Product description

Siemens 1FT6084-8AC71-1EG0 is a SIMOTICS S synchronous servomotor from the 1FT6 series for machine axes requiring a motor with 20 Nm rated torque and a rated speed of 2000 min-1. Researched product data lists the 100-K design, natural cooling, mounting design IM B5 with installation positions IM V1 and IM V3, and power and signal connectors with a transverse outlet on the right. Siemens 1FT6084-8AC71-1EG0 has an EnDat 2048 S/R absolute encoder, also identified as encoder A-2048, and uses a smooth shaft with concentricity tolerance N. The documented configuration also includes no holding brake, vibration severity grade N, a labyrinth seal and protection rating IP64. These features identify the unit as a Siemens servomotor for an existing controlled axis, not a general-purpose three-phase motor. For replacement, compare the complete MLFB, shaft form, flange, connector direction, encoder evaluation, installation position and servo controller. The cable set, coupling, axis mechanics and released controller parameters must also suit the 1FT6 configuration. A known derating value of 10 percent due to the absolute encoder forms part of the technical classification and should be considered when checking output reserve. This motor is relevant where an installed SIMOTICS S axis requires the same 20-Nm class, connection arrangement and encoder type without changing platforms. The complete 1FT6084-8AC71-1EG0 identification remains decisive for same-type replacement.

Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

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.

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.
