Product Description:

The R65GEAP-R2-NS-NV-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. It is intended for closed-loop motion axes that require precise torque control in industrial automation cells, pick-and-place gantries, and packaging equipment. By converting electrical drive commands into controlled rotational motion, the unit positions mechanical loads accurately and supports coordinated multi-axis profiles.

This model delivers a continuous stall torque of 13.6 Nm, giving the drive enough margin to hold loads without loss of synchronism at zero speed. For starting or rapid acceleration, it can reach a peak torque of 33.3 Nm, a short-term capability that lets the application overcome frictional or inertial spikes. The rated speed is 2000 rpm, so a gearbox or belt stage can be selected knowing the motor’s steady mechanical output. Rotor inertia is only 1.26×10⁻³ kg·m², minimizing servo lag during direction changes. An explosion-proof housing allows installation in classified areas where flammable vapors may be present. A factory-mounted 24 V DC brake locks the shaft when power is removed, preventing uncommanded motion on vertical or safety-critical axes.

The physical package measures 5.75-inch square across the mounting face, and the stator stack is 5 inches long, yielding a form factor that fits standard NEMA adapters while keeping overall mass moderate. Magnetic flux is produced by rare earth (samarium cobalt) material, which supports high torque density and stable demagnetization characteristics over a wide temperature span. The frameless size-21 resolver provides absolute position feedback, while no secondary transducer is installed, simplifying cabling. English mounting threads match common American machinery plates, and the shaft is supplied without a seal, so an external barrier should be used where fluid ingress is possible. Winding is the standard resistance and inductance option for this frame, giving predictable compatibility with the manufacturer’s matched drives.
