MDD025B-N-100-N2K-040MR0
The MDD025B-N-100-N2K-040MR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it is intended for high-speed positioning and velocity control in automated machinery where compact size and quick acceleration are important. Its small format makes it suitable for light-duty axes in equipment such as packaging systems, electronic handling units, and other machines that require responsive motion in limited installation space. It is suited to applications that need short travel cycles and consistent speed regulation during repeated motion.
This model develops a continuous standstill torque of 0.60 Nm, which is the load it can hold at standstill without thermal overload when the rotor is locked. During operation, it reaches a nominal rotor speed of 10000 rpm, supporting fast cycle times on light-duty axes. Mechanical centering is handled through a 40 mm pilot diameter that aligns the housing with adjoining machine parts. Power and feedback conductors exit on the right side and terminate through a plug-in connector, which helps keep cable routing orderly. The housing uses the standard enclosure style for this series, and the resolver-based feedback system is supplemented by an integrated absolute encoder for single-turn position data.
The motor is supplied with no blocking brake, so external clamping or drive torque must hold vertical loads when power is removed. Position feedback is provided through resolver feedback, which offers stable signal transmission in electrically noisy environments. With size code 025 and length code B, the motor keeps a compact footprint while providing the active length needed for the stated torque. The output shaft uses a keyway profile and is delivered without a side B overhang, which helps avoid interference in tight assemblies. A shaft seal is not installed, so protection against contamination depends on the enclosure of the host machine.
