MDD025A-N-100-N2K-040FA1
The MDD025A-N-100-N2K-040FA1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded electrical current into controlled rotary motion for compact automation axes and pick-and-place systems. The unit uses a standard housing and a standard balancing grade, and its compact geometry makes it a direct mechanical interface between the drive amplifier and the driven load. This layout is well suited to machinery where the motor must fit close to the load while still supporting precise closed-loop positioning.
At standstill, it produces 0.33 Nm of continuous torque, providing stable holding force for light loads under closed-loop current regulation. During motion, the rotor can run at a rated speed of 10,000 rpm, which supports fast pick-and-place cycles and other high-speed positioning tasks. A blocking brake is included, and its static capacity is 1.0 Nm, so vertical axes can remain locked when power is removed. Accurate mounting is achieved with a 40 mm centering diameter, and all power and feedback conductors exit on side A through a keyed connector, which helps keep cable routing orderly. The integrated absolute encoder supplies multi-turn position data to the drive for controlled motion and position retention.
The motor uses size 025 and length code A, which helps save space in tight assemblies. Motion data is returned through resolver feedback, allowing the drive to calculate shaft angle even in electrically noisy environments. The output uses a plain shaft and is supplied without a shaft seal, so external sealing is needed in washdown or oil-splash areas. A single shaft end is provided, while the opposite side remains closed. This arrangement supports compact machine layouts without adding extra shaft hardware at the rear of the motor.
