Product Description:

The MDD112C-N-040-N2M-130PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts drive current into controlled rotary motion for positioning and velocity tasks in automated machinery. The unit uses a standard housing and standard balancing, making it suitable for general-purpose installation without additional counterweights or special flange preparation. This arrangement supports steady operation in machines that require accurate motion and predictable dynamic response.

The motor delivers a continuous standstill torque of 28.0 Nm, allowing static load holding without thermal overload. Under rated excitation, it reaches a nominal speed of 4000 rpm, so the drive can support rapid indexing while remaining within the magnetic limits of size 112 and length code C. Power and feedback conductors exit on side B through a sealed connector interface, which can simplify cable routing when the shaft end faces the machine. Accurate centering is supported by a front-face pilot diameter of 130 mm, which matches common gearbox and coupling bores. The connector layout keeps the cable exit organized and helps maintain a compact motor installation.

A blocking brake rated for 40.0 Nm is integrated to secure vertical axes when supply power is removed. Rotor position reporting is provided by an integrated multiturn absolute encoder, and velocity loops receive high-resolution data over digital servo feedback (DSF), eliminating the need for external sensors. Contamination ingress is limited by a shaft design with a shaft seal around the output shaft, and the keyway allows positive drive engagement with pulleys or couplings. The model is supplied without a side-B shaft extension, so the opposite side remains closed. Internal balancing keeps vibration within ISO limits during continuous duty, and the standard connector mates directly with compatible drive cables.
