Product Description:

The R34JENP-R2-NS-NV-00 is a brushless AC servo motor produced by Pacific Scientific within the R Servomotors series. As a positioning element, it supplies programmable speed and torque for automated conveyors, material-handling axes, and small machining spindles. The unit combines a sealed stainless-steel conduit box with an enclosure intended for hazardous industrial zones where ignitable gases may be present. This arrangement allows the motor to be installed on process equipment that operates around volatile atmospheres while still providing controlled motion.

The motor delivers a rated shaft speed of 2300 rpm. At zero speed, it can hold a continuous stall torque of 3.2 Nm, while momentary load surges are handled up to a peak of 8.30 Nm. Dynamic response is aided by a rotor inertia of 0.11 kg·m² × 10⁻³, which lets the drive accelerate or decelerate quickly without excessive control effort. An explosion-proof housing helps prevent arc propagation to the surrounding atmosphere. The motor is supplied without a holding brake, so external mechanical retention must be used when power is off, and the medium-density stator winding supports balanced thermal loading.

The frame has a square cross-section of 3.25 inches square, and the active magnetic stack extends 4 inches along the shaft axis to keep overall length short. High-energy rare-earth samarium cobalt magnets sustain torque at elevated temperatures and improve demagnetization resistance over ceramic designs. Motion feedback is furnished by a frameless size 21 resolver, which provides reliable commutation and closed-loop control in electrically noisy environments. English-pattern face mounting supports direct attachment to compatible machine faces, and the motor is built without a shaft seal. No secondary feedback channel is provided, which helps keep cable routing straightforward.
