Product Description:

The MDD112C-N-030-N2M-139GB2 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 controlled drive current into rotational motion for positioning axes, gantries, and transfer units in automated machinery. Its closed-loop operation supports accurate speed and position control in machines that require repeatable motion over long production runs.

The motor delivers a continuous standstill torque of 28.0 Nm, allowing it to hold static loads without overheating while energized. During dynamic cycles, it can reach a nominal speed of 3000 rpm, matching medium-speed machining or material-handling requirements. For emergency or power-off holding, the integrated blocking brake supplies up to 40.0 Nm of locking torque. The motor has a frame size of 112 and a length code of C. This geometry standardizes mounting dimensions across the series and supports consistent installation. Rotor position is reported by an integrated multi-turn absolute encoder, giving the drive controller absolute shaft angle information across multiple revolutions and removing the need for homing after power is restored.

Power and feedback conductors exit on the drive side because the connectors are oriented toward Side B, and the wiring interface uses a circular industrial connector for secure cable attachment. The rotor is built with standard balancing, so no additional counterweights are required when coupling to rigid loads. There is a shaft seal that blocks dust or coolant from entering the bearing cavity, which helps protect the bearings in enclosed production cells. A plain shaft without a secondary side-B extension mates to keyed or clamped couplings, while digital servo feedback electronics inside the housing report high-resolution speed data. The standard housing design and single shaft end also help the motor fit into compact drive chains.
