Product Description:

Bosch Rexroth Indramat manufactures the MDD112C-N-030-N2L-130GA3, a member of the MDD Synchronous Motors series for use with digital drive controllers in automated machinery. The unit converts commanded electrical input into controlled rotary motion for positioning tables, tooling spindles, and packaging axes that require repeatable movement. Direct feedback to the drive supports closed-loop torque and speed control, which helps the motor respond accurately during acceleration, deceleration, and steady-state operation. This operating style makes it suitable for machinery where axis motion must remain stable during frequent cycle changes.

Mounting accuracy is guided by a centering diameter of 130 mm, which aligns the stator housing with adjoining machine frames. At standstill, the motor delivers a continuous torque of 28.0 Nm, allowing it to support static loads without excessive heat buildup. When energized, the rotor reaches a nominal speed of 3000 rpm, which suits drive systems used for fast indexing and precise motion control. An integrated blocking brake provides 60.0 Nm of holding torque, helping keep vertical or suspended loads stationary when power is removed. Power and encoder connections are routed through a side A mounted connector, and position data is transmitted through digital servo feedback (DSF) for accurate closed-loop regulation.

The output shaft uses a shaft seal to help limit lubricant migration and reduce the entry of contaminants near the bearing area. The motor has a frame size of 112, and the C length gives the housing a longer active section than shorter versions in the same platform. Internal rotating parts use standard balancing, which helps maintain smooth running during normal machine duty. The shaft is supplied in a single-ended form, making it suitable for direct coupling to pulleys, gearboxes, or similar drive elements. The housing uses a standard mechanical layout, so it fits common mounting arrangements used across the series.
