Product Description:

The MDD112B-N-040-N2M-130PA1 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled rotary motion for positioning and speed-regulated axes. This makes the motor suitable for automated assembly systems, packaging equipment, and material-handling gantries that require accurate starts, stops, and load holding. Its integrated brake and feedback hardware allow the drive to manage both motion control and standstill holding within the same motor package.

In continuous operation, the motor can deliver 17.5 Nm of torque at standstill, allowing the drive to maintain load without excessive current demand. During motion, it reaches a nominal speed of 4000 rpm, and the motor uses frame size 112 for medium-inertia applications. A 130 mm centering diameter helps align the flange with machine plates or gearboxes and supports accurate mechanical seating with minimal runout. Rotor position is provided by an integrated multi-turn absolute encoder, and the drive receives this information through digital servo feedback (DSF) for closed-loop correction of speed and position errors. The housing uses the standard self-cooling construction of the series, so no separate fan or liquid cooling circuit is required.

Dynamic holding is provided by a blocking brake rated at 14.0 Nm, and the electrical connections are arranged on side A of the housing for straightforward cable routing. Balance quality is standard, which supports smooth rotation when torque is transmitted through the keyed shaft. A shaft seal is fitted to help limit the entry of dust or coolant, and the motor uses a single-ended shaft without a side B extension. The assembly also uses a circular connector, motor length code B, and a keyway output for mechanical power transmission.
