Product Description:

The R32SSNA-R2-NS-NV-05 is a servo motor built by Pacific Scientific as part of the R Servomotors series. In industrial automation it is selected to drive small conveyors, index tables, and pick-and-place arms where accurate speed regulation and repeatable positioning are required. By combining electronic commutation with a brushless construction, the motor provides a compact electromechanical actuator that couples directly to the load and interfaces with a matched amplifier through standard three-phase power leads and signal connectors. It is suited to duty cycles that require frequent starts, stops, and direction changes on compact motion axes.

Its continuous stall capability is rated at 1.7 Nm, meaning the shaft can apply this torque indefinitely without exceeding thermal limits when locked in position. For rapid acceleration or brief overloads, the device delivers up to 4.40 Nm of peak torque, allowing headroom for start-ups and transient load spikes. The housing measures 3.25-inch square, which simplifies installation into machinery that follows NEMA-style mounting patterns. Rotor inertia is specified at 0.071 kg·m² × 10⁻³, and this low value supports quick speed changes while keeping control loop gains moderate. Torque production is enhanced by a magnet stack made from rare-earth samarium cobalt, a material that supplies high flux density without demagnetization at typical operating temperatures.

Mechanical construction follows the standard housing style and uses a stack length of 2 inches to achieve the listed power density. Positional data is returned to the drive through a size 21 frameless resolver of the transmitter type, providing rotor position information with analog sine-cosine signals, and no secondary feedback device is fitted. Because the design is supplied without a brake, external holding methods are required when power is removed. The motor is built without a shaft seal, so it should be mounted where splashing liquids or airborne contaminants are controlled.
