Product Description:

The MDD112C-L-020-N2M-130GA1 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, the unit converts command signals into controlled rotary motion for positioning, indexing, and continuous-duty axes in industrial automation. Integrated feedback and a built-in brake let the motor be installed directly on machinery without separate transducers or an external holding device. This arrangement helps keep the drive package compact on transfer systems, rotary tables, and feed axes where installation space is limited.

At standstill the motor supplies a continuous torque of 28.0 Nm, allowing it to support high static loads without overheating. During normal duty it reaches a nominal speed of 2000 rpm, which is the synchronous output rate under rated electrical conditions. Heat generated in this operating range is removed through a housing designed for surface cooling, so an external mounting plate or airflow path can carry thermal energy away from the stator. The flange’s centering register measures 130 mm, providing an accurate fit that helps control radial runout. All power and feedback conductors exit on side A, which can simplify cable routing in narrow machine frames.

For vertical or suspended axes, an integrated blocking brake provides a holding torque of 14.0 Nm to prevent motion after power removal. Shaft position is reported by an integrated multi-turn absolute encoder, and the drive closes its control loops through digital servo feedback (DSF) without requiring homing cycles. This feedback arrangement lets the controller retain position information through power cycles, which is useful on axes that must restart without returning to a reference mark. A plain shaft permits direct coupling with clamp hubs or keyed adapters, while an internal shaft seal helps keep dust and coolant out of the bearing cavity.
