Product Description:

The MDD112C-N-040-N2L-130GA0 is a synchronous motor produced by Bosch Rexroth Indramat for use with digital drive controllers. It belongs to the MDD Synchronous Motors series and serves as a rotary actuator in automated axes that require rapid speed changes and accurate positioning. By converting the drive output into controlled mechanical rotation, the motor supports closed-loop motion in packaging lines, handling units, and machining centers. Its synchronous design lets the connected controller regulate torque and position accurately during indexing, transfer, and feed motions. This makes the motor suitable for axes that alternate between acceleration, dwell, and reversal without losing control stability.

At a continuous standstill torque of 28.0 Nm, the rotor can hold static loads without overheating, which helps maintain repeatable startup conditions after dwell periods. The design supports a nominal speed of 4000 rpm, so it can move between setpoints while staying within the magnetic flux limits of the motor. A centering diameter of 130 mm aligns the flange to gearboxes or fixtures with low runout, and the frame size code 112 corresponds to the motor's stator diameter. The length code C indicates a longer active section that increases thermal mass and supports higher intermittent torque than shorter versions. Standard balancing helps maintain smooth rotation when the shaft is coupled to machine elements.

Position data is supplied through digital servo feedback (DSF), allowing the drive to correct speed errors during each control cycle. Power and sensor leads exit on Side A, and the motor uses a molded connector to keep cable attachment compact and orderly. The plain output shaft is supplied with a shaft seal, which helps limit lubricant migration near the bearing area, and the motor has a shaft end only on side A rather than a second stub shaft. Because the unit is configured without a blocking brake, holding torque must be provided by the drive or by external mechanical hardware. A standard housing encloses the windings, and the plain shaft follows ISO fit tolerances for common coupling installation.
