Product Description:
The R35KENP-R2-NS-NV-00 is built by Pacific Scientific as part of the R Servomotors series. It is used to deliver closed-loop rotary motion for positioning tables, material-handling axes, and other automated stations that need precise torque and speed regulation. When paired with a compatible drive and resolver interface, the motor can follow repeatable velocity profiles and hold commanded positions under varying load conditions.
The motor develops a continuous stall torque of 3.8 Nm, providing baseline force for static holding or slow-speed feed moves, while a peak torque of 10.1 Nm supports rapid acceleration during indexing cycles. Rotor inertia is only 0.00013 kg·m², so commanded speed changes can be carried out with limited overshoot. A compact 3.25-inch square frame simplifies installation in machinery that follows NEMA-style bolt patterns, and the explosion-proof housing allows operation in hazardous areas where flammable vapors may be present. The model is supplied without a holding brake, uses an English mounting interface, and senses position through a frameless size-21 resolver mounted directly on the shaft for noise-immune feedback.
During continuous rotation, the shaft can reach 4200 rpm, which allows direct coupling to process loads or use with small-ratio gearheads. High-energy magnets made from rare-earth (samarium-cobalt) material maintain flux density at elevated temperatures and support consistent torque as winding temperature rises. A stack length of 5 inches fits medium-duty enclosures while leaving space for power leads and resolver cabling, and the Medium-High winding balances current demand with thermal dissipation so the motor can remain within rated limits without forced cooling. There is no shaft seal and no secondary feedback device, which simplifies use in applications where washdown protection or redundant sensing is unnecessary.
