential

50
Actuator Sizing - Step 1

• Determine the Rated Torque Multiplier
  (in-lb/sq.ft.)
• Obtain from damper manufacturer
• Or, use following table for industry standards

51
Actuator Sizing Step 2

• Determine the Damper Area
• For round dampers use
• For rectangular dampers use

52
Actuator Sizing Step 3

• Calculate the torque by multiplying the area by
  the torque multiplier.
• The product is the Damper Torque Requirement.
• Recommend adding a safety factor.
• Multiply the Damper Torque requirement by the
  safety factor.
