Product Description:

The MDD025B-N-100-N2K-040GD1 is a synchronous servomotor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, this 025-frame unit supplies rotational power to axes that demand high-speed positioning in automated assembly, packaging, and test equipment. Its compact housing and integrated position transducer allow the controller to monitor rotor angle directly and issue precise current commands for closed-loop motion. The small frame also helps the motor fit machine sections where available installation space is limited.

Under continuous stall load, the motor delivers 0.60 Nm of torque while remaining within its thermal limits. When paired with a matched inverter, it can reach a rated mechanical speed of 10000 rpm, enabling rapid indexing on light tooling or feed spindles. A spring-applied holding brake is built in and furnishes 1.0 Nm of static torque so vertical axes can remain secured during power loss. The front flange includes a centering pilot of 40 mm, and the rotor is balanced to the manufacturer’s Standard grade to help reduce vibration at high speed. Housing and shaft sealing use the standard version for this frame size, which helps limit lubricant escape and fine dust entry.

Electrical and feedback interfaces are positioned on Side B, which can simplify cabinet layout because both the power cable and the feedback leads exit toward the controller through a connecting cable with a coupling unit. That arrangement can also help maintain cleaner cable routing in compact enclosures. Motion accuracy relies on the integrated absolute encoder, which supplies multi-turn position data to the drive, while the complementary resolver feedback channel provides high-bandwidth velocity signals during rapid acceleration. A plain shaft supports precision clamp couplings and helps maintain low runout at the coupling interface.
