Product Description:

The R33GSNC-HS-NS-NV-02 is a servo motor manufactured by Pacific Scientific within the R Servomotors series. Designed for closed-loop motion systems, the unit converts drive current into accurate rotational movement so that pick-and-place modules, indexing tables, and other automated mechanisms can position loads with repeatable precision. It fills the role of the mechanical actuator inside an electromechanical axis, accepting commands from a compatible amplifier and returning speed feedback for drive regulation in industrial automation cells.

It occupies a compact 3.25-inch square frame, allowing direct mounting where installation space is limited. The rotor can deliver a continuous stall output of 2.5 Nm, giving machinery a stable holding capability during dwell periods, while a momentary ceiling of 6.54 Nm supports acceleration bursts without demagnetization. At the rated operating point of 3000 rpm, thermal rise stays within design limits thanks to a standard winding set optimized for balanced copper fill. Dynamic response is aided by a reflected inertia of only 0.093×10⁻³ kg·m², which reduces drive effort during reversals. The unit is shipped without a holding brake, so external clamping must be used when power-off torque is required, and its windings follow the standard configuration offered across the series.

A magnet stack built from rare-earth samarium cobalt magnets gives high energy density and consistent flux at elevated temperatures. Position information is returned through Hall sensors, and no secondary feedback element is installed, simplifying cable routing. The active iron extends over a 3-inch stack, enclosed in the motor’s housing style C construction that aligns with the manufacturer’s dimensional code for conduit box orientation. There is no shaft seal, so the installation must prevent fluid ingress at the coupling interface. This layout keeps feedback wiring simple and suits installations that protect the shaft end from fluid exposure.
