Product Description:
The R33HDNC-R2-NS-NV-00 belongs to the R Servomotors series from Pacific Scientific. It is a brushless AC servo motor used in industrial automation to deliver commanded position or velocity with closed-loop accuracy. By combining a compact square frame and resolver feedback, the motor integrates easily with drives that regulate rapid indexing tables, pick-and-place axes, or light machine tools.
The motor can sustain a continuous stall torque of 2.5 Nm, providing a reliable baseline for static load holding without overheating. During acceleration or impact events, it withstands a peak torque of 6.54 Nm, allowing short bursts of extra force before thermal limits are reached. Rotor inertia is only 0.093 kg·m²×10⁻³, so speed changes occur with minimal drive current overshoot, supporting tight servo loops. A rated speed of 6000 rpm pairs with the low inertia to support high mechanical bandwidth in fast-throughput machines. The magnetic circuit uses rare earth (samarium cobalt) material, which raises flux density and helps the compact package reach its torque target. Internal copper is wound in a high-speed winding configuration, matching the elevated base speed to standard bus voltages and limiting back EMF during regeneration.
Mechanical integration is simplified by a 3.25" square frame and a stack length of 3 inches, dimensions that fit common NEMA 34 mounting footprints. Primary position feedback is provided by a frameless resolver, size 21, which supplies rotor angle data during rapid reversals and tolerates high ambient temperatures. The motor has no holding brake or shaft seal, and housing style C is assigned at the factory. It is supplied without secondary feedback, which reduces wiring complexity in applications that rely only on resolver position data.
