Product Description:

The MDD112C-N-030-N2L-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides closed-loop rotary motion for positioning tables, automatic assembly stations, and other industrial axes. When paired with a suitable servo inverter, the motor supports accurate speed and position control in compact multi-axis systems. Its overall description is already clear, so only minor wording changes are needed to keep the body smooth and grammatically correct.

Mechanical interfacing starts with a centering pilot of 130 mm, which allows precise mounting on the machine frame. Power and feedback cables exit toward the rear because the connection orientation is side B, helping keep the cable bundle away from tooling on the opposite face. A single connector plug carries the motor phases and encoder leads, which simplifies wiring and keeps the connection layout compact. When held motionless, the stator delivers a continuous stall torque of 28.0 Nm, so the winding can sustain that load within its thermal class. Velocity regulation is referenced to digital servo feedback (DSF), allowing the controller to receive exact position data for stable closed-loop operation. During operation, the rotor reaches a nominal speed of 3000 rpm, which supports fast indexing without overspeeding the mechanical system.

For static holding or emergency stops, an integral brake supplies 14.0 Nm of holding torque and engages automatically whenever the drive controller removes excitation current. The motor uses frame size 112 with length code C, which provides a high torque capacity in a compact housing. Dynamic power is transferred through a shaft with a keyway, while the opposite end remains closed in the standard single-ended arrangement. A shaft seal at the drive end helps limit coolant splash and dust ingress during operation. The balanced rotor and standard housing also support direct coupling to gearboxes or belt pulleys without requiring added vibration dampers.
