Product Description:
Pacific Scientific R22HENA-R1-NS-NV-11 Servo Motor delivers reliable 0.29 Nm torque at 240V AC with precise position control via a compact frameless resolver. It is produced specifically for demanding motion tasks as it sustains 2.7 Arms stall current without overheating which makes it ideal for applications that require accuracy, continuous force and space-efficient integration.
The R22HENA-R1-NS-NV-11 servomotor is capable of sustaining a rotational pace of 8000 revolutions per minute when it operates under standard electrical input conditions of 240 volts alternating current or 320 volts direct current. As the rotor spics, it encounters resistance proportional to its speed due to internal friction from air and mechanical structures which is quantified as 0.005 Newton-meters per thousand revolutions per minute that represents the amount of braking force it generates. It is equipped with a military-standard electrical connector placed at the rear which comes pre wired with 18 inches long cables for streamlined installation. The amount of voltage it produces per unit of angular velocity is 0.12 volts root mean square for every radian per second which reflects how effectively it generates back EMF as it spins. It exhibits low internal stickiness with a static friction of 0.02 nm which makes it well suited for precision applications where small and delicate motions are crucial.
This R22HENA-R1-NS-NV-11 servomotor stator winding type is labeled as H which refers to a specific configuration in the coil winding that influences current handling, resistance and how it behaves under various loading and voltage conditions. It produces 0.2 nm of turning force for every ampere of root-mean-square current delivered to it and it has a thermal resistance of 1.43 degrees Celsius per watt which helps it operate reliably under sustained loads without overheating.
Frequently Asked Questions about R22HENA-R1-NS-NV-11:
Q: Why does the R22HENA-R1-NS-NV-11 use a frameless resolver instead of an encoder?
A: A frameless resolver offers superior durability and noise immunity in harsh environments. It ensures accurate shaft position feedback even under extreme temperatures and vibrations.
Q: How does low viscous damping improve performance in the R22HENA-R1-NS-NV-11 motor?
A: Low viscous damping reduces power loss at high speeds. It allows the motor to accelerate faster and maintain smoother, energy-efficient operation.
Q: What advantage does the H-type winding offer in this servo motor?
A: The H winding configuration optimizes resistance and inductance for high-speed performance. It also supports stable torque delivery across a wide voltage range.
Q: How does the low static friction of 0.02 Nm benefit precision tasks?
A: Minimal friction reduces resistance during startup, enabling ultra-fine motion control. This feature is ideal for micro-positioning and high-accuracy tasks.
Q: Why is the R22HENA-R1-NS-NV-11 servo motor suitable for space-constrained systems?
A: Its compact frame and rear-exit cabling simplify installation in tight assemblies. The frameless feedback system further reduces footprint without compromising performance.
