Product Description:

The MDD112D-N-030-N2L-130GB0 is a synchronous AC motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for direct coupling to digital drive controllers, the unit supplies commanded torque for positioning and velocity loops in automated machines. The model uses motor length code D and motor size 112, and it has a standard housing with standard dynamic balancing. This combination supports rigid mounting and helps limit vibration during frequent starts, stops, and reversing moves. It is suitable for packaging, printing, and handling equipment that depends on repeatable servo motion.

The motor delivers a continuous standstill torque of 38.0 Nm, allowing it to hold loads without overheating when the shaft is stationary. Under rated excitation it reaches a nominal speed of 3000 rpm, providing synchronous mechanical output for constant-speed tasks and fast axis movement. Accurate mechanical registration with gearboxes or mounting flanges is aided by a centering diameter of 130 mm. Electrical power and feedback conductors are routed at the rear because the hardware is located on the Side B end of the stator and terminates through a keyed Connector. This rear connection arrangement can simplify cable routing where the front of the motor is occupied by a coupling or pulley.

The shaft interface is a plain shaft protected by a shaft seal that retains lubrication and blocks dust. For axes that depend on drive torque for holding, the motor is supplied without a blocking brake, so no electromagnetic brake mass is added to the rotor. Position and speed data are returned through digital servo feedback, allowing the controller to read exact rotor position during closed-loop operation. The mechanical layout also omits a second shaft extension, so output is provided only at the primary shaft end. This arrangement suits installations that do not require side-B power transmission.
