Product Description:

Bosch Rexroth Indramat manufactures the MDD112B-N-030-N2M-130GB0 synchronous motor for digital drive controllers. As part of the MDD Synchronous Motors series, it converts commanded current into rotary torque for automated axes. When paired with Indramat power modules, it supports closed-loop motion in assembly lines, material-handling systems, and packaging equipment. An integrated multiturn absolute encoder returns position data so the controller retains rotor angle after power loss. The housing follows the series standard construction and mounts directly to the machine frame.

The mechanical interface uses a centering diameter of 130 mm, which helps align the motor on the mounting surface. At standstill, the motor can exert 17.5 Nm of continuous torque for holding loads that remain under drive control. It reaches a nominal speed of 3000 rpm, so it can support fast axis movement in repetitive duty. Power and feedback conductors exit on side B, and a keyed connector keeps electrical attachment secure. The output is a plain shaft with a shaft seal, which helps retain lubricant and limit contaminant entry. The unit also has no secondary shaft end, which keeps the overall length more compact.

The motor uses standard balancing, which helps maintain smooth rotation and stable bearing operation during normal service. Frame size 112 gives the motor its mechanical envelope, while length code B provides a longer magnetic stack that supports higher torque from the housing size. Command information is processed through digital servo feedback, allowing the drive to manage current, speed, and position with high resolution. The unit is supplied without a blocking brake, so any static load holding during power-off must come from the machine mechanics or the drive system. Its standard aluminum housing also supports even heat dissipation across the motor body.
