Product Description:

The MDD112C-N-020-N2M-130PB1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled inverter power into rotational motion for positioning and velocity tasks on automated machinery, transfer stations, and packaging lines. The model fits a modular drive system by using a standardized mechanical interface and feedback arrangement that work with compatible power modules and control loops. Its closed-loop operation suits axes that require stable response during frequent starts, stops, and speed changes.

The motor has a nominal speed of 2000 rpm, which is its continuous shaft rotation rate under rated conditions. At standstill, the motor can deliver a continuous torque of 28.0 Nm, and this value is useful when evaluating thermal load during low-speed or holding operation. A centering diameter of 130 mm aligns the flange with gearbox or machine frames and helps maintain concentricity during dynamic loading. Electrical and feedback terminations are routed on Side B through a single connector, keeping cable runs clear of the driven mechanics. Standard balancing and housing arrangements support smooth operation without additional vibration isolation or protective sleeves.

Position reporting is handled by an integrated multiturn absolute encoder working with the drive’s digital servo feedback channel, so the controller receives precise angle data across multiple revolutions without homing. This feedback arrangement also helps the drive retain position information after shutdown, which supports controlled restart behavior on axes that cannot be rehomed during every cycle. During power-off states, a blocking brake supplies 14.0 Nm of holding torque to help prevent axis drift on vertical loads. The output shaft uses a keyway profile for positive mechanical coupling, and a factory-installed shaft seal limits lubricant migration into the motor. Length code C and size 112 indicate the active iron stack and provide a balance between inertia and continuous power for medium-throughput servo axes.
