Product Description:

The MDD090B-N-040-N2M-110GB0 is an electronically commutated servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and translates drive current into controlled torque and speed in industrial automation cells. By combining permanent-magnet excitation with integrated position sensing, the unit provides fast dynamic response for packaging lines, material-handling gantries, and indexing stations that must maintain repeatable motion under rapidly changing loads.

The motor reaches a nominal speed of 4000 rpm, enabling fast cycle times while maintaining feedback accuracy from its integrated multiturn absolute encoder. At standstill, it can deliver 7.2 Nm of continuous torque, so holding or low-speed positioning loads remain stable without overheating. Mechanical alignment is aided by a centering diameter of 110 mm, and all power and signal conductors exit on side B to keep cable routing consistent in gantry layouts. Balancing is factory-set to the standard grade, the housing uses the standard cooling sleeve, and the shaft is plain for backlash-free clamping couplings.

Position information is returned through Digital servo feedback (DSF), allowing the controller to close velocity and position loops with microsecond latency. The motor uses a front-mounted connector interface, so power and feedback cables attach without opening the housing. Frame size 090 and motor length code B create a compact envelope that fits crowded multi-axis machines. The shaft is fitted with a shaft seal to protect the bearings from coolant splash during washdown cycles, and the shaft end is supplied without a side-B extension to lower reflected inertia. The assembly is delivered without a blocking brake for applications that already employ external holding devices.
