Product Description:

The R32GENP-R2-NS-NV-00 servo motor is produced by Pacific Scientific as part of the R Servomotors series. This unit is built for closed-loop motion control where high torque density and explosion-proof construction are required in industrial automation equipment. It is suited for systems that need accurate speed and position control in sealed or hazardous locations. By converting electrical energy into controlled mechanical rotation, the motor positions machine axes, conveyors, or actuators in hazardous areas without sparking. Its design supports repeatable motion in automated handling and process equipment.

Its continuous stall torque of 1.7 Nm is the steady load it can hold without overheating, while a peak torque of 4.40 Nm allows short bursts for acceleration. A rated speed of 4000 rpm gives the shaft velocity attainable at nominal voltage and frequency, and rotor inertia of 0.071 kg·m² × 10⁻³ balances quick response with stability during rapid reversals. The explosion-proof housing encloses the windings and magnets so an internal fault will not ignite surrounding gases. The motor has no holding brake, which reduces overall size in classified zones. It also has no shaft seal, so installation requires an external barrier if fluid ingress is a concern, and the English mounting pattern matches common NEMA dimensions. Standard windings keep the electrical characteristics compatible with the manufacturer’s drives.

The motor uses a 3.25-inch square frame that fits compact gearboxes and couplings, and the rotor employs rare-earth samarium-cobalt magnets to sustain flux at elevated temperatures typical of hazardous-duty enclosures. Position data is delivered through a frameless size 21 resolver, which maintains reliable feedback in electrically noisy environments, and the design does not include a secondary feedback channel. This feedback arrangement helps the drive maintain stable rotor-angle tracking during speed changes and reversals. A 2-inch stack length helps limit axial mass so system inertia stays within normal drive tuning ranges.
