Product Description:

Bosch Rexroth Indramat manufactures the MDD112D-N-030-N2M-130GB0, a synchronous motor in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts inverter-supplied current into precise rotary motion for positioning tables, gantries, and machining centers. The unit uses a standard housing, a plain shaft end, and standard rotor balancing, making it suitable for closed-loop industrial automation that requires repeatable speed and position. Its overall layout supports direct integration into motion systems that need accurate response during indexing, feed movement, and continuous axis control.

The motor delivers a continuous stall torque of 38.0 Nm, so it can hold a static load at standstill without exceeding its thermal limits. Its nominal operating speed reaches 3000 rpm, providing a common operating range for many servo-driven machine axes. A centering diameter of 130 mm helps align the motor accurately to gearboxes or mounting flanges and reduces the chance of radial runout during installation. Position data is transmitted through digital servo feedback, and the integrated multi-turn absolute encoder retains shaft position through power cycles so the axis can resume operation without a homing move.

All power and signal ports use side B connections, which keeps cable routing on one face of the machine and can simplify harness placement in tight assemblies. The motor uses size 112 with the extended D length code, giving the stator more active length for higher torque capability within the same product platform. A shaft seal helps keep coolant and dust away from the bearing area, supporting use in demanding industrial environments. The motor is supplied without a blocking brake, so any holding function at standstill must come from the drive system or external mechanics. This arrangement removes brake actuation from the motor package while keeping the shaft free for powered motion during normal operation.
