Product Description:

Bosch Rexroth Indramat manufactures the MDD112D-N-040-N2M-130GA2, a synchronous servo motor in the MDD Synchronous Motors series. It works with compatible digital drive controllers to convert electrical commands into controlled rotary motion for positioning axes, conveyor drives, and tool spindles in automated production cells. Its synchronous design supports closed-loop operation so the connected drive can regulate speed and position during changing load conditions. The motor uses frame size 112 with length code D, giving a mechanical envelope suited to mid-range gantries and packaging equipment where steady torque and repeatable positioning are important.

At standstill, the motor supplies a continuous torque of 38.0 Nm, so it can support heavy loads without external gearing. During motion, it reaches a nominal speed of 4000 rpm, allowing short cycle times while remaining within the thermal limits of the standard housing. An integrated blocking brake on the non-drive end provides a holding torque of 40.0 Nm, which helps prevent drift when power is removed. The flange uses a 130 mm pilot for accurate alignment with coupled mechanics, and the standard balancing helps reduce vibration during operation. Power, brake, and feedback wires exit on side A, which can simplify cable routing when the motor is mounted with a horizontal shaft.

Electrical terminations are carried on a keyed connector that resists rotation and seals to the frame. A separate channel routes the multi-turn absolute encoder signals through digital servo feedback, giving position resolution across 4096 turns without battery support. The output uses a hardened plain shaft with a radial shaft seal, and the design omits a second shaft end. With only one shaft end, couplings, pulleys, or similar drive components are mounted at the primary output side.
