The Bosch Rexroth R911277777 (MDD115D-F-020-N2L-130GA1) is an AC servo motor engineered for precise motion control applications. It supports an operational ambient temperature range of 0 to +40°C and altitudes up to 1000 meters. The unit is rated for a nominal speed of 2000 min⁻¹ and provides 57.0 Nm continuous torque at standstill. The design includes a standard housing and balancing, a centering diameter of 130 mm, and a plain shaft with a shaft seal for effective dust and lubricant isolation. Digital servo feedback ensures accurate rotor speed and position monitoring. The side-A housing features the main power connection via connector and integrates a blocking brake (1.9 kg, 45.0 Nm holding torque) with 24V operation, delivering 18 ms clamping and 55 ms release delays. The motor is resistant to diluted acids, condensation, and corrosion.

What’s the mechanical role of the 130 mm centering diameter and sealed plain shaft on MDD115D-F-020-N2L-130GA1?

The centering pilot ensures precise concentric mounting to gearboxes or adapter plates, minimizing runout. Its plain shaft with shaft-seal limits ingress and supports coupling/bell housing interfaces without keyways when backlash-free clamping hubs are preferred.

How does the 45 Nm blocking brake on MDD115D-F-020-N2L-130GA1 help vertical axes or E-stop conditions?

The brake applies holding torque when power is removed for preventing back-driving or drift on Z-axes and load-holding stations. It enables controlled stopping and secure load retention during servo disable or emergency halts.

What does the digital servo feedback in the MDD115D-F-020-N2L-130GA1 accomplish, and how does it influence precision?

It provides closed-loop position/speed feedback to the Rexroth digital drive for enabling tight commutation and repeatable positioning over the motor’s working range. Within the MDD series, DSF is the standard feedback option and integrates with Rexroth DDS/DKS controllers.

How does the Side-A connector orientation on MDD115D-F-020-N2L-130GA1 affect cable routing and service?

It fixes the connector exit relative to the flange for easing repeatable harness layouts in tight machine bays. It also improves strain-relief planning and separates power/feedback dress to meet EMC and serviceability constraints.

What ingress protection and insulation class are typical for MDD115D units, and why does it matter for MDD115D-F-020-N2L-130GA1?

Its IP65 and insulation class F supports installation in dusty or splash-exposed zones and are suitable for thermal endurance. Its profile helps maintain winding life and bearing protection during industrial duty cycles.
