Product Description:

The MDD025B-N-100-N2G-040FC1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical power into rotational motion that supports accurate speed and torque regulation on compact axes in automated machinery. It is suited for small handling units and other applications where stable response and precise motion in limited installation space are important. Position and velocity are reported through resolver feedback, allowing compatible drives to monitor rotor angle during operation.

Mechanical mounting begins with a centering diameter of 40 mm, allowing precise alignment to gearboxes or machine frames. The rotor is balanced to the standard grade used for the series, which helps minimize vibration across the speed range. Electrical energy enters from connections on side A, and the factory-installed connecting cable with a coupling unit simplifies plug-in installation and helps maintain seal integrity. At standstill, the winding can deliver a continuous torque of 0.60 Nm, so the axis can hold light loads without overheating. Under rated excitation, the shaft reaches a nominal speed of 10000 rpm, which suits high-throughput pick-and-place heads or spindle feeders. The shaft end has a single plain output with no second shaft on side B, and because the motor is supplied without a shaft seal, external protection is needed when oily contaminants are present.

The motor size code is 025 and the length code is B, giving a compact envelope that helps keep inertia low for dynamic profiling. A blocking brake is integrated and provides a holding torque of 1.0 Nm, so suspended or vertical loads can remain fixed during power-off states. The motor uses a plain shaft, which simplifies press-fit couplings and avoids keyway stress concentrations. A standard cast housing encloses the stator and windings, and the plain end configuration leaves side B free for encoder clearance or airflow. The compact housing also helps the motor fit into tightly spaced machine layouts where installation room is limited.
