Product Description:

The Pacific Scientific R32GEN0-R2-NS-VS-00 belongs to the R Servomotors series and is classified as a motor intended for servo duty in industrial automation. Deployed with a matched drive, it converts electrical commands into tightly regulated rotary motion so that indexing tables, pick-and-place arms, or roll feeds can follow precise speed and torque profiles. By delivering closed-loop positioning without mechanical gearboxes, the unit minimizes backlash and supports repeatable process sequences on assembly lines and packaging equipment.

Its continuous stall capability of 1.7 Nm lets the shaft hold a load at zero speed without thermal overload, while a peak reserve of 4.40 Nm supplies extra torque during acceleration spikes. The motor has a rated speed of 4000 rpm, so it can support high-speed servo operation with a matching drive. Rotor inertia is limited to 0.071 kg·m² × 10⁻³, enabling rapid reversals with limited following error. The housing has a 3.25-inch square footprint, which eases installation where NEMA-sized motors were previously used. Torque is produced by rare-earth samarium cobalt magnets, which increase flux density without adding much mass. The winding uses a standard impedance pattern so conventional R-series drives can be used. Because the unit is supplied without a holding brake, load holding must be provided by the drive or an external latch. Secondary feedback devices are omitted, which reduces cable count and simplifies wiring.

Position data is returned by a frameless resolver in transmitter style and size 21, providing analog rotor-angle feedback to the drive. The motor body is sealed by a Viton shaft seal, which limits oil or coolant ingress where the shaft passes through a machine panel. A laminated core stack that is 2 inches long helps keep overall mass down and supports the stated stall capability. Mounting follows English bolt patterns, so the tapped holes align with inch-based frames and reduce the need for adapter plates.
