Product description

The Bosch Rexroth MSK030C-0900-NN-M1-UG1-NNNN is a permanent-magnet synchronous servo motor from the IndraDyn S series. This exact version carries material number R911308684 and combines the compact MSK030C frame with the high-speed 0900 winding. Bosch Rexroth documents 0.8 Nm continuous torque at 60 K winding overtemperature and 0.9 Nm at 100 K for this motor version. The corresponding continuous current is 1.5 and 1.7 A respectively. Up to 4.0 Nm maximum torque and 6.8 A maximum current are available briefly. Maximum speed is 9,000 min⁻¹. The Hiperface multi-turn absolute encoder with 128 signal periods provides precise position feedback within a suitable Rexroth drive architecture. The type code also specifies a plain shaft with shaft sealing ring, rotatable electrical connectors and a holding brake. The brake operates at 24 V DC and provides 1.0 Nm holding torque. The motor is self-cooled, specified for ambient temperatures from 0 to 40 °C and protected to IP65. Its compact construction suits dynamic axes with limited installation space and a clearly defined mechanical interface. Documented weight with holding brake is approximately 2.1 kg. For repair, retrofit or spare-parts stocking, both the complete MSK030C-0900-NN-M1-UG1-NNNN type code and material number R911308684 are decisive. Before replacement, the motor data, encoder version, brake control, shaft, connector orientation, mechanical mounting, permissible loads and IndraDrive controller parameters must be checked against the machine. Existing parameters may be transferred only from a secured configuration clearly belonging to the system. This enables targeted replacement without equating adjacent MSK030C versions with different windings or equipment.

FAQ

Frequently asked questions

Contact us
Which performance data apply to the MSK030C-0900-NN-M1-UG1-NNNN?

The motor provides 0.8 Nm continuous torque at 60 K, 4.0 Nm maximum torque and a maximum speed of 9,000 min⁻¹.

What must be checked when replacing the Bosch Rexroth R911308684?

Check the complete type code, material number, winding, encoder, holding brake, shaft, connector orientation, mechanical mounting and controller parameters.

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.
