Product Description:
The R33GEBC-R2-NS-NV-00 is a brushless AC servo motor manufactured by Pacific Scientific for the R Servomotors series. As a rotary actuator, it forms the final drive element in motion loops that require closed-loop position, speed, and torque control. When paired with a matching power stage and controller, the unit converts commanded current into precise mechanical rotation, supporting automated packaging lines, electronics assembly equipment, and light material-handling gantries that must index, dwell, and repeat within tight tolerances.
The square mounting face measures 3.25-inch on each side, and the English mounting pattern simplifies drop-in replacement in existing fixtures. A continuous stall capability of 2.5 Nm supports steady axial or radial loads, while transient demands are absorbed with a peak limit of 6.54 Nm. The rotor reaches its rated velocity of 3000 rpm, allowing direct coupling to moderate-speed conveyors and feeders. System responsiveness is helped by an inertia of 0.093 kg·m² × 10⁻³, balancing quick acceleration against overshoot. Housing style C encloses the stator stack, and the standard winding provides thermal performance consistent with typical industrial duty cycles.
A 100 V dc holding brake locks the shaft when power is removed, preventing back-driving on vertical or safety-critical axes. Position data is supplied by a frameless resolver size 21, and no secondary feedback channel is present, which reduces cable count and interface complexity. The magnetic circuit uses rare-earth samarium cobalt material to raise torque density while maintaining thermal stability. A 3-inch stack length defines the active iron section, and the absence of a shaft seal calls for protection from fluids in wash-down environments. These attributes complete the electromechanical profile.
