Product Description:

The R63GENP-R2-NS-NV-00 servo motor is produced by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion systems, the unit converts electrical input from a matched drive into regulated shaft torque and speed for conveyors, form-fill-seal machines, and robotic joints. By combining brushless construction with resolver feedback, it supports accurate positioning while keeping maintenance requirements low.

Its continuous stall capability is 8.3 Nm, meaning the shaft can hold that torque indefinitely without exceeding thermal limits. When short bursts of force are demanded, the drive can deliver 20.5 Nm, giving machinery headroom for acceleration or sudden load changes. Rotor inertia of 0.81 kg·m² × 10⁻³ allows quick speed transitions while still damping minor load disturbances. A rated speed of 3400 rpm aligns with typical 200 Hz inverter outputs and supports direct coupling to moderate-ratio reducers. The housing is explosion-proof, so internal arcs or hot components are contained for use in Class I Division 1 environments. The motor uses a 5.75-inch square frame for mounting on existing NEMA brackets. It is supplied without a holding brake, and there is no shaft seal, which reduces friction but limits use where fluid ingress is expected.

Mounting hardware follows the English pattern, so threaded holes and pilot diameters match inch-based fixtures common in North American machinery. Torque is produced by a rare earth samarium cobalt magnet set that maintains flux at elevated temperatures and resists demagnetization. The laminated core is 3 inches long, which helps preserve power density in compact servo installations. Position data are returned through a size 21 frameless resolver, a transmitter-type sensor that withstands vibration better than optical encoders. The winding is standard, so the drive can use catalog current limits without special tuning, and no secondary feedback device is fitted, which simplifies cabling.
