Product Description:

The R46GEBA-R2-NS-VS-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. In industrial automation, this product couples to a drive controller and converts commanded current into proportional shaft rotation, giving machines the precise position and speed control required for indexing tables, packaging axes, or web-handling equipment. The housing is the standard style used across the series, so cable glands and conduit hardware line up with existing installations.

The motor supplies a continuous stall torque of 7.6 Nm, so it can hold or slowly move a load without overheating when ventilation is limited. During rapid starts, the drive may draw on up to 20.2 Nm of peak torque for short bursts that overcome static friction. Rotor inertia is only 0.40 × 10⁻³ kg·m², allowing the control loop to change speed quickly while keeping overshoot minimal. A square frame that measures 4.25″ on each side fits common machine plates, and the English mounting pattern avoids adapter brackets. For static holding, the integrated 100 V dc brake clamps the shaft when supply power is removed, protecting vertical or safety-critical axes.

A Viton shaft seal keeps lubricant inside the bearings and blocks dust or coolant from entering the enclosure. Torque density is boosted by magnets made of rare earth (samarium cobalt), which maintain their flux at elevated temperatures and extend service life. Stack length measures 6 inches, a dimension that influences the effective copper volume and the winding resistance used for the standard coil set. Primary feedback comes from a frameless resolver, transmitter type, size 21. This analog device provides absolute position over one electrical revolution and tolerates high vibration better than optical encoders. The design uses English fasteners, has no secondary feedback channel, and employs the standard winding scheme for compatibility with the manufacturer’s matched servo drives.
