Product Description:
The R45GENA-HS-NS-NV-00 is a servo motor manufactured by Pacific Scientific for the R Servomotors series. It serves as a brushless rotary actuator that delivers commanded torque and speed to indexing tables, pick-and-place wrists, and compact gantry axes used in industrial automation. By combining a low-inertia rotor with high-energy magnets, the motor supports tight position loops and fast direction changes required by contemporary motion controllers.
The continuous stall torque is 5.7 Nm, allowing a drive to hold static loads without overheating the motor. During acceleration, the electromagnetic stack supplies a peak torque of 15.1 Nm for short overload periods. The stator and shaft sit inside a 4.25-inch square frame that fits common NEMA-style mounts. Responsiveness is enhanced by a rotor inertia of 0.31 kg·m² × 10⁻³, which helps keep settling times low in high-bandwidth control loops. Torque density is increased by rare earth samarium cobalt magnets that preserve magnetic flux at elevated temperatures. The housing follows the standard style, and the winding uses the standard option, so its thermal and electrical characteristics align with compatible drive ratings.
Feedback to the drive is supplied by Hall sensors, and no resolver or encoder is fitted for secondary feedback. The motor is supplied with no brake, so applications must rely on drive torque or external hardware for static holding. It also has no shaft seal, making it necessary to keep the output away from liquids and excessive dust. The laminated stack extends 5 inches along the axis, providing the active magnetic length needed for the motor’s torque output. The English-unit mounting interface provides an inch-based pilot and threaded holes for direct coupling to compatible gearboxes. Its standard housing arrangement maintains consistent heat transfer from the stator to the surrounding structure during operation.
