Product Description:
The R32GMNC-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific for the R Servomotors series. As a rotary actuator, it is installed in industrial automation cells where precise speed and position control are required for conveyors, gantries, and small indexing stations. The motor converts regulated drive current into mechanical torque, while its resolver feedback keeps the control loop aligned with commanded motion profiles. This closed-loop arrangement allows the connected drive to correct variations caused by changing loads and maintain controlled movement throughout repetitive operating cycles.
This model supplies a continuous stall torque of 1.7 Nm, meaning it can maintain that torque without exceeding its thermal limit. During acceleration or short overload events, it reaches a peak output of 4.40 Nm, providing additional torque for rapid starts. The rated speed of 4000 rpm is the maximum steady-state shaft velocity under nominal voltage and temperature conditions. Rotor inertia is 0.071 kg·m² × 10⁻³, a low value that helps the drive command quick reversals with minimal overshoot. The compact 3.25-inch square frame allows the motor to fit within the tight mechanical spacing common in electronics assembly and light packaging equipment. Its proportions also support direct integration into compact axes where available mounting space is limited.
The magnetic circuit uses rare-earth samarium cobalt material, increasing torque density without enlarging the housing. A metric mounting face and Housing Style C provide standardized mounting features for attachment to compatible machine structures. The shaft end has no shaft seal, so the motor is best suited to installations where external contaminants will not reach the shaft opening. Position feedback is delivered through a frameless resolver, size 21, which supplies rotor-angle information to the servo drive. The motor does not include secondary feedback or a holding brake, reducing its rotating and overall mass. Its two-inch stack length and standard winding support high-cycle machinery, while an external clamp or drive-generated torque can secure the load when power is removed.
