Product Description:
The R46GENH-R2-NS-NV-00 belongs to the R Servomotors series manufactured by Pacific Scientific. This product is a servo motor intended for industrial automation where accurate torque delivery and position control are required. It serves as the primary rotary actuator in systems that coordinate index tables, linear stages, or conveyor zones, responding to motion commands from a matched drive and converting electrical input into controlled rotary motion.
The motor can deliver a continuous stall torque of 7.6 Nm, which is the load it can sustain indefinitely at rated dissipation. For rapid acceleration or short load spikes, it supports a peak output of 20.2 Nm, providing headroom for dynamic cycles. Rotor inertia is specified at 0.40 kg·m² × 10⁻³, a comparatively low value that promotes quick speed changes while limiting control-loop effort. Its magnetic circuit uses rare-earth samarium cobalt material, which improves torque density and thermal stability compared with ferrite designs. Shaft position is reported through a frameless resolver, transmitter type, size 21, providing analog sine-cosine signals that remain functional in electrically noisy environments and across extended temperature ranges.
The housing fits a frame that measures 4.25" square, allowing direct interchange with legacy NEMA-frame gearboxes and mounts. The motor has an active stack length of 6 inches, which affects continuous power without enlarging the footprint. The motor has no shaft seal, so the installation should remain in clean environments or use external sealing if splash exposure is expected. Mechanical attachment uses the English mounting pattern, which simplifies alignment in machinery built around inch-based hardware. The motor ships without a holding brake and carries no secondary feedback device. It uses a standard winding that balances current demand with commonly available servo drives.
