Product Description:

The R45HCNA-TS-NF-NV-00 servo motor is manufactured by Pacific Scientific as part of the R Servomotors series. This brushless unit serves as a compact torque source in automated machinery, providing position and speed control for pick-and-place heads, feeders, and other precision axes. By combining feedback devices with compatible drive electronics, the motor supports repeatable motion profiles that help maintain throughput and accuracy in modern production equipment. It is suited for compact motion systems that need controlled acceleration and consistent speed regulation.

At a continuous stall torque of 5.7 Nm, the motor can hold or drive a load without overheating when ventilation is limited. Its square frame measures 4.25 inches on each side, which helps it match common NEMA-size actuator footprints and align with standard gearbox mounting patterns. Rotor inertia of 0.31 kg·m² × 10⁻³ supports a balance between quick acceleration and stable settling, while installation is provided through a NEMA face flange for direct coupling. A high-speed winding allows higher electrical frequency for rated power at elevated rpm while helping limit copper loss, and the motor uses a standard housing without a built-in brake. Primary feedback is provided by a Tachsyn resolver, and no shaft seal is fitted, so the front bearing area should be kept away from liquid spray.

For rapid indexing, the electromagnetic circuit can momentarily deliver up to 15.1 Nm, allowing the axis to overcome startup friction before returning to its continuous limit. This performance is supported by rare-earth samarium cobalt magnets, which maintain flux density over a wide thermal range and help preserve servo bandwidth during extended duty cycles. The laminated stack is 5 inches long, adding copper length and thermal mass without increasing the frame size. Position feedback is also available from a 1000 ppr line-driver encoder, which sends differential signals to digital drives used in electrically noisy cabinets.
