Product Description:

The R45FCNA-TS-NS-VS-00 belongs to the R Servomotors series produced by Pacific Scientific. It is an AC servo motor intended to deliver closed-loop motion in positioning tables, pick-and-place heads, and other automation axes that require repeatable speed and torque control. By combining rare-earth magnet technology with feedback devices, this motor converts drive current into mechanical work while allowing the control system to regulate velocity and position under varying loads. That arrangement supports smooth acceleration and accurate stopping during repetitive machine cycles.

The motor develops a continuous stall torque of 5.7 Nm, giving the drive enough steady holding force for low-speed tasks. During rapid accelerations, it can reach a peak torque of 15.1 Nm, providing short-term overload capability for indexing moves. Rotor inertia is held to 0.31 kg·m² × 10⁻³, and this low value assists the controller in achieving fast dynamic response. Torque is generated by rare-earth magnets made of samarium cobalt, a material that maintains magnetic strength at elevated temperatures. The front face follows the NEMA Face pattern so it mounts directly to standardized gearheads and machine frames. Ingress protection at the shaft is supported by a Viton shaft seal, and the unit is shipped without a holding brake so external locking or drive torque must secure the load when power is removed.

Mechanical integration is simplified by the 4.25" Square frame and a stack length of 5 inches, dimensions that align with several planetary reducers used in material-handling equipment. Primary position and velocity data are delivered through a Tachsyn resolver; no secondary transducer is fitted, so the control loop relies exclusively on this signal. This arrangement keeps the feedback path simple and reduces the number of devices mounted on the motor body. The standard housing style supports fanless convection cooling, which helps the motor fit enclosed machine spaces without extra airflow hardware.
