Product Description:

The R65GMNA-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific within the R Servomotors series. This rotary unit converts controlled electrical power into precise mechanical torque and speed for positioning tasks in automated machinery, packaging lines, and material handling equipment. When paired with a compatible drive, it supports controlled starts, stops, and speed changes during repeated machine cycles. This makes it suitable for axes that require stable motion and accurate positioning during normal operation.

At its core, the motor delivers a continuous stall torque of 13.6 Nm, ensuring consistent force when the shaft is held motionless under load. For short duty surges, it can reach a peak torque of 33.3 Nm, giving equipment a margin for rapid acceleration. A rated speed of 2000 rpm matches common motion profiles in indexing tables and gantry axes. Rotor inertia is contained to 1.26 × 10⁻³ kg·m², so the drive responds quickly to velocity commands without overshoot. The square frame measures 5.75 inches on each side, allowing direct substitution into legacy Pacific Scientific mounts. A standard housing and winding set keep thermal behavior predictable, while the design is supplied without a holding brake to minimize length and mass.

Position feedback is provided by a frameless resolver transmitter in size 21, giving rotor angle feedback for closed-loop drives without adding encoder height. Magnetic flux is generated by rare earth samarium cobalt material, which maintains high coercivity at elevated temperatures. The laminated core is built to a 5-inch stack length, preserving compact overall depth. Mechanical attachment follows metric mounting conventions, easing integration with European gearboxes and couplings. There is no shaft seal, so the motor must be installed in clean environments or paired with external sealing. Secondary feedback is not included, and the absence of a brake simplifies wiring.
