Product Description:

The MDD025B-N-100-N2K-040FE0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It uses the 025 frame size with B length, which gives the motor a compact footprint for tight machine spaces. That size is suitable for compact feed axes, small handling units, and other installations where motor length affects available travel. Standard rotor balancing and a standard housing keep vibration behavior and mounting dimensions consistent. Designed for digital drive controllers, the unit converts electrical commands into precise rotary motion for positioning, indexing, and process control tasks in automated machinery.

It delivers a continuous standstill torque of 0.60 Nm, allowing stable holding force during static loads. A nominal speed rating of 10,000 rpm supports rapid cycles in light-duty axes and short move times in compact assemblies. Mechanical alignment relies on a 40 mm centering diameter, and all power and feedback conductors exit on the left side to support single-direction cable routing. Position data is supplied by an integrated absolute encoder, so the drive can recover the rotor angle after a power interruption without an additional reference move. This helps the motor fit applications where restart behavior and repeatable positioning are important.

The rotor uses a plain shaft, which suits applications that use clamp-style couplings instead of keyed connections. Because the motor is supplied without a blocking brake, external holding means are required for vertical axes or loads that must remain fixed when power is removed. Servo loops that use analog sinusoidal feedback can connect to the built-in resolver feedback element, which maintains stable position signals at high speed. Power reaches the unit through a connecting cable with a coupling unit, and the shaft end on side A has no shaft seal, so the motor is best used where coolant spray and fine particulates are not present. This layout is well suited to clean, enclosed machine areas where cable routing and coupling access must remain straightforward.
