Product Description:

The MDD112D-N-030-N2M-180PA3 is a synchronous AC motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers to deliver regulated torque and speed in industrial automation systems. The motor uses the D length code in a 112 frame housing, applies standard balancing, and has a single standard shaft end for direct load coupling. Its permanent-magnet rotor and stator winding arrangement support medium-inertia applications commonly found in packaging, printing, and material-handling equipment, where stable motion and repeatable response are required during continuous operation.

At standstill, the motor can supply 38.0 Nm of continuous torque, which is the thermal limit for holding duty or very low-speed operation. Under rated excitation, it reaches a nominal speed of 3000 rpm, making it suitable for applications that require fast indexing and repeatable velocity. A blocking brake provides 60.0 Nm when engaged, supporting controlled stopping and load holding on vertical axes. Accurate position reporting is provided by an integrated multi-turn absolute encoder. Its signals are transmitted as Digital servo feedback (DSF) through the motor-mounted connector, allowing closed-loop drive control without external transducers.

A centering pilot of 180 mm aligns the flange for accurate mounting, and all conductors exit on Side A, which helps keep wiring clear of rotating machine elements. The machine-side harness connects through a connector, keeping cable attachment compact and orderly at the motor housing. A shaft seal helps block coolant spray and airborne particles from entering the shaft area. The output shaft uses a keyway so pulleys or couplings can be secured against slip during torque transfer. This arrangement suits precision axes installed near conveyors, guarded tooling, or other machine sections where alignment and protected cable routing are important.
