Product description

The Bosch Rexroth MDD065B-N-040-N2L-095GB0 is a digitally controlled AC servo motor from the Indramat MDD series. Its compact size 065 with length code B was developed for highly dynamic feed, positioning and handling axes. Winding code 040 indicates a rated speed of 4000 min⁻¹ for this motor size. At standstill, the motor provides 1.5 Nm continuous torque with natural convection and draws 3.5 A continuous current. The project planning manual also specifies 4.4 Nm theoretical maximum torque and 15.9 A peak current. A rotor moment of inertia of 2.2 × 10⁻⁴ kgm² enables rapid responses to command changes. Electrical data includes a torque constant of 0.43 Nm/A, winding resistance of 5.22 Ohm and winding inductance of 7.4 mH at 20 °C. The standard N housing is suitable for natural convection and additional surface cooling. Digital servo feedback handles commutation, speed and position feedback. Code N2L confirms standard balancing, no second shaft end and digital feedback. The 095GB0 section defines a 95 mm centering diameter, plain output shaft with shaft seal, power connector on side B and a version without a holding brake. IP65 protection, insulation class F and the permissible ambient range from 0 to 45 °C support direct operation in the machine area. For replacement, the type code, feedback, connector orientation, shaft design and absence of a brake must match the existing mechanics and the Indramat digital controller exactly. This keeps axis planning unambiguous and prevents variant confusion. The permanent-magnet, brushless design enables low-maintenance operation, while the low mass of 3.9 kg and compact rotor inertia support short acceleration and braking cycles in machine tools, printing machines or packaging systems.

FAQ

Frequently asked questions

Contact us
What performance data applies to the MDD065B-N-040?

The documented data for size 065B with winding 040 is 4000 min⁻¹ rated speed, 1.5 Nm continuous torque at standstill, 3.5 A continuous current and 4.4 Nm theoretical maximum torque.

What does the final code N2L-095GB0 mean?

It denotes standard balancing without a second shaft end, digital servo feedback, 95 mm centering diameter, a plain shaft, power connection on side B and no holding brake.

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.
