Product Description:

Pacific Scientific manufactures the R34JMNC-R2-NS-NV-00 as part of its R Servomotors series. The unit is a brushless servo motor that supplies closed-loop mechanical power to indexing tables, pick-and-place axes, and packaging actuators across automated lines. By converting electrical energy into controlled torque and speed, it supports precise positioning where fast response and repeatable accuracy are required in industrial automation. Its brushless construction also avoids brush wear, which helps maintain stable operation in continuous-duty motion systems.

At stall, the motor delivers 3.2 Nm of continuous torque, providing holding capability for loads that remain engaged for long periods. When acceleration demands rise, it can reach 8.30 Nm of peak torque for brief intervals, supplying extra torque for rapid starts. The rated shaft speed of 2300 rpm balances throughput with thermal limits and suits many medium-inertia axes. Rotor inertia is 0.11 kg·m² × 10⁻³, so command changes translate into quick yet stable motion without excessive overshoot. A compact 3.25-inch square frame eases integration in crowded equipment, while the C housing style uses a straight cylindrical body that fits standard clamp mounts. Metric mounting holes support installation on machinery built to metric hardware standards. The design does not include a holding brake or a shaft seal, so external holding methods and clean, dry mounting locations are necessary.

Torque density is aided by samarium cobalt rare-earth magnets that sustain magnetic flux at elevated temperatures. Primary feedback comes from a frameless resolver in size 21 format, providing rotor angle feedback for analog or digital drives. The laminated stack is 4 inches long, giving the magnetic core enough length to achieve the stated torque while keeping the overall package manageable. The motor uses a medium winding, which offers a practical balance between current demand and thermal rise for general-purpose servo amplifiers. There is no secondary feedback channel, so the drive relies on the resolver alone for motion feedback.
