Product Description:

The R34JEBC-R2-NS-NV-00 is a Pacific Scientific servo motor from the R Servomotors series. It is intended for closed-loop industrial axes where accurate velocity and position control are essential, such as palletizers, gantry drives, or indexing tables. By combining an electromagnetic stator winding with permanent magnets on the rotor, it produces controllable torque that can be modulated by a matched digital drive.

The motor fits into machines with a compact 3.25-inch square frame, allowing installation in space-restricted mounts that follow NEMA-style dimensions. Its continuous stall capability is rated at 3.2 Nm, while the peak limit reaches 8.30 Nm; these values show the allowable load range for steady holding and short acceleration bursts. A rotor inertia of 0.11 × 10⁻³ kg·m² supports tight loop gains without excessive overshoot, so the drive can command rapid speed changes with minimal settling time. When driven at its rated electrical frequency, the shaft reaches 2300 rpm, which suits medium-throughput packaging or conveying equipment.

For applications that must hold position after power is removed, a 100 V DC brake is integrated at the non-drive end and can be wired to an independent safety supply. Primary motion feedback is delivered by a frameless size 21 resolver, and this analog sensor provides shaft angle information for commutation over each revolution without requiring batteries. Magnetic excitation is produced by rare-earth samarium cobalt material, giving high torque density and stable flux across a wide temperature range. The electromagnetic stack length measures 4 inches, which corresponds to the C housing style and a medium winding option that balances current demand with thermal rise. The motor also uses English mounting threads, has no shaft seal, and includes no secondary feedback channel.
