Product Description:

The R63GENP-R2-NS-VS-00 is a brushless servo motor produced by Pacific Scientific within the R Servomotors series. It is intended for precision motion in industrial automation where consistent torque delivery and accurate feedback are required for coordinated axes. The unit combines a sealed stator, a rare-earth magnet rotor, and a resolver so that a matched drive can command velocity or position loops without external gearing or manual calibration.

This model supplies a continuous stall torque of 8.3 Nm, allowing the axis to hold a load when stationary without overheating, while the peak capability rises to 20.5 Nm for acceleration or short overloads. At its rated mechanical speed of 3400 rpm, the motor operates within the thermal range set by its standard windings and 3-inch stack length. The enclosure is classified as explosion-proof, enabling installation where ignitable vapors may be present. Total reflected inertia is limited to 0.81 kg·m² × 10⁻³, supporting fast response when paired with a low-inertia load. English-pattern mounting holes fit North American machine interfaces, and the design is supplied without a holding brake, so external locking devices must be used if power-off positioning is necessary.

Physical dimensions include a frame that measures 5.75-inch square, a size that fits standard NEMA adapters while leaving space for cabling beneath the conduit box. A Viton shaft seal keeps process dust and fluid out of the bearings, and the rotor uses rare-earth samarium-cobalt magnets for high energy density over a wide ambient range. Primary commutation and positioning are provided by a size 21 frameless transmitter-type resolver, and there is no secondary feedback channel. The electrical and mechanical configuration is fixed for this build.
