Product Description:

The MDD041B-N-100-N2K-050GB1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed to interface directly with digital drive controllers, the motor supplies precise rotary motion for positioning, indexing, and light-duty feed axes in automated machinery. Its compact 041 frame and B length keep the weight and footprint low while still accommodating a blocking brake and feedback devices needed in closed-loop industrial motion systems. This format suits compact machine sections where quick response and accurate feedback are needed in limited installation space.

It reaches a nominal rotor speed of 10000 rpm, allowing fast cycle times when commanded by the associated inverter. At standstill, the electromagnetic design can deliver 1.35 Nm of continuous holding torque, so light loads remain supported without external gearing. Alignment to the driven machine is simplified by a 50 mm centering diameter that mates with standard flange recesses. Power and feedback cables exit on side B, an arrangement that leaves the front face clear for rigid coupling. A sealed connector interface carries the phase conductors and signal lines, allowing connection without hard-wired terminals at the motor housing. This layout also helps keep cable routing behind the motor in compact axis assemblies.

For position retention during machine idle or a safety stop, a blocking brake supplies 1.2 Nm of static torque and acts directly on the rotor shaft. Speed and position data are provided by the integrated absolute encoder, while secondary coarse detection comes from the internal resolver feedback channel. A fitted plain shaft is paired with a shaft seal to limit lubricant escape and airborne contamination. The feedback arrangement supports stable axis control during starts, stops, and low-speed motion.
