Product Description:

The R8AGENA-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific within the R Servomotors series. This rotary unit converts commanded electrical power into controlled mechanical motion for axes that require precise speed and torque regulation in automated machinery, material-handling stations, and process equipment. By integrating with a drive amplifier and motion controller, the motor forms the electromechanical actuator that positions loads according to the programmed motion profile of the overall system.

Its physical footprint is set by a 7.5 in square frame, which establishes the flange pattern and clearance in the machine layout. Under continuous duty, the motor can deliver 53.4 Nm of continuous stall torque without exceeding thermal limits. Rated speed is 1200 rpm, the rotational velocity achieved when the motor is supplied with nominal current and operates at rated temperature. For dynamic peaks such as acceleration or short overloads, the rotor can generate up to 109 Nm, giving extra drive margin before torque foldback occurs. The rotating mass presents an inertia of 10.8 × 10⁻³ kg·m², influencing the response to command changes and the tuning parameters of the drive regulator.

Magnetic energy is supplied by a rare earth (samarium cobalt) magnet set, allowing high torque density while maintaining thermal stability over extended cycles. The active iron path is extended through a 10 inch stack length, which increases the available flux linkage and supports the continuous rating. Position data is returned through a frameless resolver, transmitter type, size 21, supporting commutation and speed feedback for the drive. Installation follows an English mounting pattern, and the unit is factory-configured without a holding brake or a shaft seal, making it suitable for applications that already incorporate external mechanical locks or operate in clean, protected environments.
