Product Description:

The R67GENA-R2-NS-VS-00 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. It serves as an electromechanical actuator that delivers controlled torque and speed to automated machinery stations. By accepting three-phase drive power and providing resolver feedback, the motor links directly to digital amplifiers that close the velocity and position loops used in packaging, material handling, and metal-cutting equipment. This arrangement supports repeatable axis control during indexing, feed, and synchronized motion tasks. The unit has a standard housing, and the lack of an internal brake means the application must rely on external holding methods when power is removed.

The motor occupies a 5.75-inch square frame, giving it a compact footprint that aligns with NEMA-style mounting flanges. A continuous stall torque of 19.9 Nm is the maximum steady load it can hold without rotor movement, while the rotor’s reflected inertia is 1.72 kgm² × 10⁻³, which supports fast acceleration and deceleration profiles. When driven to its rated speed of 1400 rpm, the unit maintains thermally stable operation, and during short duty bursts it can reach a peak torque of 48.9 Nm. Those operating values suit axes that need stable holding capability at low speed and additional torque during brief motion peaks.

The motor uses a frameless transmitter-type resolver, size 21 for primary feedback, providing position information to the drive without battery support. The laminated stack extends to 7 inches, increasing active iron length so flux from the rare-earth samarium-cobalt magnets is used effectively across the rotor and stator. Sealing is provided by a Viton shaft seal that resists oils and mild solvents, and the motor mounts with an English bolt pattern that matches inch-based machine layouts. Housing style and winding are standard, and the motor does not include secondary feedback.
