Product details

1.1 Nm / 0.47 kW synchronous servo, listed EOL

The 1FK70325AK711TB5 is the Siemens 1FK7 synchronous servo motor — a 3-phase AC unit rated 1.1 Nm continuous torque at 0.47 kW with a 6000 rpm ceiling, sized for the compact end of the SIMOTICS S family where a small-frame servo is driving a positioning axis, a small feed drive, or a packaging-station indexer rather than a main spindle. This code is listed lifecycle stage eol_hot, which means the official last-time-buy window has closed and the line is being run down — stock on the open market is what remains, and the realistic procurement path is independent distribution quoted against your RFQ rather than a fresh factory order.

Sourcing posture for a hot EOL servo

When a servo motor carries an EOL/HOT flag, the first question for the controls engineer is whether the machine builder has already validated a replacement — if not, the panel needs a contingency that lets a spare be pulled from inventory and dropped onto the shaft without re-doing the mechanical side. The 1FK70325AK711TB5's nameplate data (1.1 Nm, 0.47 kW, 6000 rpm) is the engineering identity you match against any successor; pinout, encoder resolution, and brake option all have to be cross-checked against the cabinet drawing before a swap is committed.

Frequently asked questions

How do I get pricing and availability for the 1FK70325AK711TB5?

Submit an RFQ quoting the order code, the quantity you need, and any nameplate match-up requirements (encoder type, brake, shaft). The distributor will come back with current pricing, the available lot, and traceable origin so you can confirm it against your bill of materials before committing.

What is the closest pin-compatible alternative to the 1FK70325AK711TB5?

There is no pin-compatible successor carried in this listing — any cross-reference has to be confirmed against the Siemens 1FK7 family catalogue with the same frame length, encoder, and brake option. The mechanical drop-in candidate is determined by the 1.1 Nm / 0.47 kW / 6000 rpm envelope and the connector layout on your specific variant, not by the order code alone.

What does the description on this Siemens servo motor say?

The listed description reads MOTOR SYNC 3AC 1.1NM 0.47KW 6000RPM — a three-phase AC synchronous servo, 1.1 Newton-metres of continuous torque, 0.47 kilowatts mechanical, 6000 rpm rated speed. That envelope is what you match against the machine builder's axis sizing when verifying a replacement.
