Product description

The Siemens 1FK6063-6AF71-1EB0 is a six-pole permanent-magnet synchronous servo motor from the SIMOTICS S 1FK6 family. It is designed for precise, dynamic axes in machine tools, production equipment and handling systems. For base version 1FK6063-6AF71, Siemens documents 3000 min⁻¹ rated speed, 6.0 Nm rated torque and 4.7 A rated current. Standstill torque at 100 K is 11.0 Nm, with 7.9 A standstill current. The motor provides 1.89 kW at its optimum operating point. Short acceleration phases are supported by 36 Nm maximum torque and 28 A maximum current, while the mechanically permissible speed is 6600 min⁻¹. Suffix 1EB0 identifies an EnDat absolute encoder with 2048 signal periods, a keyed shaft with runout tolerance N and a holding brake. Power and signal connectors rotate through 270 degrees. Standard mounting is IM B5, with IM V1 and IM V3 also permitted. This version is rated IP64. For replacement, compare the complete order number, encoder protocol, brake connection, shaft geometry, flange and connector position, then configure current and speed limits from the motor data. Siemens specifies 13.8 kg motor weight for the braked version. The 1FK6063-6AF71-1EB0 is suitable for repair, retrofit and preventive spares for existing Siemens servo axes.

FAQ

Frequently asked questions

Contact us
Does the Siemens 1FK6063-6AF71-1EB0 have a holding brake?

Yes. The Siemens data sheet assigns a keyed shaft with runout tolerance N and a holding brake to the exact 1EB0 suffix.

Which encoder is installed in the 1FK6063-6AF71-1EB0?

This version uses an EnDat absolute encoder with 2048 signal periods per revolution, designated encoder A-2048 by Siemens.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
