Product Description:

The MDD112C-N-030-N2M-130GA1 is an AC synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotational motion that can be regulated in closed-loop automation axes. This operating principle lets the paired drive regulate torque, speed, and position during rapid indexing or synchronized transport tasks. The unit’s plain shaft transmits torque directly to couplings or gear stages, and the standard housing supports installation on machine frames or in production equipment such as pick-and-place systems and material-handling gantries.

The motor delivers a continuous standstill torque of 28.0 Nm, giving the axis enough holding force to resist static loads while energized. A rated speed of 3000 rpm supports high-speed servo operation across the normal duty range. Mechanical centering during assembly is simplified by a 130 mm centering diameter, and rotor mass is trimmed to a standard balancing grade to keep vibration within ISO limits. Power and feedback conductors exit on Side A through a keyed connector, which allows the motor to be disconnected without disturbing fixed cable runs. That cable orientation can simplify routing when the motor is installed with the output shaft facing the load. The motor has size code 112 and length code C, which correspond to its frame and lamination length.

An integrated blocking brake supplies 14.0 Nm of static torque, so vertical or load-holding axes remain fixed when system power is removed. Position information is provided by an integrated multi-turn absolute encoder that counts complete revolutions and reports them to the controller through digital servo feedback. Because the encoder stores revolution data, the axis can return to known positions after power cycles without a separate reference move. There is a shaft seal at the output end to limit dust and coolant ingress, and the shaft is provided only on the drive side so Side B remains clear for airflow or nearby sensing devices. Standard housing ribs conduct heat to the surrounding air.
