Product Description:

The MDD112C-N-030-R2L-130GA3 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive output into mechanical rotation for medium-inertia axes that require controlled motion and secure holding at standstill. Its housing uses a standard sealed design, and the shaft end is supplied in a single-ended configuration suited to inline couplings rather than through-shafts. This arrangement fits servo applications where repeatable positioning, smooth speed control, and a compact drive-end connection are important.

This unit delivers a continuous standstill torque of 28.0 Nm, permitting stable force production without overheating when the rotor remains locked under closed-loop control. For emergency and power-off stops, the blocking brake applies a static torque of 60.0 Nm, so vertical or suspended loads can remain motionless after power is removed. Under rated excitation it reaches a nominal speed of 3000 rpm, which is the synchronous operating point used by the drive for velocity control. Accurate feedback is obtained from its integrated digital servo feedback system, which transmits rotor position to the controller in real time. Mechanical alignment during installation is simplified by a centering flange that measures 130 mm in diameter, allowing direct mounting to compatible gearheads and machine frames.

The rotor is balanced to grade R, which limits vibration at high speed and helps protect the bearings. Power, brake, and feedback cords connect on Side A of the stator through a keyed industrial connector, keeping cable runs on one face of the machine and simplifying routing where the opposite side faces a mounting surface. A factory-installed shaft seal blocks coolant or washdown fluid from reaching the internal bearing grease, while the drive end uses a plain shaft for clamp couplings. Frame size 112 with length C places the motor in a larger housing within the MDD range and accommodates the brake and feedback hardware used on this unit.
