Product Description:

The R46GENA-R2-NG-VS-00 is a servo motor manufactured by Pacific Scientific within the R Servomotors series. This brushless unit works with digital or analog drives to provide closed-loop rotary motion for pick-and-place systems, packaging axes, and printing equipment. Internal position feedback and a sealed housing help the motor maintain stable torque and speed during repetitive industrial duty. Its square-frame layout also suits English-dimension mounting patterns commonly used on North American machines. That format allows the motor to fit established mechanical layouts without requiring metric face conversions.

At rated current, the motor produces a continuous stall torque of 7.6 Nm, which supports load holding during static or very low-speed operation. For short acceleration bursts, it can reach a peak torque of 20.2 Nm when the application needs added momentary output. Rotor inertia is 0.40 kg·m² × 10⁻³, so drive tuning must account for the motor's response during speed changes. The housing uses a 4.25-inch square frame for straightforward installation on English-dimension brackets and gearheads. Magnetic flux is supplied by rare-earth samarium cobalt magnets, which improve torque density and help maintain thermal stability under demanding duty cycles.

Position feedback is provided by a frameless size 21 transmitter-type resolver, which delivers robust shaft-angle signals in electrically noisy environments. A secondary 1024 ppr line-driver encoder is also available for control systems that use incremental feedback channels. The output end is fitted with a Viton shaft seal to help block oil and dust in general-purpose plant atmospheres. The motor has a stack length of 6 inches and uses the standard resistance and inductance winding. It is supplied without a factory holding brake, so any holding function must come from the drive or from external machine hardware.
