Product Description:
The R45GENA-TS-NG-NV-00 is a servo motor manufactured by Pacific Scientific for the R Servomotors series. In automated machinery, the unit converts drive current into controlled rotary motion so axes can position loads with repeatable accuracy. Its design combines magnetic materials, feedback devices, and winding features selected for moderate-power positioning tasks in packaging lines, assembly stations, and similar industrial equipment. The motor can support applications that require accurate speed regulation and consistent positioning during repetitive operating cycles.
At the rotor, the continuous stall torque reaches 5.7 Nm, giving the axis sufficient holding force for sustained static loads, while a peak torque of 15.1 Nm handles brief acceleration demands. A rotor inertia of 0.31 ×10⁻³ kg·m² balances dynamic response with load stability, allowing precise control without excessive current surges. Torque is generated by rare-earth samarium-cobalt magnets, which provide high flux density in a compact enclosure. The 4.25-inch square frame fits equipment that follows NEMA-style flange patterns. The motor is supplied without a brake or shaft seal and uses the standard housing and winding configuration.
The motor has a stack length of 5 inches, providing the magnetic path needed to produce its rated torque while keeping the overall mass manageable. Its mechanical connection follows an English mounting layout, simplifying alignment with inch-based fixtures. Primary velocity feedback is supplied by a Tachsyn resolver, which provides the drive with rotor motion information for closed-loop control. Position data is supplemented by an incremental encoder that delivers 1024 ppr through differential signals to the drive. Because the motor does not have a shaft seal, the front bearing should be protected from fluid ingress when the unit operates near coolant, wash water, or other contaminants. Proper enclosure placement can also reduce exposure to airborne debris without changing the motor’s mounting arrangement.
