Product Description:

The R65GENA-R2-NS-VS-00 servo motor is produced by Pacific Scientific and belongs to the R Servomotors series. As a brushless AC servo motor, it delivers regulated torque and position control for automated machinery, enabling coordinated axis movement in packaging, material handling, and assembly cells. It is intended for closed-loop motion tasks that require repeatable positioning, stable speed regulation, and quick reversal during continuous production. This motor type is typically used with a servo drive that closes the current, speed, and position loops during operation.

It provides a continuous stall torque of 13.6 Nm, allowing the motor to support load without rotor motion, while its peak torque capability of 33.3 Nm supports short-term acceleration during rapid indexing. The rated speed of 2000 rpm allows continuous shaft rotation at the standard winding temperature rise. A square frame that measures 5.75 inches on each side simplifies installation on machines that follow common NEMA footprints. Rotor inertia of 1.26 kg·m² × 10⁻³ provides a balance between responsive acceleration and position stability. Primary feedback is provided by a size-21 frameless resolver, and no secondary feedback device is installed.

The motor uses rare earth (samarium cobalt) magnets to maintain magnetic flux under elevated thermal loads, and its Viton shaft seal helps limit oil or dust ingress along the output shaft. An overall stack length of 5 inches keeps the unit compact, and the English mounting interface uses threaded holes that match imperial fasteners. The housing style and winding type are standard, and the factory configuration omits an internal holding brake to keep inertia and mass low during high-speed cycles. Because the resolver is the only feedback element, wiring remains simple and there is no secondary feedback connection to route.
