Product Description:

The MDD090A-N-040-N2M-110PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current profiles into precise mechanical rotation for automated positioning and speed control tasks on production machinery. Its permanent-magnet rotor works with electronic commutation so the drive can generate rapid torque changes for packaging equipment, transfer units, and other coordinated machine axes. This arrangement helps the motor respond quickly to changing load demands while maintaining controlled motion.

The motor delivers a continuous standstill torque of 3.7 Nm, allowing it to hold or slowly move loads without overheating when current is maintained. It has a nominal operating speed of 4000 rpm, so rated torque is available at high rotational speed during normal operation. Mechanical alignment is aided by a centering pilot of 110 mm, and standard balancing helps keep vibration even across the coupling and bearing system. Electrical and feedback conductors exit on Side B through a plug-in connector, which supports orderly cable routing in compact machine layouts. The integrated multiturn absolute encoder supplies the controller with absolute position data over multiple revolutions, and the standard housing helps protect the stator windings from airborne contaminants.

The drive recognizes the motor through Digital servo feedback (DSF), which carries motor identification and high-resolution position signals over a serial channel. Motion is transmitted through a shaft with a keyway and a shaft seal, which supports positive torque transfer while helping limit oil or coolant ingress at the bearing face. The unit is supplied without a blocking brake, so any holding function at standstill must be provided by the drive or by external machine hardware. The compact A length keeps installation depth short, and the 090 frame size suits medium-power axes where mounting space is limited. A shaft end is provided only on the drive side, which reduces rotational mass at the non-drive end.
