Product Description:

Pacific Scientific manufactures the R46GSNA-HS-SS-VS-01 in its R Servomotors series. The motor is built to deliver closed-loop torque and velocity in industrial automation, driving indexers, conveyors, and pick-and-place axes that demand repeatable positioning. By integrating into servo drive systems, it converts electrical commands into precise mechanical motion for the duty cycles common in packaging, electronic assembly, and material-handling lines. The compact square frame eases installation in existing mechanical layouts.

At the core of its performance is a continuous stall torque of 7.6 Nm, enabling the axis to hold load steadily without thermal drift. During acceleration or impact disturbances, the motor can reach a peak torque of 20.2 Nm, supplying the extra force needed for fast cycle transitions. Rotor inertia is limited to 0.40×10⁻³ kg·m², so velocity commands are executed with short settling times and minimal overshoot. The 4.25" square frame follows NEMA mounting conventions, making it suitable for machine layouts that use the same bolt pattern. The use of rare-earth samarium cobalt magnets increases flux density, letting the motor generate high torque from a relatively small envelope while maintaining thermal stability. The standard housing supports convection cooling.

Command resolution is handled by Hall sensors, which provide three-phase commutation signals to the drive and keep feedback wiring simple. A Viton shaft seal limits oil and dust ingress at the output journal, helping protect internal components during washdown or light splashing. The active iron stack is 6 inches long, a dimension that balances thermal mass with low rotor inertia while supporting strong torque output. Because the unit is supplied without a holding brake, external mechanical locking is required if power-off retention is needed. A standard winding configuration supports consistent electrical characteristics in applications that use matching voltage and current requirements.
