Product Description:

The R46GEAA-R2-NS-NV-00 is an AC servo motor produced by Pacific Scientific and belongs to the R Servomotors series. Designed for closed-loop motion axes in packaging lines and material-handling gantries, the unit converts drive current into controlled rotary torque for positioning tasks. Its compact square frame and resolver feedback let the motor work with digital drives for repeatable speed and position regulation on automated machinery. It uses rare-earth magnets to increase torque density while keeping overall mass acceptable for moving axes. This makes the motor suitable for indexing tables, transfer axes, and other applications that require stable low-speed control and repeatable stopping points.

Its continuous stall torque of 7.6 Nm indicates the load the motor can hold indefinitely without overheating. A 4.25-inch square frame fits standard NEMA-equivalent mounts, while a rotor inertia of 0.40 kg·m² ×10⁻³ balances acceleration demands against load stability. Torque is generated with rare-earth samarium cobalt magnets, a material that maintains magnetic flux at elevated temperatures. A factory-fitted 24 V DC brake clamps the shaft when power is removed so vertical or overhung loads remain stationary. English mounting holes, a standard housing, and standard windings complete the mechanical interface.

Episodic load spikes are handled by a peak torque capacity of 20.2 Nm, giving the drive headroom for rapid indexing or sudden starts. The stack length measures 6 inches, so the motor extends minimally beyond gearboxes when space inside machines is limited. Position data is returned through a size 21 frameless resolver, providing analog sine-cosine signals that tolerate electrical noise better than optical encoders. There is no shaft seal, so the motor should be installed in environments free from liquid spray, and secondary feedback is omitted.
