Product Description:

The F46GEAA-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 automated machinery, it converts drive current into controlled rotary torque for indexing tables, packaging lines, and gantry feeds. The unit belongs to the manufacturer’s standard motor configuration and uses English mounting and shaft dimensions, which align with legacy NEMA frame layouts used in North American installations. In typical installations, the integrated 24 V holding brake secures the load when power is removed.

With a continuous stall capability of 61 lb-in, the motor can sustain rated torque without overheating at zero speed, while transient demands are covered by a peak output of 155 lb-in. Electromagnetic force is generated according to a torque constant of 11.0 lb-in/A, so the drive must supply 1 A for every 11 lb-in requested under operating conditions. Back electromotive force rises at a slope of 130 V/Krpm, a parameter used for sizing the DC bus voltage of the amplifier. The integral brake coil draws only 0.22 A at 24 V, enabling long battery-backed holding during emergency-stop events. There is no secondary feedback channel, so the drive relies on a single primary resolver or encoder for position closure.

The laminated steel stack is six inches long and uses ferrite poles that remain stable under elevated temperatures. A frame width of 4.25 inch matches compact machinery envelopes, and the housing mass of 27.4 lbs aids thermal soak without external cooling fins. The housing has an IP65 rating. The front end is supplied without a shaft seal to minimize friction during continuous duty. When the brake is engaged, a static holding capacity of 72 lb-in resists back-driving on vertical axes. The English shaft and foot mounting follow common U.S. dimensional conventions used in the series.
