Product Description:

The R33GSNC-HS-NS-NV-03 is a Pacific Scientific servo motor in the R Servomotors series. In automated machinery, it acts as the main rotary actuator, taking commands from a matched drive and converting them into accurate mechanical motion for indexing tables, material-handling axes, or light process lines. Its square 3.25-inch frame allows direct coupling to planetary gearheads or pulleys while maintaining a compact footprint for multi-axis assemblies.

The motor can produce a continuous stall torque of 2.5 Nm. This is the sustained torque available when the shaft is energized but held stationary, so loads can be sized without exceeding thermal limits. A 3.25-inch square frame size sets the mounting face and bolt pattern for interchangeability with other NEMA-style motors. The rated mechanical output reaches 3000 rpm, providing a baseline speed point for selecting drive ratios and feedback resolution. During rapid accelerations, it can reach a peak torque of 6.54 Nm, providing headroom for static friction or momentary load spikes. Dynamic response is supported by a rotor inertia of 0.093 kgm² × 10⁻³, which allows fast velocity changes with modest current demand.

The cylindrical aluminum enclosure uses housing style C, and the magnetic circuit relies on rare earth (samarium cobalt) material for high energy density and stable temperature performance. Rotor position is returned to the drive through Hall sensors, and no secondary feedback element is fitted, which simplifies the cable set. The motor has no integral brake, so holding torque must be supplied by the drive or an external device when the axis is stopped. There is no shaft seal, so the motor should be used where liquid ingress is not expected. The 3-inch stack length balances torque and overall weight, and the standard winding type supports conventional drive voltages without special tuning.
