Product Description:

The MDD025B-N-100-N2K-040GF1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current from the drive into tightly regulated rotary motion for small actuators, feeders, or transport rollers in automated cells and laboratory equipment. Electrical position data is reported through resolver feedback, and that signal works with the integrated absolute encoder so the controller can track shaft position through the full revolution. Its compact format suits axes where limited installation space and repeatable start-stop behavior are important.

This model reaches a nominal speed of 10000 rpm, allowing rapid indexing when short cycle times are required. At standstill it can supply 0.60 Nm of continuous torque, which supports low-speed holding force without overheating the windings during normal operation. The integrated blocking brake adds extra static holding by delivering 1.0 Nm of brake torque when power is removed. Installation is aided by a centering diameter of 40 mm, which helps align the motor with gearheads or flanges. Power and feedback conductors exit on the right side, so the cable set can follow machine layouts that need side clearance near the mounting face.

Rotor and shaft parts use standard balancing to reduce vibration at high speed, and connections are completed through a connecting cable with a coupling unit that mates directly to the drive cabinet. The output end uses a plain shaft without a secondary shaft on side B, which helps conserve space in compact frames and leaves more room around adjacent machine parts. IP sealing at the front bearing is maintained with a shaft seal, while the windings and frame use a standard housing for motor size 025 with length code B. This compact arrangement fits tightly enclosed mounting positions without adding a second shaft extension.
