Product description

The Bosch Rexroth MSM031C-0300-NN-M0-CH1 is a permanent-magnet synchronous servo motor from the IndraDyn-S MSM series for compact and dynamic machine axes. The documented version has a rated power of 300 W and a rated speed of 3000 U/min. Continuous torque at standstill is 1.30 Nm. A multiturn absolute encoder is integrated for position feedback and records the absolute position over several revolutions. An electrically released holding brake with 1.27 Nm holding torque supports holding the axis within the intended machine operation. The motor is cooled by natural convection and requires no attached external fan. IP65 protection safeguards the housing in its installed condition against dust and water jets in the intended industrial installation environment. The specific variant sequence also identifies a plain shaft, cable outlet and a version without a shaft seal. Operation at an ambient temperature up to 40 °C is documented. This combination makes the MSM031C-0300-NN-M0-CH1 particularly suitable as a type-identical replacement in existing Bosch-Rexroth servo axes where power, encoder principle, brake and mechanical interfaces must be retained. Frame size 031 and motor length C are essential identification features. They help maintenance teams distinguish the unit clearly from similarly powerful motors in the same series. Before installation, check the complete type number, motor power, torque, encoder evaluation, brake control, power and feedback cables, connector pinout, shaft end, flange, coupling, direction of rotation, load profile and controller parameter settings against the machine documentation. Adjacent MSM versions can differ in power, winding, encoder, brake, shaft, seal or connection type. Matching individual performance values alone is therefore insufficient for a reliable replacement.

FAQ

Frequently asked questions

Contact us
Which feedback system does the MSM031C-0300-NN-M0-CH1 use?

This version uses a multiturn absolute encoder. For replacement, encoder evaluation, feedback cable and controller parameter settings must match the existing Bosch-Rexroth axis.

Which brake does the Bosch Rexroth MSM031C-0300-NN-M0-CH1 have?

The motor has an electrically released holding brake with 1.27 Nm holding torque. Brake control, voltage and the intended machine function must be checked before installation.

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.
