Product Description:

Pacific Scientific manufactures the R35GENH-R2-NS-NV-00 servo motor as a member of the R Servomotors series. This brushless unit converts drive current into controlled rotary motion for indexing tables, packaging axes, and pick-and-place mechanisms in automated cells. By integrating closely with digital drives, the motor supplies repeatable torque across a compact frame, allowing accurate load positioning while maintaining the cycle times required in industrial automation.

The continuous stall capability is 3.8 Nm, providing a stable holding force when the shaft is energized but stationary; this rating indicates how much load the motor can support without overheating under locked-rotor conditions. During rapid accelerations, it can deliver a peak of 10.1 Nm, giving additional headroom for overcoming inertia and friction. The stator and mounting flange form a 3.25" square envelope, so the motor fits standard NEMA-type layouts without adapter plates. Axial length is kept to 5 inches, an important consideration when space behind the load is limited. Rotor inertia is only 0.13 ×10⁻³ kg·m², which lowers the time required to reverse direction and simplifies tuning of the velocity loop in servo drives.

Performance is reinforced by a rare-earth magnet stack built from samarium cobalt, giving high magnetic flux density and thermal stability. Position data are returned through a frameless resolver of transmitter type, size 21, enabling absolute feedback without delicate optical components. The motor attaches with English mounting, matching inch-based bolt circles common on North American machinery, and its standard winding balances current demand with thermal rise for general-purpose duty. There is no integrated brake, shaft seal, or secondary feedback channel.
