The Bosch Rexroth MPN R911284203 (MDD115D-N-015-N2M-180GA2) is an AC servo motor featuring a brushless construction with lifetime-lubricated bearings and a standard housing that supports efficient heat dissipation through natural convection and surface cooling. It is equipped with an integrated multiturn absolute encoder for precise digital servo feedback and allows for continuous cyclic start-stop operations via electronic commutation. Technical specifications include a nominal speed of 1500 min⁻¹, continuous holding torque of 57.0 Nm, blocking brake rated at 60.0 Nm torque, centering diameter of 180 mm, and a standard shaft with seal and plain end. Electrical connections are provided through a side A connector, and the unit is suitable for use with digital drive controllers.

Frequently Asked Questions

What benefit does the 57.0 Nm continuous torque at standstill provide for the MDD115D-N-015-N2M-180GA2?

It sustains holding and low-speed feed forces without thermal overrun in indexing axes or tensioning applications. It plateau torque simplifies sizing for conveyors, rotary tables and robotic joints that dwell under load.

Why is the Side-A connector orientation advantageous in dense cabinets or gantry carriages?

Its routing keeps power/feedback leads clear of moving members for easing service loops and minimizing snag points. It also shortens cable runs to Bosch Rexroth drives for aiding EMC and installation time.

How does the plain shaft with shaft seal help in food packaging or machining environments?

Its plain shaft simplifies rigid couplings while the seal limits ingress of coolants, dust and washdown splash. It preserves bearing life and encoder integrity when paired with rated housings.

How does the nominal speed of 1500 min⁻¹ interact with gearbox ratios on MDD115D-N-015-N2M-180GA2?

It allows straightforward 1:1 coupling to 50 Hz-class mechanisms or torque multiplication through modest ratios. It helps balance inertia matching and torque demand on precision conveyors.

What role does the holding brake (60 Nm) play on vertical axes using MDD115D-N-015-N2M-180GA2?

The integrated blocking brake secures the load at rest or power-loss for limiting ballscrew back-drive. It reduces the need for external clamping, while control manages torque handover during release.
