Product Description:

The R24SSNA-RT-NS-NV-03 is a rotary servo motor from Pacific Scientific, delivered in the R Servomotors series. Designed for controlled motion on packaging, assembly, and material-transfer axes, it turns commanded current into accurately regulated shaft rotation that supports repeatable positioning routines. A compact round frame lets the unit fit where square bodies are impractical and simplifies cable routing, giving machine builders an electric alternative to pneumatic or hydraulic actuators in tight spaces.

During continuous operation the motor develops 1.1 Nm of stall torque, allowing it to hold or drive a load indefinitely at rated current. When higher acceleration is required, it can momentarily reach 3.07 Nm of peak torque before thermal limits intervene. Dynamic response is helped by a rotor inertia of 0.021 × 10⁻³ kg·m², so speed can be changed quickly without excessive control effort. The electromagnetic core is wrapped in a 2.0" OD (Round) stator that keeps mounting holes concentric with the load. Inside, rare earth (samarium cobalt) magnets provide high flux density and temperature stability, which preserves torque output over extended duty cycles and reduces demagnetization risk.

The active stack length is 4 inches, keeping the motor short enough for multi-axis clusters. Its Standard housing style supplies the basic mechanical envelope without added flanges or special coatings. Because there is no shaft seal, use in splash zones requires an external barrier. Feedback hardware is limited to the primary channel; there is no secondary device for redundant position reporting. Finally, the unit ships without a holding brake, so position retention during power-off must be handled by the drive or an external clamp.
