Product Description:

The Pacific Scientific R35JENC-R2-NS-NV-00 belongs to the R Servomotors series and serves as a torque-controlled actuator for motion axes in industrial automation cells. By converting drive current into tightly regulated rotation, the unit supports coordinated positioning, speed regulation, and indexing functions on conveyors, pick-and-place heads, and similar equipment. This operating profile suits repeatable motion tasks that require stable response during start, stop, and speed-change events.

The motor sustains a continuous stall torque of 3.8 Nm, so it can hold load without overheating when the shaft is locked. Its rated operating velocity is 1700 rpm, matching medium-speed material-handling or conversion lines. A compact 3.25-inch square frame permits dense machine layouts, while the rotor inertia of 0.13×10⁻³ kg·m² limits overshoot during rapid acceleration cycles. Torque is produced with rare-earth samarium cobalt magnets, a material that maintains magnetic strength at elevated temperatures and supports high energy density. English-pattern mounting holes align the flange with North American machinery frames, and the absence of a shaft seal reduces friction in dry, clean environments.

For dynamic surges, the drive can reach a peak torque of 10.1 Nm, giving motion controllers headroom for fast starts or brief load spikes. A stack length of 5 inches balances torque output versus overall motor depth, and the primary feedback device is a frameless resolver, which provides rotor position to the servo amplifier without the fragility of an encoder. The winding is graded as medium, indicating thermal limits and resistance optimized for mid-range current ratings. Housing style C encloses the stator laminations in a smooth cylindrical sleeve, while the factory configuration omits a holding brake, a secondary feedback channel, and a shaft seal.
