Product Description:

The MDD112C-N-040-N2M-130PB0 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is an AC servo motor intended for use with digital drive controllers where fast positioning and repeatable velocity are required. With its size 112 frame and length code C, the model fits medium-power axes in automated machining cells or material-handling equipment. This layout also suits indexing tables, feed systems, and transfer axes that require stable closed-loop motion during repeated start-stop cycles.

The rotor is dynamically balanced to the standard grade, and its centering register measures 130 mm, so fixture plates can be aligned precisely. At standstill, the motor can supply 28.0 Nm of continuous torque, while the windings are designed to reach a nominal mechanical speed of 4000 rpm under rated drive voltage. Power and feedback connectors are oriented on Side B, which helps keep cable routing consistent when the motor is mounted against a machine face. The stator terminals use a single Connector interface that simplifies external connections. The shaft is machined with a keyway for common hub couplings, and the free end on side A is the only output because no shaft end is provided on side B.

An integrated multiturn absolute encoder works with the drive’s digital servo feedback channel to deliver high-resolution position data after each power cycle. This feedback arrangement lets the control system retain position information and support accurate motion recovery after a shutdown. Because the motor is supplied without a blocking brake, any static load must be held by the drive or an external clamp. A labyrinth arrangement together with a shaft seal protects the bearings from coolant splash as the keyed shaft passes through the housing. The standard housing finish supports routine industrial use where airborne dust, light splash, and repeated operation place steady demands on the motor exterior.
