Product Description:

The MDD025B-N-100-N2G-040GD0 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it serves compact automation axes that require high rotational speed and precise feedback. In industrial equipment, it converts commanded current into rotary motion that can be coupled directly to small gear stages or spindles for accurate positioning and short cycle times. Its compact format suits handling units, indexing devices, and other installations where mounting space is limited but responsive servo control is still required.

At its nominal speed of 10000 rpm, the motor delivers a continuous stall torque of 0.60 Nm, providing steady low-speed holding force during closed-loop positioning. All power and feedback conductors exit on side B of the housing, and the supplied connecting cable with a coupling unit supports straightforward cable routing without a fixed plug on the stator. Motion data is provided by resolver feedback, allowing the controller to monitor rotor position and speed while the shaft accelerates or decelerates quickly. This feedback arrangement helps the drive maintain stable commutation and speed control during rapid changes in load or direction.

The mechanical envelope centers on a diameter of 40 mm, so flange mounts can be machined for repeatable alignment in small machine assemblies. The unit is supplied without a blocking brake, so the load must be held by drive torque or an external device when power is removed. A shaft seal helps limit lubricant migration and protects the internal bearings from splash, while standard balancing helps reduce residual vibration at high speed. The motor also uses the B length code, frame size 025, a standard housing, a single drive-side shaft end, and a plain shaft for custom clamping hubs or compact coupling elements. The plain shaft is suited to clamping connections where a keyed output is not needed.
