Product Description:

The MDD112C-N-030-N2M-130PB0 is a three-phase synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded electrical vectors into precisely regulated mechanical torque. When paired with the appropriate drive, the unit supports high-cycle positioning applications in assembly cells, indexing tables, and material transfer systems across industrial automation lines. Its C-length stator and 112 size frame place it in the mid-range of the family, providing higher torque density than shorter variants while keeping installation dimensions compatible with existing mounting patterns.

The motor's centering diameter of 130 mm locates the housing precisely in the mounting flange, controlling runout during high-speed operation. All power and feedback lines exit on side B, and the sealed connector interface allows quick cable changes. Under rated excitation, the rotor can reach a nominal velocity of 3000 rpm, enabling direct coupling to gearless transmission stages. At standstill, it can deliver a continuous torque of 28.0 Nm, and this steady electromagnetic output keeps vertical or compliant loads in position without overheating.

The rotor position is measured by an integrated multi-turn absolute encoder, so the drive always knows the shaft angle even after power interruptions. Position data is transmitted over digital servo feedback (DSF), which reduces wiring complexity and allows high-resolution phase commutation. The output shaft is machined with a keyway, and this positive locking feature helps prevent slippage when high startup torque is applied. Because the motor is supplied without a blocking brake, any static holding duty must be supplied by the controller's current loop or by an external mechanical clamp. Standard dynamic balancing and a fitted shaft seal support smooth, contamination-free service life.
