Product Description:

The MDD025A-N-100-N2G-040FA0 is a compact motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It functions as a direct drive element in automated positioning, labeling, and pick-and-place stations where high repeatability and low rotor inertia are required. By translating command currents from the drive electronics into rapid mechanical rotation, the unit supports tightly coordinated multi-axis motion in factory lines and other industrial automation cells. This arrangement suits small servo axes that need fast starts, short settling times, and accurate response to changing commands.

Its mechanical core uses a centering diameter of 40 mm, along with motor size code 025 and the shortest construction length indicated by motor length code A. Standard balancing keeps vibration low across the speed range so the rotor can reach a nominal velocity of 10000 rpm without excessive bearing load. Continuous stall torque is 0.33 Nm, which provides suitable static force for miniature grippers and feed rollers. Power and feedback conductors exit on side A, and a shielded connector supports plug-in installation in dense control cabinets. Orientation data is returned through resolver feedback, which supports sinusoidal commutation and stable position interpolation during rapid motion changes.

For installations that rely on the drive to hold position electrically, the motor is supplied without a blocking brake, so external locking or drive torque must secure the axis when power is removed. The shaft arrangement uses a standard single-ended design with a plain shaft and comes without a shaft seal, making it suitable for clean, dry enclosures where ambient oil spray is not expected. A standard housing and a shaft end without a side B extension keep overall mass low and leave space for adjacent sensors or couplings. Because the motor does not include a brake or shaft seal, it is better suited to enclosed machine sections than to applications that expose the drive end to contaminants.
