Product Description:

The MDD112C-N-030-N5M-130GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to work with digital drive controllers, it converts three-phase electrical power into controlled shaft motion for indexing tables, packaging axes, and other industrial automation stations. The motor uses size code 112 and a standard housing, which supports installation on compatible Rexroth flange patterns without special mechanical adaptation.

The motor delivers a continuous standstill torque of 28.0 Nm, providing holding force for static loads while staying within thermal limits. Its nominal rotor speed reaches 3000 rpm, which suits medium-inertia axes operated by standard inverter-based drive systems. Mechanical alignment is supported by a centering diameter of 130 mm, which provides a repeatable pilot surface for flange mounting. Power and feedback conductors exit on side B, which helps keep cables routed away from the driven mechanism in rear-mounted installations. Position and velocity are reported through digital servo feedback (DSF), allowing closed-loop control inside the drive controller.

The rotor uses standard balancing for stable operation at speed when it is coupled through a keyed hub. An integrated multi-turn absolute encoder stores position across power cycles, so homing is not required after shutdown. The stator uses the C length code, which provides the active core length used for this 112 frame motor. A plain shaft with a factory-installed shaft seal helps keep contaminants out of the motor interior and supports clean coupling to adjacent machine elements. The unit is supplied without a blocking brake, so an external holding method is required when the shaft must remain locked with power removed. The rear connector interface keeps cable attachment compact at the motor end.
