Product Description:
The R46SENA-TS-MD-NV-02 belongs to the R Servomotors series manufactured by Pacific Scientific. This brushless unit is used in positioning tables, pick-and-place heads, and other industrial axes where repeatable speed and angular control are required. By combining a compact square frame with rare-earth magnet technology and resolver-type feedback, the motor converts electrical input from a drive into precise rotary motion that can be coordinated through a machine controller. Its feedback arrangement supports closed-loop control during frequent starts, stops, and low-speed positioning tasks. This makes the motor suitable for automation equipment that depends on consistent motion from cycle to cycle.
The motor can deliver a continuous stall torque of 7.6 Nm, so it can hold static loads without overheating when the shaft is not turning. For short acceleration bursts, it reaches a peak torque of 20.2 Nm, giving extra headroom for rapid indexing or brief shock loads. Rotor inertia is rated at 0.40 kg·m²×10⁻³, which supports quick speed changes while helping smooth small cyclical disturbances. The housing measures 4.25" square, which helps the motor fit into tight mechanical spaces, and the electromagnetic stack length of 6 inches adds copper volume so thermal limits are managed during continuous duty. The available torque reserve is useful on axes that must accelerate quickly or reverse direction in short intervals.
The mounting face follows the English bolt pattern, allowing direct installation on inch-based machine interfaces. The motor has a Standard housing style, meaning no external fins or special coatings are added. Internal magnets use Rare earth (samarium cobalt) material, which helps maintain magnetic strength at elevated temperatures and reduces demagnetization risk. Shaft position is provided by a Tachsyn transducer, so the drive receives tachometer and resolver signals from a single package. This arrangement reduces the need for separate external feedback hardware around the axis. The motor has no holding brake and no shaft seal, so load holding and environmental protection must be provided elsewhere in the machine.
