Product Description:
The R8AGENA-R2-NG-NV-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. As a rotary actuator, it converts drive current into controlled mechanical motion for positioning tables, presses, and similar industrial automation axes. The motor belongs to the manufacturer’s medium-torque class and provides closed-loop performance when paired with a compatible feedback device and motion control drive.
The motor produces a continuous stall torque of 53.4 Nm, allowing the shaft to hold static loads without overheating. Its peak torque rating of 109 Nm supports short acceleration periods and sudden load changes. A rotor inertia of 10.8 kg·m² × 10⁻³ supports rapid speed changes while helping the motor maintain stable operation at low speeds. The square frame measures 7.5 inches per side and fits compatible NEMA-style brackets. Base mounting uses an inch-based bolt pattern for accurate alignment with the driven equipment. The rated operating speed is 1200 rpm, which supports continuous-duty operation within the motor’s thermal limits. A samarium-cobalt rare-earth magnet set provides high magnetic energy density and resistance to demagnetization, while the standard winding balances current demand with the available voltage range.
Position feedback reaches the drive through a size 21 frameless resolver, which provides durable rotor-position sensing for closed-loop control. A secondary encoder delivers 1024 ppr differential signals for controllers that require incremental position data. The laminated stack is 10 inches long, providing the magnetic path needed to support the motor’s torque output without unnecessary mass. The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must secure stationary loads when required. It also has no shaft seal, so the installation must provide suitable protection against contaminants and moisture. The standard housing style supports installation with compatible mounting hardware and cable arrangements across the R Servomotors series.
