Product Description:
The R33GENA-HS-LB-NV-00 is a brushless rotary actuator manufactured by Pacific Scientific for the R Servomotors series. It is intended for closed-loop motion control in automated machinery. The motor supplies programmable speed and torque for indexing, clamping, and conveying operations while helping the drive maintain a low following error. Its rotary design allows it to operate as a controlled axis in packaging equipment, assembly systems, material-handling machinery, and other applications that require accurate movement.
The motor develops a continuous stall torque of 2.5 Nm, allowing it to hold static machine loads without overheating under suitable operating conditions. Its peak torque of 6.54 Nm accommodates brief acceleration demands and impact events. A compact 3.25-inch square frame allows the motor to fit within tightly spaced multi-axis arrangements. The rotor has a reflected inertia of 0.093 kg·m² × 10⁻³, which limits stored kinetic energy and supports responsive speed and position changes. At its rated operating point, the shaft turns at 3000 rpm for use in midrange industrial motion systems. English face mounting provides the mechanical attachment interface, while the three-inch laminated stack supplies sufficient space for the standard winding.
Primary commutation feedback is provided by Hall sensors, which report rotor position to the compatible servo drive. Fine position feedback is supplied by an encoder with 1000 ppr and a differential line driver that helps preserve signal quality in electrically noisy machinery. The magnetic field is produced by a rare-earth samarium-cobalt magnet ring, providing greater torque density than a comparable ferrite design. The housing uses the standard form factor for this motor configuration. The motor is supplied without a holding brake, so stationary load retention must be provided by drive torque or an external mechanism when required. It also has no shaft seal and is therefore suited to guarded, clean environments where the shaft interface is not exposed to liquids or heavy contamination.
