Product Description:

The R34JENC-R2-NG-NV-00 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. It is intended for use inside industrial automation cells where coordinated motion is required; when coupled to a matched drive, the unit delivers commandable shaft rotation for pick-and-place modules, web tension systems, and indexing tables. By integrating resolver and encoder feedback in a single housing, the motor enables high-integrity position loops without requiring external transducers.

It produces a continuous stall torque of 3.2 Nm, allowing the axis to maintain load at zero speed without overheating. During acceleration or brief overloads, the electromagnetic design can reach a peak output of 8.30 Nm, providing headroom for dynamic moves. A rated mechanical speed of 2300 rpm aligns the motor with medium-frequency servo drives commonly found on packaging and material-handling equipment. Rotor inertia is held to 0.11×10⁻³ kg·m², so velocity changes occur quickly without excessive following error. All of these elements are packaged inside a compact 3.25-inch square frame that simplifies mounting in tight machine spaces. The medium-class winding selected for this model balances copper loss and current demand during continuous operation.

Performance is supported by rare-earth samarium cobalt magnets that increase torque density while resisting demagnetization at elevated temperatures. Position feedback for the control loop comes from a frameless resolver and, for higher resolution, from a 1024 ppr line-driver encoder installed as secondary feedback. The motor is supplied with no holding brake, so any static locking must be provided by the machine mechanics, and it has no shaft seal to reduce drag in clean environments. Mounting follows the English bolt pattern, housing style C offers a standard flange geometry, and the 4-inch stack length provides the torque-to-length ratio needed for multi-axis gantries without increasing mass.
