Product Description:

The R65HENA-R2-NS-NV-00 belongs to Pacific Scientific's R Servomotors series and is a permanent-magnet AC servo motor. It operates with a compatible drive to provide closed-loop torque and speed control for conveyors, index tables, and gantry axes in automated equipment. The housing follows the standard format used across the R series, which helps keep the motor within a familiar mechanical envelope. The motor is intended for applications that need repeatable positioning and stable speed regulation under changing load conditions.

The motor delivers a continuous stall torque of 13.6 Nm, which means it can hold that output at zero speed within its thermal limits. For short acceleration demands, it can produce up to 33.3 Nm. It uses a high-speed winding, and the rotor can sustain 4300 rpm from the rated bus for applications that favor fast indexing over high holding force. Rotor inertia is 1.26 × 10⁻³ kg·m², which supports quick response while helping limit instability in belt-driven mechanics. This balance is useful on axes that must accelerate quickly without becoming difficult to tune. A frameless size-21 resolver provides the primary feedback signal for closed-loop control.

The mounting face measures 5.75-inch square, and the laminated stack extends 5 inches along the shaft axis to suit standard NEMA-style adapters. Torque is produced by rare-earth samarium cobalt magnets, which retain flux well through temperature changes seen in industrial equipment. The frame uses an English bolt pattern. The motor is supplied without a holding brake, without a shaft seal, and without secondary feedback. Its resolver leads exit through the standard housing, keeping the connection point in the usual location for this motor format. That layout supports straightforward cable routing in typical installations.
