Product Description:

The MDD090A-N-040-N2L-110GR1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, it converts three-phase power into accurate rotary motion so automated tooling, handling, and packaging stations can position loads repeatably. This operating role makes it suitable for axes that require repeatable starts, stops, and dwell periods under closed-loop control. Standard housing and balancing let the unit bolt directly to machine frames without extra vibration isolation. The single-ended layout saves rear clearance, and the protected front end supports direct coupling to gears or pulleys while keeping the installation compact.

At a standstill, the rotor sustains 3.7 Nm of continuous torque, enabling servomechanisms to hold position under static load without overheating or drift. Under commanded motion, it reaches a nominal speed of 4000 rpm, supporting high-cycle operations such as pick-and-place indexing. A factory-installed blocking brake supplies 6.5 Nm of holding force so vertical or safety-critical axes remain locked when system power is off. Accurate centering during assembly is provided by a 110 mm pilot diameter, and drive alignment is straightforward because the motor uses a plain shaft that avoids keyway backlash. The compact stator length keeps rotor inertia low, and the housing dissipates losses through natural convection.

Machine wiring is streamlined by the right-side connection that groups power, brake, and feedback leads into a single coded connector. This arrangement reduces cable clutter near the motor body and helps routing in crowded assemblies. Position and velocity information return to the controller through digital servo feedback (DSF), allowing tight current loops and rapid fault detection during operation. The compact overall depth associated with length code A helps multiple motors fit on common mounting plates without interference. Standard dynamic balancing controls residual vibration across the usable speed range, and the front sealing arrangement helps protect the bearing area from coolant splash during routine production.
