Product description
Siemens 1FT6044-1AF71-4EA1 belongs to the SIMOTICS S 1FT6 series and is designed as a permanent-magnet synchronous servo motor for dynamic feed, positioning and machine-tool axes. The naturally cooled 1FT6044-1AF71 base version operates at a rated speed of 3000 min⁻¹. At a 100 K temperature rise, Siemens specifies rated torque of 4.3 Nm and rated current of 2.9 A. Standstill torque is 5.0 Nm at 3.0 A, while 1.35 kW is available at the optimum operating point. For short acceleration cycles, the configuration manual specifies a maximum torque of 18 Nm and maximum current of 11 A. Maximum mechanically permissible speed is 7700 min⁻¹. The motor has four poles and an EnDat absolute encoder with 2048 signal periods per revolution. Siemens specifies IM B5 mounting with permitted installation positions IM V1 and IM V3, together with an IP65 protection rating. The version without a brake weighs 8.3 kg for this motor size; the exact connector and mechanical configuration is defined by the complete 4EA1 suffix. When replacing the motor, compare the rating plate, encoder type, connector orientation, shaft, flange and any fitted brake directly with the removed unit. Current limits, controller parameters and DC-link voltage must also match the installed axis. The clearly documented torque, current and speed values support selection of a like-for-like replacement. Winding resistance of 3.05 Ω at 20 °C provides an additional reference for electrical checks during commissioning and troubleshooting. The 1FT6044-1AF71-4EA1 is intended for service cases where power class, EnDat feedback, cooling method, mounting arrangement and protection rating must remain unchanged.

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.
