The Bosch Rexroth MPN R911251295 (MDD115D-F-015-N2M-130GB1) is a digital AC servomotor featuring a size code of 115 and motor length code D. It incorporates M8 size tapped holes suitable for DIN 580 lifting screws. The motor is constructed with an F-type housing, a plain shaft with shaft seal, and a 24VDC blocking brake providing 45.0 Nm holding torque. An integrated multiturn absolute encoder and digital servo feedback (DSF) support precise position monitoring. With a centering diameter of 130 mm, nominal speed of 1500 min⁻¹, and continuous standstill torque of 57.0 Nm, this motor is engineered for mounting via flange with through holes or threads. The cabling is halogen and silicone free, resistant to greases, mineral oils, diluted lyes, and acids. Surface cooling angle connectors are not compatible with this model.

Frequently Asked Questions

What distinguishes the MDD115D-F-015-N2M-130GB1’s feedback for positioning accuracy?

It uses digital servo feedback (DSF) paired with an integrated multiturn absolute encoder for enabling closed-loop control with absolute position retention over multiple revolutions and after power cycles. Its combination minimizes homing routines and improves start-up repeatability in multi-axis lines.

Why is the 45.0 Nm holding brake important on MDD115D-F-015-N2M-130GB1?

The DC brake maintains axis position under power-off or E-stop for preventing back-driving on vertical or overhauling loads. It also reduces mechanical wear on external clamping systems during dwell periods.

How does the 57.0 Nm continuous stall torque on MDD115D-F-015-N2M-130GB1 translate to real applications?

The available electromagnetic torque supports mid-speed feed axes and indexers without derating in typical duty cycles. It makes it suitable for packaging seal jaws, printing roll drives and machine-tool feeds.

How does the Side-B connection and 130 mm centering diameter aid integration on MDD115D-F-015-N2M-130GB1?

Its orientation eases cable routing in compact cabinets and moving axes. Its 130 mm centering diameter aligns with standard Rexroth mounting geometries for straightforward mechanical interchange.

What is the role of the shaft seal and plain-shaft configuration on MDD115D-F-015-N2M-130GB1?

The seal limits ingress of contaminants and helps maintain bearing life in industrial environments. Its plain shaft simplifies coupling to gearheads or belt pulleys when keyed torque transmission isn’t required.
