Product Description:

The F46GCNA-R2-NS-NV-00 is a brushless servo motor produced by Pacific Scientific within the F Servomotors series. Designed for closed-loop motion axes in packaging lines, pick-and-place gantries, and similar machinery, the unit converts electrical drive current into regulated rotary torque with positional accuracy. Its configuration matches common industrial interfaces, allowing it to pair with Pacific Scientific digital amplifiers and third-party controllers to actuate conveyors, lead screws, or belt stages as part of broader automation cells. Brushless operation lets the amplifier regulate current electronically for smooth acceleration, stable speed control, and repeatable directional changes during cyclic machine motion.

Its continuous stall capability is 61 lb-in, providing torque without overheating when the shaft is locked. For rapid indexing or shock loads, the motor delivers up to 155 lb-in of peak torque. The electromagnetic circuit produces this response with a torque constant of 11.0 lb-in/A, so drive current can be scaled directly from load demand. The motor has a voltage constant of 130 V/Krpm, so the drive must overcome the resulting back EMF as speed rises. The 4.25 inch frame width keeps the motor compatible with machine plates, while the IP65 enclosure shields internal windings from dust and low-pressure water jets. The laminated stator stack is six inches long, which increases surface area and supports heat dissipation at the stated torque levels.

The motor has a mass of 27.4 lbs, which adds thermal mass during intermittent overload duty. The front face uses the NEMA Face standard, so the motor mounts directly to gearheads or pump housings without adapters. Permanent magnets made from Ferrite provide the rotor field without electrical excitation. The motor has no holding brake or shaft seal, and position data comes only from the primary resolver for single-loop control schemes.
