Product Description:

The MDD025B-N-100-N2K-040PF1 is a compact synchronous servo unit manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive output into precise rotary motion for small axes in industrial automation. By combining a permanent-magnet rotor with electronic commutation, the device supports accurate positioning in assembly lines, handling modules, and other computer-controlled machinery. Its compact format also suits installations where limited mounting space must be balanced with responsive servo performance.

At its nominal rating, the rotor reaches 10000 rpm, a speed supported by the size 025 frame and the longer B-length stator package. Continuous torque available at standstill is 0.60 Nm, which provides a steady starting point for holding or slowly accelerating loads when the shaft is locked. Electrical feedback is provided by an integrated absolute encoder that operates together with resolver feedback for drive synchronization. Power and signal leads exit on the right side, and the factory supplies a connecting cable with a coupling unit so installation does not require a custom harness. Standard dynamic balancing helps reduce vibration during high-speed operation, and the housing follows the standard enclosure pattern used with MDD mounting flanges.

To hold the axis when power is removed, the motor includes a blocking brake rated for 1.0 Nm of static torque. The motor uses a 40 mm centering pilot and a single keyed shaft, and the keyway transmits torque without slip while the opposite side B end remains closed. Contamination ingress is limited by a shaft seal, which helps retain lubricant during high-speed operation. The closed shaft-end arrangement keeps the output interface straightforward for direct coupling to compatible gearheads or belt-drive components.
