Product Description:
The Pacific Scientific's manufactured R22GMNA-NP-NS-NV-03 Servo Motor has a 2-inch outer diameter with a round shape for convenience in space-limited installation. This motor is designed for heavy-duty motion control, and its compact size is beneficial in multi-axis applications and precision equipment.
This R22GMNA-NP-NS-NV-03 Servo Motor is constructed using rare earth (samarium cobalt) magnets, which have high magnetic field strengths, provide high torque density, and thermal stability for high-precision positioning systems. The constant stall torque of this servo motor is 0.54 Nm to facilitate operations at sustained load levels without the deterioration of performance. In the case of short-duration, high-load operation, this motor delivers a peak torque of 5.6 Nm, which allows for rapid acceleration and rapid deceleration in motion cycles. This motor's inertia of 0.011 kgm^2x10-3 ensures quick changes in speed and minimum response times. This low inertia is also most suitable for applications involving fast stop-and-start cycles or frequent directional changes. This motor's maximum static friction is 0.019 Nm to provide the least resistance at startup. This servo motor also offers a viscous damping coefficient of 0.0045 Nm/Krpm, which minimizes oscillations and improves stability during operations at changing speeds.
The thermal management of this motor is taken care of by a thermal resistance of 1.43 degrees C/Watt, ensuring efficient heat dissipation in continuous duty cycles. An integrated Positive-Temperature-Coefficient (PTC) thermistor guarantees active thermal protection and prevents this motor from overheating while safeguarding internal components. With a protection rating of IP65, the R22GMNA-NP-NS-NV-03 motor can be used in industries where resistance to contamination is essential. The electrical specifications of this servo motor include a winding inductance of 47 mH for optimizing current control and motor response. This motor's line-to-line torque constant is 0.38 Nm/A to ensure reliable torque output per current input.
