Product Description:
Pacific Scientific produces the R65GENA-NP-RW-VS-00 servo motor within its R Servomotors series. The unit converts electrical energy into controlled mechanical rotation so automated axes can follow commanded profiles in packaging, material handling, or assembly equipment. Because it is a brushless servo device, it offers rapid torque response and precise positioning when combined with a compatible drive. Within a closed-loop drive system, it supplies the actuator side of the motion chain, letting controllers adjust speed and torque in real time.
The motor has a continuous stall torque of 13.6 Nm, which is the steady load it can hold indefinitely without exceeding thermal limits. During acceleration or transient events, it can deliver up to 33.3 Nm, providing reserve torque for overcoming inertia and friction. At its rated mechanical speed of 2000 rpm, the winding and magnetic design balance velocity with torque density for general-purpose servo axes. Rotor inertia is 1.26 kg·m² × 10⁻³, a moderate value that supports quick response without causing difficult tuning. The laminated steel frame measures 5.75 inches square, matching size-5 enclosures commonly used in standardized machinery.
The R65 frame is supplied in a standard housing and winding. A Viton shaft seal protects the internal bearing set from coolant or oil splash, while the stator stack length of 5 inches establishes the active copper volume that generates torque. Magnetic flux is produced by rare earth samarium cobalt material, giving high energy density without enlarging the motor. The motor is supplied without a factory-installed brake, and there is no primary feedback device, allowing an external encoder to be added if needed. Installation follows the English mounting pattern, keeping hole spacing consistent with legacy Pacific Scientific servomotor footprints.
