Product Description:

The R65GENA-NP-RW-VS-02 is a servo motor built by Pacific Scientific for the R Servomotors series. As a rotary actuator, it converts commanded current into precise shaft motion for indexing tables, pick-and-place units, and other closed-loop automation axes that require rapid torque modulation. The motor follows the manufacturer’s standard housing style and uses an English mounting format, making it a drop-in option for retrofits or motion stages built around this series.

This model develops a continuous stall torque of 13.6 Nm, meaning it can hold that load indefinitely without exceeding its thermal limit. The square frame measures 5.75 inches on each side, which sets the flange pattern and the cross-section for cabinet or robot arm layouts. Application responsiveness is influenced by the rotor inertia of 1.26 × 10⁻³ kg·m²; that modest value permits quick acceleration while helping resist overshoot in position loops. A rated speed of 2000 rpm supports the motor’s continuous power range for conveyors or feeders that run in the mid-speed band. A Viton shaft seal is fitted to restrict oil, dust, and coolant from entering the bearing cavity, so the unit can be mounted in mildly contaminated environments without external sealing hardware.

Dynamic events are covered by a peak torque capacity of 33.3 Nm, allowing the drive to clear momentary inertia mismatches or indexing spikes without tripping protections. The magnetic circuit uses rare-earth samarium cobalt, which produces high flux density in a compact rotor and maintains resistance to demagnetization over a wide temperature span. Performance length is set by a 5-inch stack, giving a predictable axial envelope when matching gearboxes or couplings. The motor is supplied without a holding brake, so position retention under power-off conditions must be handled by the machine’s mechanical design or by drive torque when the controller remains energized.
