Product Description:

The R22GMNA-R1-NS-NV-01 is a brushless servo motor manufactured by Pacific Scientific for the R Servomotors series. It transforms commanded current into controlled shaft rotation so that automation controllers can position loads accurately and maintain programmed velocities. With a compact housing and resolver feedback, it suits indexing tables, small pick-and-place arms, and packaging axes that require consistent motion under closed-loop control.

The motor produces a continuous stall torque of 0.6 Nm, allowing it to hold loads at zero speed without exceeding its thermal rating. For quicker starts and stops, peak output rises to 1.62 Nm, giving short-term headroom for accelerating higher-inertia mechanisms. Nominal operating speed is 5300 rpm, which balances torque density with manageable back EMF for the drive electronics. The rotor’s reflected inertia is only 0.014 kg m² × 10⁻³, a low figure that improves dynamic response while helping the servo system remain responsive in precision applications. Flux is generated by rare-earth samarium cobalt magnets, which provide high magnetic strength and stable properties over a wide temperature range.

Installation requirements are modest because the frame has a 2.0-inch outside diameter and an active stack length of 2 inches, allowing the motor to fit in tight spaces where axial room is limited. A metric mounting pattern simplifies attachment to international machine frames, while the shaft is supplied without a seal to minimize friction in low-pressure environments. Position feedback is supplied through a frameless resolver, transmitter type, size 15, providing sine-cosine signals that many industrial drives can process without an additional encoder. The unit is shipped without a holding brake, so power-off retention must rely on drive torque or an external locking device.
