Product Description:
The R63HENA-R2-NS-VS-00 is a Pacific Scientific servo motor built within the R Servomotors series. Intended for industrial automation, the unit converts drive current from a matched amplifier into mechanical rotation for high-speed positioning and process control. The standard housing relies on natural convection for cooling, which supports installation in systems that do not use forced airflow. This type of motor is used where rapid response and stable feedback are needed for repeated starts, stops, and speed changes on automated axes.
With a continuous stall torque of 8.3 Nm, the motor can hold loads in closed-loop operation without exceeding thermal limits. Its square frame measures 5.75 inches on each side, allowing installation in machines that follow NEMA-style size 63 envelopes. The rotor inertia is 0.81 × 10⁻³ kg·m², giving moderate acceleration capability for machines that use the English mounting pattern. A high-energy winding tuned for High Speed operation supports a rated mechanical velocity of 6000 rpm. The English mounting configuration aligns with front-face tapped holes used in North American automation layouts. The primary feedback device is a frameless size-21 resolver that provides continuous position data, and no secondary transducer is included.
Short-duration load peaks can be absorbed thanks to a peak torque of 20.5 Nm. The magnetic circuit uses rare-earth samarium cobalt segments, so demagnetization risk remains low during rapid cycles. A stack length of 3 inches balances the higher-energy magnets with axial space limits common in servo gantries. The front output shaft includes a Viton shaft seal, which provides chemical resistance against lubricants that may migrate along the mounting flange. That seal also helps protect the shaft area when the motor is mounted near lubricated couplings or gear interfaces. Because the model is supplied without a holding brake, external load-restraint hardware is required when the axis needs power-off retention.
