Product Description:

The F43GENA-R2-NS-NG-00 is a brushless servo motor produced by Pacific Scientific within the F Servomotors series. It serves as the rotary actuator in indexing tables, pick-and-place heads, and other motion modules that require precise speed regulation and repeatable torque. By combining permanent-magnet excitation with electronic commutation, the unit delivers accurate positioning while eliminating the maintenance associated with brushed designs. Its operating style suits automated axes that need steady response during frequent starts, stops, and direction changes.

It delivers a continuous stall torque of 32 lb-in, allowing the shaft to resist static loads without thermal rise under rated cooling. For fast transient moves, peak torque climbs to 81 lb-in, giving the axis additional headroom for acceleration or shock absorption. The electromagnetic circuit produces a torque constant of 10.8 lb-in/A, so drive current can be estimated directly from commanded torque. This lets the drive relate commanded current to produced torque with straightforward scaling. Back EMF develops in proportion to speed at 128 V/Krpm, so a 3,000 rpm operating point requires roughly 384 V. A frame width of 4.25 inches fixes the mounting footprint. The motor uses magnet stack length code 3 to provide the active axial length that supports these torque values. It has no secondary feedback, so only the primary feedback channel is present. Its shaft and flange use the English mounting standard.

The housing carries a protection rating of IP65, sealing the windings against dust ingress and low-pressure water jets encountered on factory floors. This helps protect internal components in areas where dust and light washdown spray may be present. Permanent magnets made from Ferrite stabilize the magnetic field across moderate temperature shifts. The assembly weighs 16.6 lbs, which helps limit the added load on moving carriages or robotic arms. Because the unit is supplied with no brake, external holding devices are required when power-off position retention is critical. The configuration code is standard.
