The Siemens 1FK7044-4CF71-1UB0 is a permanent-magnet synchronous servo motor from the SIMOTICS-S 1FK7-HD series. This exact Siemens version is intended for dynamic feed, positioning and handling axes in machine tools and production systems. With 1.2 kW rated power, 4.5 Nm standstill torque at 100 K and 3000 U/min rated speed, the motor covers compact servo axes with high torque density. Maximum mechanical speed is 9000 U/min; Siemens specifies a maximum of 8050 U/min in converter operation. Documented peak values are 13.0 Nm torque and 12.1 A current. The motor uses natural cooling and IM B5 construction; vertical mounting positions IM V1 and IM V3 are also supported. This version uses a multi-pole resolver with DRIVE-CLiQ for position and speed feedback. The rotatable power connector simplifies cable routing inside the machine. The shaft has a feather key and tolerance N. A permanent-magnet holding brake with 4.0 Nm holding torque, 24 V DC supply and 0.5 A coil current forms part of the complete variant configuration. IP64 protection guards against dust and splashing water, while net weight is 7,702 kg. The short brake opening and closing times support clearly defined holding operations in cyclic positioning tasks. Replacement work must match the complete order number, shaft and encoder version, brake data, connector orientation, flange, mounting position and parameterisation of the existing SINAMICS drive system. Similar 1FK7 motors can differ in speed, encoder, brake or shaft despite sharing a frame size. Matching the complete MLFB therefore prevents mechanical or control-system mismatches.

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.
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.

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.
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.
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.
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.
