Product Description:

The MDD025B-N-100-N2G-040ML0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it provides controlled rotary motion in compact multi-axis assemblies where high speed, low moving mass, and responsive servo behavior are required. The motor has size 025 with length code B, and its rotor uses the standard balancing class for this series. Its compact format supports installation in tightly spaced machine layouts where several servo axes may share limited mounting space. In automation cells, it is used to position light loads directly and support fast, repeatable motion.

The motor reaches a rated speed of 10000 rpm, allowing rapid cycle times in pick-and-place or spindle duties. At standstill, it can hold a continuous torque of 0.60 Nm, which indicates the maximum static load the drive can support while maintaining rated thermal limits. A centering diameter of 40 mm aligns the flange on the mounting surface to help minimize radial runout and improve coupling alignment. Power and feedback conductors exit on the left side through a plug-in resolver feedback connector, which supports position feedback and helps keep cable routing orderly when multiple axes are stacked. The connector arrangement matches the digital drive family used in Rexroth modular cabinets, so the motor fits neatly into compact control layouts.

The rotor is supplied without a blocking brake, so an external holding method is required if the load must remain fixed when power is removed. A keyway shaft transmits torque without slip, and the primary wiring port uses a sealed connector for a secure electrical interface. The motor employs a standard housing without a shaft seal, and the opposite side has no shaft extension, which helps reduce overall length. That layout is suited to clean, dry environments where a sealed shaft passage is not required. The simplified exterior also leaves direct access to the electrical connection and keeps the motor easy to integrate into compact machine sections.
