Product Description:

Pacific Scientific manufactures the R46GENA-T2-NS-NV-02 in the R Servomotors series. Classified as a servo motor, it is designed for industrial automation loops that demand precise torque and velocity control, such as indexing tables, pick-and-place gantries, and coordinated multi-axis cells. When paired with a compatible drive, the unit delivers commanded motion profiles while feeding position data back to the controller, allowing tightly synchronized machine cycles with minimal mechanical backlash. This makes it suitable for applications that rely on repeatable starts, stops, and direction changes under closed-loop control.

At a standstill, the motor can exert a continuous torque of 7.6 Nm, so thermal limits are not exceeded during static holding duties. For rapid indexing moves, it produces up to 20.2 Nm of peak torque, giving margin for overcoming reflected load inertia. The rotor’s moment of inertia is 0.40×10⁻³ kg·m², which supports quick acceleration without demanding excessive drive current. A square footprint of 4.25 inches on each side aligns with common gearhead adapters, and the electromagnetic stack length measures 6 inches to balance torque and overall size. The housing style and winding are standard, which keeps the configuration straightforward within the series. The compact format also helps the motor fit into machines where available mounting space is limited.

The rotor employs rare earth samarium cobalt magnets that retain flux at elevated temperatures and contribute to high torque density. All mounting holes follow an English pattern, so inch-based hardware can be used without metric conversion. Because the motor is supplied with no brake, vertical loads must be secured by other means, and the choice eliminates extra inertia in high-speed axes. The front end has no shaft seal, so the motor is better suited to clean, enclosed installations where fluids are not present at the shaft. There is no secondary feedback device, resulting in a lighter assembly with fewer service items. The absence of extra feedback hardware also reduces rear-end complexity and leaves more room for cable routing around the motor.
