Product Description:

The R32SSNA-R2-NS-NV-08 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. In motion-control systems, it supplies precisely regulated rotary power to pick-and-place heads, small indexing tables, and similar axes where consistent speed and position accuracy are required. The unit’s design supports integration with modern digital drives used throughout industrial automation.

Under stalled conditions, the rotor can deliver a continuous torque of 1.7 Nm, indicating the load the motor can hold indefinitely without overheating. The geometric envelope is limited to a 3.25-inch square frame, a size that simplifies layout in multi-axis assemblies. Dynamic response is supported by an inertia value of 0.071 × 10⁻³ kg·m², which helps the drive accelerate and decelerate quickly with less control effort. Torque is produced by a rotor that uses rare earth samarium cobalt magnets, a material that maintains magnetic flux at elevated temperatures. When short bursts of extra force are needed, the motor can withstand a peak torque of 4.40 Nm, providing headroom for rapid indexing or for overcoming static friction during startup.

Position information is supplied by a frameless resolver size 21, providing analog sine-cosine feedback without an additional encoder. The housing is supplied in the standard style, and there is no secondary feedback device, so wiring remains straightforward. Because the construction omits a shaft seal, the motor is intended for clean, dry environments where fluid ingress is not a risk. The electromagnetic stack is 2 inches long, which helps keep the overall motor length short. The model is supplied with no brake, so applications that need power-off holding must rely on mechanical locks or external brakes rather than an internal holding mechanism.
