Product Description:

The MDD090A-N-040-N2L-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it pairs with modular inverters to provide closed-loop axis control in automated machinery. With a motor size 090 frame and compact length code A, the unit supplies rotary motion where high speed and moderate torque are required in packaging, material handling, and general factory automation. Its compact housing helps it fit machine layouts where installation space is limited but accurate motion control is still required.

The continuous torque at standstill is 3.7 Nm, meaning the motor can hold that load indefinitely without overheating when the shaft is locked. During motion, the rotor can reach a nominal speed of 4000 rpm, allowing rapid cycles while remaining inside the thermal limits of the standard housing. Position and velocity signals are returned through Digital servo feedback, so the drive can adjust current quickly to maintain commanded profiles. Power and encoder cables exit on Side B, and the mating interface uses a sealed Connector that supports orderly cable routing. Standard mechanical balancing helps reduce vibration at rated speed, which supports smooth running and limits transmitted forces to nearby machine components.

Mounting accuracy is aided by a centering pilot of 110 mm, which aligns the flange before the screws are tightened. The rotor interface is a plain shaft supplied with a shaft seal, so oil or coolant splash is less likely to reach the front bearing area. Because the motor is delivered without a blocking brake, an external holding method is required for vertical axes or other loads that must remain fixed when power is removed. The standard drive-side shaft end and the absence of a second shaft on the opposite face leave room for couplings or timing pulleys. The short A-length body also keeps mass and inertia low for responsive motion in dynamic applications.
