Product Description:

Pacific Scientific builds the R46GENA-TS-NG-NV-00 within the R Servomotors series. This motor converts electrical drive commands into controlled rotary torque for pick-and-place arms, index tables, and compact conveyors across industrial automation cells. It is intended for motion systems that need repeatable positioning in a compact motor package. Its rare-earth magnet topology, feedback options, and square frame are sized for direct coupling to load shafts, eliminating mechanical slack and improving repeatability in closed-loop motion axes.

The motor supplies a continuous stall torque of 7.6 Nm, letting it support static loads without overheating, while a peak output of 20.2 Nm handles brief acceleration spikes during cycle changes. A rotor inertia of 0.40 kg·m² × 10⁻³ balances speed response and stability, enabling tight velocity loops when driven by modern amplifiers. This output profile suits indexing moves that demand quick bursts of torque followed by steady holding. The 4.25" square frame matches NEMA-type plates used with the English mounting pattern, and the standard housing style simplifies airflow around the motor. High-energy magnets made from samarium cobalt sustain torque density over a broad temperature range, and the standard winding option aligns with commonly available bus voltages and current ratings.

Axial stack length is 6 inches, keeping the motor compact enough for multi-axis carriages while still providing the required torque. For motion feedback, a Tachsyn resolver delivers analog speed and coarse position data, and a secondary 1024 ppr encoder supplies incremental digital information for high-resolution positioning. Using both feedback devices lets compatible controls combine analog feedback with higher-resolution incremental tracking. Because the assembly is shipped with no brake, holding force must be generated either by the drive or by an external clamp during power-off states. The absence of a shaft seal means the shaft opening is not protected against fluid ingress, so the motor should be mounted away from washdown areas.
