Product Description:

The R84GMNA-R2-NS-NV-00 is an AC permanent-magnet motor manufactured by Pacific Scientific within the R Servomotors series. Designed for closed-loop axis control on machine tools, material-handling equipment, and packaging stations, it converts drive current into precise rotational motion that can be commanded by a digital servo amplifier and continuously corrected by the servo loop. By delivering high torque from a compact package, the motor supports axes that must start, stop, reverse, and hold position repeatedly during automated production cycles where repeatable motion and stable low-speed control are required.

At stall, the rotor can deliver a continuous torque of 22.5 Nm, while short bursts can reach a peak of 44.5 Nm for rapid acceleration cycles and brief overload events. This output is produced within a frame that measures 7.5" square, allowing the motor to fit directly into compact metric gearboxes and bearing blocks where mounting space is limited. Rated speed is 3300 rpm, so the drive can maintain high surface velocity during fast transfer moves and other applications that need sustained rotary speed. System inertia is kept moderate at 4.43×10⁻³ kg·m², which helps the control loop respond quickly to commanded speed changes and short indexing moves while limiting sluggishness from rotor mass.

Magnetic flux is supplied by rare-earth samarium cobalt material, increasing torque density and thermal stability compared with older magnet systems. Position information is generated by a frameless resolver size 21, and there is no secondary feedback channel, which keeps the feedback arrangement straightforward and avoids extra signal wiring beyond the primary position device. The laminated core uses a stack length of 4 inches, and the housing follows the standard style with a metric mounting interface for direct installation on matching machine faces. The motor is supplied without a holding brake or shaft seal and uses standard windings, which reduce rotating drag and suit installations that do not require sealed shaft protection or power-off holding torque.
