We were wondering if a Hitec H22HD servo could swing a 3.6 arm in a circular fashion in a side to side motion with any success. We're kind of at a loss at how to calculate it. The specifications are:


Control System: +Pulse Width Control 1500usec Neutral
Required Pulse: 3-5 Volt Peak to Peak Square Wave
Operating Voltage: 4.8-6.0 Volts
Operating Temperature Range: -20 to +60 Degree C
Operating Speed (4.8V): 0.19sec/60° at no load
Operating Speed (6.0V): 0.15sec/60° at no load
Stall Torque (4.8V): 42 oz/in (3.0 kg/cm)
Stall Torque (6.0V): 51 oz/in (3.7 kg/cm)
Current Drain (4.8V): 7.4mA/idle and 160mA no load operating
Current Drain (6.0V): 7.7mA/idle and 180mA no load operating
Dead Band Width: 5usec
Operating Angle: 40 Deg. one side pulse traveling 400usec
Direction: Clockwise/Pulse Traveling 1500 to 1900usec
Motor Type: Cored Metal Brush
Potentiometer Drive: 4 Slider/Direct Drive
Bearing Type: Top/Resin Bushing
Gear Type: Heavy Duty Resin
360 Modifiable: Yes
Connector Wire Length: 11.81" (300mm)
Dimensions: 1.57" x 0.79"x 1.44" (40 x 20 x 36.5mm)
Weight: 1.52oz (43g)

Any help as to how we would calculate the feasibility of such an application would be very much welcome.

Thank you in advance.
