Product Description:
The MDD112D-N-030-N2M-130GA2 servo unit is part of the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This brushless AC motor converts commanded current from a digital drive controller into controlled mechanical power for positioning tables, gantry axes, and high-cycle packaging equipment. Its construction supports rapid speed changes demanded in automated lines, while the internal encoder and feedback channels supply the drive with real-time rotor data necessary for regulated motion profiles. It serves as the electromechanical interface between the controller's PWM output and the load.
Mechanical alignment is simplified by a centering flange sized at 130 mm, while dynamic balance is kept to the standard grade for smooth rotation. The motor is arranged so that the power and feedback plugs face side A, and a sealed connector terminates both circuits for straightforward machine integration. Under continuous excitation, the rotor can hold 38.0 Nm of torque at standstill, and when driven to the nominal electrical frequency it reaches 3000 rpm. A D-length stator stack supplies the active iron needed for this output, and the integrated multiturn absolute encoder reports position across multiple revolutions without battery support.
A blocking brake is fitted for power-off safety, and it clamps the shaft with 40.0 Nm of torque whenever the release signal is absent. Closed-loop control data are carried through digital servo feedback, so the paired drive can modulate current with high resolution. The output end uses a plain shaft machined to the series tolerances, protected by a labyrinth and a molded shaft seal to limit the ingress of oil or coolant. With a frame size of 112, the motor keeps a moderate envelope and mass while the standard housing and shaft-end configuration omit a secondary shaft on side B, leaving the working face clear for couplings.
