Product details

Lifecycle flag and what it changes on the BOM

The 1FK70337AF211JB5: Where the line is built around a Siemens SINAMICS drive, the motor still pairs through the standard 1FK7 encoder and power connector family, so the cabling plan does not need to change just because the BOM line is now a stock-sensitive part.

Ratings in plain terms for the controls integrator

The 1.3 Nm continuous torque figure at 0.41 kW and 3000 rpm places this 1FK7 motor in the lower-torque bracket of the family — small-part handling, indexing tables, and short-stroke feeds are the realistic assignments, not main-drive axes. The shaft and connector arrangement follow the 1FK7 compact series, which means a replacement drive-side commissioning profile already in the project library can be reused without re-mapping the position controller. Because the part is eol_hot rather than a clean active line, panel documentation should flag the motor as a "spares-supported" BOM item: a shorter reorder cycle on the running units, and a one-time float set aside for the next planned shutdown.

Frequently asked questions

What does the 1FK70337AF211JB5 description string actually describe?

The on-record description reads ITE 1FK70337AF211JB5 / SIE 1FK70337AF211JB5 MOTOR,SYNC,3AC,1.3NM,0.41KW,3000RPM — a synchronous three-phase servo, 1.3 Nm continuous, 0.41 kW mechanical, 3000 rpm rated speed. That is the entire mechanical envelope on this catalog line; any encoder resolution, holding-brake option, or shaft detail lives on the data sheet rather than the order code string.
