Product Description:

The R46GEBA-R2-NS-NV-00 is a servo motor built by Pacific Scientific within the R Servomotors series. As a compact rotary actuator, it converts controlled electrical input into precise shaft motion for indexing tables, pick-and-place heads, and similar automated stations on the plant floor. By supplying commanded torque and velocity to a matched drive, the unit positions mechanical loads quickly while maintaining the closed-loop control needed in industrial automation. Its compact format also helps the motor fit machine axes where installation space is limited but accurate motion is still required.

A continuous stall capability of 7.6 Nm allows it to hold static loads without overheating, while a peak output of 20.2 Nm supports rapid acceleration during cycle changes. The combined rotor and shaft inertia is 0.40 kg·m² × 10⁻³, so control loops can be tuned for fast response without excessive overshoot. The housing measures 4.25" square, and the electromagnetic stack extends 6 inches, giving the motor a form factor that fits many mid-range gearheads and fixtures. This combination of torque, inertia, and package size supports responsive axis motion in compact machine assemblies.

For controlled stopping and hold-in-place requirements, the integrated 100 V dc brake clamps the shaft when power is removed. Torque production is sustained by rare earth (samarium cobalt) magnets that maintain field strength at elevated temperatures. Position feedback is provided by a frameless resolver of size 21, supplying analog sine-cosine signals to the controller, and no secondary feedback device is included. The design also includes no shaft seal, which suits clean environments where seal contact is unnecessary. This arrangement keeps the motor mechanically simple while supporting accurate feedback and reliable holding performance.
