Product Description:

The R45GCNA-TS-NS-NV-00 servo motor belongs to the R Servomotors series manufactured by Pacific Scientific. This model is used in industrial automation to translate drive commands into precise rotary motion for conveyors, indexing tables, and packaging axes. As a member of the series, it combines a standard housing with a frame that integrates directly with motion controllers, giving machine builders a ready-to-install actuator.

The drive section is rated for a continuous stall torque of 5.7 Nm, giving it the ability to hold loads without thermal drift during closed-loop positioning. During acceleration events, the electromagnetic structure can reach a peak torque of 15.1 Nm, supplying short bursts of force for rapid indexing. A square frame that measures 4.25 inches on each side sets the mounting envelope, while a NEMA Face flange aligns the pilot with standard gearboxes and reducers. Rotor mass distribution is characterized by an inertia of 0.31 kg·m² × 10⁻³, and this low value lets the axis change speed quickly with modest current demand. These values indicate the motor's mechanical load limits and its responsiveness in a servo loop.

A rare-earth magnetic circuit built with samarium cobalt improves torque density while preserving thermal stability across the motor stack. The laminated core is wound with the series' standard copper configuration, and a standard housing style leaves external dimensions unchanged across windings. Rotor position data is supplied by a Tachsyn resolver, and no secondary encoder is installed, simplifying cabling when only velocity feedback is required. Because the stack measures 5 inches deep, the motor fits shallow enclosures often found on compact machinery. The unit is delivered without a holding brake and with no shaft seal, so external means are required for static load retention and for sealing when liquids or dust are present.
