Product Description:
The R34JENT-TS-LB-NV-01 is a servo motor produced by Pacific Scientific within the R Servomotors series. Intended for commanded motion axes, it converts electrical power from a matched drive into regulated rotary output that precisely positions fixtures, actuators, and machine tools. By combining a compact frame with high-energy permanent magnets and closed-loop feedback, the device delivers a high dynamic range while keeping thermal loads manageable. It is used in automated assembly, packaging, and material-handling systems.
At stall, the motor develops 3.2 Nm of continuous torque, allowing the axis to sustain static loads without overheating. During rapid indexing, it can reach a peak of 8.30 Nm, providing extra force for acceleration profiles. A rated speed of 2300 rpm aligns with mid-range drives and supports stable velocity regulation. Servo loop responsiveness benefits from the rotor inertia of only 0.11 kg·m² × 10⁻³, reducing settling times after direction changes. Output power is created by a set of samarium cobalt rare-earth magnets, whose high flux density works with the medium winding to balance current demand and the voltage constant. The English mounting face simplifies mechanical integration with standard NEMA equipment.
Physically, the motor occupies a 3.25-inch square frame with a stack length of 4 inches, allowing multiple axes to fit into tight spaces. The primary feedback device is a Tachsyn, which supplies combined resolver and tachometer signals for velocity loops, while a secondary 1000 ppr line-driver encoder delivers incremental digital counts for fine position control. The model ships without a brake, so an external holding mechanism is required when power-off retention is needed, and it also has no shaft seal, making it suitable only for clean or protected environments.
