Product Description:

The R84GENA-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific and supplied within the R Servomotors series. As a rotary actuator for industrial automation, it converts drive current from a compatible amplifier into precise mechanical motion for indexing tables, packaging axes, and material-handling gantries. The motor is intended for applications that require closed-loop velocity and position control. It is suited to axes that need repeatable starts, stops, and directional changes during normal operation.

At stall, the rotor delivers continuous torque of 22.5 Nm, allowing it to hold load at zero speed without overheating during continuous duty. The motor uses a 7.5-inch square frame that fits inch-based machine layouts common in U.S. equipment. Rotor inertia is rated at 4.43 kgm² × 10⁻³, which supports a balance between acceleration response and stable speed control. High-energy rare-earth samarium cobalt magnets provide strong magnetic flux and resist demagnetization at elevated temperatures. The motor uses an English bolt pattern for mounting, and it is supplied without a holding brake, without a shaft seal, and with a standard housing style.

For short bursts, the unit can reach 44.5 Nm of peak torque before returning to its continuous operating range. Its rated speed is 3300 rpm, and the magnetic stack length is 4 inches, which contributes to the active coil volume and heat dissipation under sustained load. Position feedback is handled by a frameless resolver in transmitter type, size 21, and no secondary feedback device is installed. Because the winding uses the standard configuration, integration with compatible Pacific Scientific drives is straightforward, and resolver feedback also offers good resistance to vibration and electrical noise in industrial service.
