Product Description:

The R34KMNC-R2-NS-NV-00 is a servo motor built by Pacific Scientific within the R Servomotors series. As an electromechanical drive component, it converts controlled electrical input from a servo amplifier into controlled rotational motion that supports position, velocity, and torque loops in automated machinery. The motor is intended for integration into metric mechanical platforms where a compact form factor and high dynamic response are needed in pick-and-place gantries, indexing tables, or light conveyor axes.

Its performance envelope begins with a continuous stall torque of 3.2 Nm, allowing the axis to hold load at zero speed without overheating. Short bursts can deliver up to 8.30 Nm of peak torque for acceleration events. The rotor reaches a rated speed of 4000 rpm, providing a balance between velocity bandwidth and mechanical life. Dynamic response is aided by a rotor inertia of 0.11 kg·m² × 10⁻³, which helps minimize overshoot when paired with modern digital drives. All of this capacity fits inside a 3.25-inch square frame that matches NEMA-style mounting adapters common in smaller automation cells.

The motor uses rare earth (samarium cobalt) magnets, which resist demagnetization at elevated temperatures while enabling high flux density. The motor employs a frameless resolver, transmitter type, size 21 as the primary feedback device, so rotor angle is available to the drive controller. Stack iron is assembled to a 4 inch length, and the stator uses a medium-high winding to match typical 320 VDC bus voltages. A C-coded housing style provides centralized cabling access through the rear, and the body attaches with metric fasteners. Because there is no holding brake, no shaft seal, and no secondary feedback channel, installation is straightforward and back-driving friction is minimized.
