Product Description:

The R32GENP-R2-NS-VS-00 is a Pacific Scientific motor in the R Servomotors series that provides closed-loop rotary actuation for positioning tables, pick-and-place axes, and other automation tasks. It is delivered without a holding brake, relies on a standard winding set, and employs rare-earth samarium-cobalt magnets to sustain torque density while limiting demagnetization at elevated temperatures. That arrangement suits servo axes that rely on external holding force at standstill. English-pattern mounting gives the OEM flexibility to attach the housing directly to gearboxes or machine frames.

This model supplies a continuous stall torque of 1.7 Nm, enabling the shaft to resist steady external loads without motion. During acceleration or short overload events, it can deliver up to 4.40 Nm, providing headroom for dynamic indexing. The rated speed of 4000 rpm is the maximum continuous operating velocity when the motor is driven from a matched amplifier. A rotor inertia of 0.071 kg·m²×10⁻³ moderates speed changes so the control loop can reach target positions quickly without overshoot. The housing is classified as explosion-proof, allowing installation in hazardous areas that contain flammable gases or vapors. This enclosure helps contain ignition sources while preserving the motor's intended operating performance.

A 3.25-inch square frame fits into compact machinery and aligns with English bolt circles, streamlining mechanical interchange. Primary feedback is a frameless resolver (transmitter type, size 21) that supplies continuous position data for closed-loop control. The resolver format also avoids delicate optical components in the feedback path. A Viton shaft seal blocks dust and oil from entering the bearing cavity, complementing the explosion-proof enclosure. The active magnetic stack measures 2 inches long, balancing torque output against package length.
