MDD025A-N-100-N2K-040FB1
The MDD025A-N-100-N2K-040FB1 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is a compact permanent-magnet servo motor intended for operation with digital drive controllers in factory automation. The unit converts controlled current from the drive into rotary motion that positions tooling or fixtures with high repeatability on small handling systems. Its size and response make it suitable for pick-and-place axes, miniature gantries, and spindle orienting tasks in automated assembly lines where accurate motion must be repeated through frequent cycles.
This model reaches a maximum operating speed of 10000 rpm, allowing short cycle times where fast reversals are required. At standstill, it can deliver 0.33 Nm of continuous torque, which is appropriate for light loads without excessive heat buildup. An electromagnetic brake is mounted on the rear flange and can hold up to 1.0 Nm, providing static locking during power loss or when the axis must remain in place. Power and feedback leads exit on Side B, which can help when the motor is installed close to linear guides or compact machine structures. Accurate mechanical alignment is aided by a 40 mm centering diameter, and startup is simplified by an integrated absolute encoder that gives position information immediately after power-up.
For cyclic motion profiles, the drive uses resolver feedback to track rotor angle for closed-loop velocity and torque control. The output is a plain shaft, so couplings or pulleys can be mounted without a keyway interface. Because the housing is supplied without a shaft seal, the motor is better suited to clean machine areas or to installations that use external sealing at the machine interface. This shaft arrangement works well with compact couplings and small transmission components where low mass and precise alignment are important.
