Product description

The Fanuc A06B-0268-B605 is an AC servo motor from the Alpha i series for dynamic axis applications in CNC machines and automated production equipment. The exact motor version is designated αiS 30/4000 and combines 5.5 kW rated power with 177 V motor voltage, 19 A rated current, and a rated speed of 3,000 min-1. The documented maximum speed is 4,000 min-1. Stall torque is 30 Nm and stall current is 31.7 A. The tapered shaft, integrated 90-V brake, and α64iA feedback system are particularly important for the mechanical and control-system identification of this B605 version. Further specified values include rotor inertia of 0.00819 kg·m², a torque constant of 0.95 Nm/A, and static friction of 0.8 Nm. The three-phase version operates at 200 Hz and is described with insulation class F and protection rating IP65. These details allow the motor to be checked precisely against existing axis data, amplifier assignment, and mechanical coupling. The electrical ratings also help determine whether the installed servo amplifier, motor cable, and brake control are designed for this motor version. Before ordering, operators should compare the complete A06B number as well as the shaft geometry, brake voltage, encoder version, connector orientation, mounting flange, and axis parameters. If the motor has already been removed, directly compare the nameplate and connector alignment before preparing the mechanical installation. A visually similar B705 or B805 version may differ in shaft and mechanical coupling and is therefore not automatically interchangeable. The A06B-0268-B605 is a clearly identifiable replacement for maintenance, repair stock, and time-critical recommissioning of existing Fanuc servo axes.

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.
