Product Description:

The F46HEAA-R2-NS-NV-00 is a brushless servo motor manufactured by Pacific Scientific within the F Servomotors series. It provides closed-loop rotary motion for automated equipment that requires accurate velocity and torque regulation. An English mounting pattern lets the unit bolt directly to inch-dimension gearboxes. The design also supports drive systems that work without secondary feedback, which helps simplify wiring in packaging machines, pick-and-place robots, and indexing tables. This arrangement is useful in compact motion systems where available installation space and cable routing paths are limited.

Rated continuous stall capability is 61 lb-in, allowing the shaft to resist that load indefinitely under natural convection. The square housing measures 4.25 inches across, matching common NEMA 42 flanges while keeping inertia moderate. For short accelerations, the motor can reach 155 lb-in of peak torque. The torque constant is 5.5 lb-in/A, so each ampere commanded by the drive produces that amount of torque. A back-EMF slope of 65 V/Krpm guides DC bus selection because the motor returns 65 volts for every 1000 rpm. These operating values are supported by a six-layer magnet stack and the standard winding arrangement, which helps balance copper fill, thermal dissipation, and motor response during repeated motion cycles.

An integrated 24-volt brake draws 0.22 A and secures the shaft with 72 lb-in of static holding torque during power-off states. The enclosure carries an IP65 rating, shielding internal parts from dust and low-pressure water jets, though no shaft seal is fitted, so direct fluid exposure at the coupling end should be avoided. Total mass is 27.4 lbs, which adds stability without making the motor unusually heavy for its frame size. Rotor poles use Ferrite magnets arranged in a length-6 stack, supporting reliable field strength for the published torque and speed behavior. This combination of brake, enclosure protection, and magnetic design makes the motor suitable for general industrial motion axes that require controlled stopping and dependable repeatability.
