Siemens 1FT7105-5WF71-4KH1 is a permanent-magnet synchronous servo motor from the SIMOTICS S-1FT7 product family. Its water-cooled 1FT7105-5WF71 base version is designed for highly dynamic feed, positioning and machine axes. At the 100 K operating point, Siemens specifies a standstill torque of 90 Nm. Rated speed is 3,000 min⁻¹, rated power is 24.8 kW and rated torque is 79 Nm. The corresponding rated current is 49.45 A. The ten-pole motor version permits a mechanical speed of up to 6,000 min⁻¹; a maximum speed of 5,500 min⁻¹ is documented for operation with the inverter. Limits for the base version are a maximum torque of 230 Nm and a maximum current of 164 A. Further electrical values include a torque constant of 1.67 Nm/A, winding resistance of 0.05 Ω at 20 °C and rotating-field inductance of 1.0 mH. Efficiency at the documented operating point is 94 percent. Water cooling transfers the generated heat to an external cooling circuit, allowing high power density in a compact motor design. These values support selection of the correct Siemens motor and verification of the installed drive train. The final characters of the complete MLFB define the specific mechanical and electrical configuration. Before replacement, compare the mounting arrangement, flange, shaft end, power connector, encoder version, holding brake and temperature monitoring with the rating plate and machine documentation. Coolant supply, flow rate, connector position, inverter data and existing control parameters must also be checked. Matching only the base string 1FT7105-5WF71 is not sufficient for a safe replacement decision; the complete order number 1FT7105-5WF71-4KH1 is decisive.

The base version is documented with 90 Nm standstill torque at 100 K, a rated speed of 3,000 min⁻¹, rated power of 24.8 kW, rated torque of 79 Nm and rated current of 49.45 A.
The final characters define features including the connector, encoder, shaft and brake. The shared base version is therefore not sufficient; 1FT7105-5WF71-4KH1 must be compared in full with the motor and machine documentation.
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.
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.
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.
