Product Description:

The R65GEAA-R2-NS-VS-00 is a servo motor produced by Pacific Scientific within the R Servomotors series. Designed for closed-loop positioning and velocity control, it delivers repeatable rotary motion to conveyors, gantries, and similar automated machinery on the plant floor. The motor is supplied as a complete electromechanical unit that mates with drives using a frameless resolver for primary feedback, allowing precise commutation without external encoders.

Its continuous stall torque is 13.6 Nm, giving the axis the ability to hold load at zero speed without overheating, while the peak torque rises to 33.3 Nm for brief acceleration or impact events. A rated output speed of 2000 rpm balances cycle time with mechanical wear in medium-throughput equipment. Dynamic response is helped by an inertial load of only 1.26 ×10⁻³ kg·m², so the drive can command rapid starts and stops with limited current. For vertical or safety-critical axes, a 24 V DC brake is integrated to lock the shaft when power is removed. The housing style is standard cast construction, and the windings follow the standard coil configuration used for this frame. Mounting follows the English bolt pattern, and there is no secondary feedback device.

Mechanically, the motor occupies a compact 5.75-inch square frame that fits existing machine layouts. Torque density is enhanced by magnets made from rare earth (samarium cobalt), which resist demagnetization at elevated temperatures. A Viton shaft seal guards the internal bearings against coolant or dust ingress when paired with proper cable glands. The laminated stack length measures 5 inches, providing the flux path necessary to meet the published torque values without extending overall width. The housing and stack share a standard finish that matches the rest of the R Servomotors line.
