Product Description:

The R65GENA-R2-NS-NV-00 servo motor is manufactured by Pacific Scientific and sits within the R Servomotors series. As an electrically commutated AC motor, it provides closed-loop motion control for industrial automation axes that require repeatable torque and speed regulation. The unit functions as a servo actuator that converts drive current into precise rotary motion for packaging machines, material-handling gantries, or positioning tables. When paired with a compatible servo drive, it supports controlled starts, stops, and speed changes across repetitive machine cycles.

The motor has a continuous stall capability of 13.6 Nm, allowing steady load holding without overheating, while short bursts can reach 33.3 Nm of peak torque for acceleration events. Rotor inertia is 1.26 kgm²×10⁻³, which supports quick reversals while helping the axis remain stable under changing load conditions. At the rated speed of 2000 rpm, the standard winding delivers its nominal mechanical output. Field strength is supplied by Rare earth (samarium cobalt) magnets, which offer high magnetic energy and good thermal stability. Primary position feedback is provided by a frameless resolver of transmitter type, size 21, so the drive receives shaft-angle data without integral bearings. This combination of torque, speed, and feedback makes the motor suitable for servo applications that need accurate motion response.

The frame measures 5.75" square, and the active stack length is 5 inches, so the motor fits applications that are constrained in width but can accommodate deeper housings. The motor uses a standard housing style and standard windings, which keeps the configuration straightforward for general machine integration. Mounting follows the English bolt pattern common on North American equipment, and there is no shaft seal, so the installation area must remain free of fluid ingress. Because the motor does not include a holding brake or secondary feedback, position retention after power removal must be handled by the drive system or external mechanical means.
