Product Description:

The R22GENA-R1-NS-NV-01 is a brushless servo motor manufactured by Pacific Scientific within the R Servomotors series. It is intended for closed-loop motion systems where commanded current is converted into accurate rotary displacement. By combining compact construction with high-energy magnetic materials, the unit supports positioning tables, pick-and-place heads, and other cyclic machinery in industrial automation lines. Its round frame mates with modular gearheads, and it interfaces directly with the manufacturer’s digital drives through resolver feedback.

At the core of the motor’s capability is its continuous stall torque of 0.6 Nm, the steady twisting force it can sustain thermally. For short bursts it produces 1.62 Nm, giving machinery headroom for acceleration and shock loads. A rated velocity of 5300 rpm marks the operating ceiling under nominal bus voltage, supporting high cycle rates. Responsiveness is helped by a rotor inertia of 0.014 × 10⁻³ kg·m², so speed changes occur with limited overshoot. Flux is generated by rare earth (samarium cobalt) magnets; this material boosts torque density while resisting demagnetization at elevated temperatures. The motor is supplied without a brake, which shortens overall length, and the standard winding matches the drive’s default current tables.

The motor occupies a 2.0-inch OD cylindrical housing and carries a stack that is 2 inches long, permitting installation in space-limited enclosures. English-pattern threads simplify alignment with NEMA adapters, and the standard housing style supports straightforward mounting. The shaft exits with no shaft seal, a choice that minimizes friction but requires the coupling area to be protected from fluids. Position feedback is delivered by a frameless resolver transmitter, size 15; no secondary transducer is fitted, which reduces wiring complexity while still enabling high-resolution closed-loop control.
