Product Description:

The R63GENA-R2-NS-VS-00 servo motor is manufactured by Pacific Scientific as part of the R Servomotors series. Classified as a servo motor, it is intended for closed-loop speed and position control in automated machinery where compact electromechanical drives are required. By integrating with a suitable drive amplifier, the motor converts three-phase electrical power into controlled rotary motion, allowing conveyors, indexing tables, and pick-and-place axes to follow programmed motion profiles within an industrial control system.

The motor has a continuous stall capability of 8.3 Nm, indicating the torque the rotor can sustain indefinitely without overheating when locked. For short acceleration intervals, it can deliver up to 20.5 Nm, providing the headroom needed to overcome static friction or accelerate high-inertia loads. The rated mechanical output speed is 3400 RPM, so the motor can track moderate- to high-speed command signals without gear reduction. Rotor inertia is 0.81 kg·m² × 10⁻³, which balances quick response with damping for stable servo tuning. This dynamic behavior is supported by magnets made from rare earth samarium cobalt, a material that maintains high flux density across a broad temperature range.

Mechanical integration is simplified by the 5.75" square frame that matches English mounting patterns, allowing installation in legacy Pacific Scientific layouts. The standard housing resists contamination, while a Viton shaft seal limits oil ingress at the output end. Because the motor is supplied without a holding brake, external locking devices are required when power-off holding is essential. Position feedback is provided by a frameless resolver, transmitter type, size 21, eliminating the need for a secondary encoder. The electromagnetic core is stacked to a depth of 3 inches, and the standard winding option simplifies drive setup.
