Product Description:

The R63GENA-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific and falls within the R Servomotors series. As a closed-loop actuator, it converts electrical drive commands into controlled rotary motion for packaging lines, pick-and-place gantries, and other automation axes that demand repeatable positioning. It is intended for machines that need consistent motion control without requiring unusually large motor dimensions. Stable feedback and predictable torque response make it suitable for frequent starts, stops, and indexing moves.

This model delivers a continuous stall torque of 8.3 Nm, allowing the axis to hold a load without overheating when stationary. During rapid accelerations, it can reach a peak torque of 20.5 Nm, giving additional margin for overcoming inertia and friction at startup. Rotor inertia is 0.81 kg·m² × 10⁻³, which helps the drive achieve quick speed changes while maintaining smooth motion. A rated speed of 3400 RPM allows sustained operation under nominal bus voltage and load. The magnetic circuit uses rare earth samarium cobalt, which supports high torque density in a compact motor package. Overall size is based on a 5.75-inch square frame, matching common gearhead and flange patterns used in North American machinery. This combination supports responsive axis behavior without requiring a large installation envelope.

The mechanical stack length measures 3 inches, balancing torque output with the available depth in multi-axis assemblies. Position feedback is supplied by a frameless resolver size 21, providing rotor angle data to compatible amplifiers without the fragility associated with optical encoders. All mounting interfaces follow the English bolt circle convention, which matches inch-based machine layouts commonly used in North America. The motor is supplied without a holding brake, uses a standard winding, and has no shaft seal. Housing style is standard, secondary feedback devices are not fitted, and the assembly relies on natural convection for heat removal during continuous duty. This arrangement suits applications where braking and enclosure sealing are handled elsewhere in the machine.
