MDD025C-N-100-N2K-040MD1
The MDD025C-N-100-N2K-040MD1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical input into precise mechanical rotation for positioning or velocity loops in automated machinery. The compact frame suits pick-and-place axes, small tooling spindles, and indexers that require repeatable motion.
The motor delivers a continuous standstill torque of 0.90 Nm, so it can hold or slowly move a load without exceeding thermal limits. Its nominal speed reaches 10000 rpm, giving fast cycle times when the drive commands full rated speed. A blocking brake is installed, and its holding capacity is 1.0 Nm, allowing vertical axes to remain fixed when power is removed. Mechanical fit is managed through a centering shoulder that is 40 mm in diameter, ensuring coaxial alignment with gearboxes or machine flanges. Power is transmitted through a shaft with a keyway, providing a positive connection to pulleys or couplings and helping prevent slip under acceleration. Integrated motor feedback supplies position data to the controller, while length code C and size 025 indicate the overall package dimensions. Standard housing construction is used throughout.
Electrical and feedback conductors exit on Side B, and the interface is a connecting cable with a coupling unit that helps cable routing in tight cabinets. Motion control accuracy is improved by the motor’s resolver feedback, which provides analog angle information across the full speed range. The unit is built with standard balancing to minimize vibration when paired with precision bearings, and it is supplied without a shaft seal, so the mounting location must exclude liquid spray. The shaft extends only on the drive side, while the opposite end is omitted to keep the envelope compact and leave room for auxiliary components.
