Product Description:

The MDD112B-N-020-N2L-180GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, it converts regulated AC power into controlled rotary motion for packaging lines, gantry systems, and material-handling axes. The housing, balancing, and shaft end are supplied in the standard configuration, and the rear of the rotor carries no secondary shaft, so installation matches other frame-112 machines without mechanical changes. This arrangement supports straightforward integration where consistent mounting and closed-loop motion are required.

The mounting interface includes a centering diameter of 180 mm that aligns the flange to gearboxes with minimal runout. Power and feedback conductors exit on Side A through a keyed connector, keeping cables clear of the load side. At standstill, the motor delivers a continuous torque of 17.5 Nm, allowing it to hold or slowly index a load without exceeding thermal limits. Under motion it reaches a nominal speed of 2000 rpm; this rating matches the 112 frame size and the winding layout associated with length code B, which adds active copper for higher torque density while preserving the same mounting pitch. That operating speed suits repetitive travel moves and indexing tasks in automated equipment.

An integrated blocking brake supplies 14.0 Nm of static torque when de-energized, preventing back-driving on vertical or suspended axes. Rotor position is reported through digital servo feedback (DSF), enabling high-resolution commutation without external sensors. A plain shaft is fitted, and a shaft seal retains lubricant while keeping dust and coolant away from the bearings. The standard housing, combined with the balancing grade, helps maintain low vibration across the speed range. These features help protect the bearing area and maintain stable position data during cyclic operation.
