Product Description:

The F43GCNA-R2-NS-NV-00 belongs to the F Servomotors series produced by Pacific Scientific. It is a brushless motor intended for closed-loop motion axes on pick-and-place heads, index tables, and similar industrial automation tasks that demand precise velocity and position regulation. A standard mechanical layout and the absence of an integral brake keep the motor compatible with drive stages that rely on external holding methods when power is removed. That arrangement suits machine designs that handle load retention outside the motor housing. Its form factor is well suited to compact axes where accurate motion matters more than built-in braking hardware.

This model can deliver a continuous stall load of 32 lb-in and can reach a transient capability of 81 lb-in during acceleration or brief overloads. Each ampere applied to the windings produces 10.8 lb-in/A, while the back EMF rises at 128 V/Krpm, which helps when matching the motor to a suitable drive. The frame measures 4.25 inches across the mounting face, and the housing bolts directly to gearboxes or machine plates through a NEMA face mounting pattern. A three-layer magnet stack supplies flux, and the motor uses length code 3 for the active axial section that produces torque. The motor ships in a standard configuration, lacks secondary feedback devices, and has no shaft seal on the output journal, which keeps the assembly straightforward.

The internal magnet set uses Ferrite material, and the housing has an IP65 rating that blocks dust ingress and low-pressure water jets. Overall mass is 16.6 lbs, which helps moderate temperature rise during extended duty cycles. The face sealing system and protected enclosure allow installation near coolant spray zones when the shaft path is kept out of direct fluid flow. Its weight also helps the housing resist rapid thermal swings during long operating periods.
