Product Description:

The F43GCNA-R2-NS-VS-00 is a brushless servo motor manufactured by Pacific Scientific and offered as part of the F Servomotors series. The unit is intended to provide closed-loop rotary actuation for positioning tables, pick-and-place heads, and other motion axes in industrial automation. By converting electrical drive current into controlled torque output, it allows a controller to move loads with repeatable speed and position accuracy that are essential for manufacturing cells and material-handling equipment.

At stall, the motor delivers a continuous torque of 32 lb-in, allowing it to hold loads steadily without overheating, and it can reach a peak torque of 81 lb-in during acceleration for rapid indexing. Each ampere of phase current produces 10.8 lb-in./A, and the induced back EMF rises at 128 V/Krpm. With a frame width of 4.25 inches, the motor fits equipment designed around NEMA 42 face dimensions, and the NEMA face mounting pattern supports use in machines with the same footprint. The housing carries an IP65 rating, so it resists dust ingress and tolerates low-pressure washdown in packaging or food processing lines.

The motor weighs 16.6 lbs, which helps with sizing for gantry carriages or robot wrists without requiring excessive counterbalance. Shaft sealing is handled by a Viton shaft seal, which resists common industrial lubricants and helps maintain the enclosure rating. The rotor uses Ferrite magnets arranged in stack length 3 to provide the required magnetic flux characteristics. Because the design is a standard configuration and is supplied without a brake, external holding methods are required if power-off retention is necessary. The absence of secondary feedback means position data are provided only by the drive’s primary resolver or encoder, which simplifies the cabling set while still supporting normal servo loop requirements.
