MDD025B-N-100-N2K-040GR0
The MDD025B-N-100-N2K-040GR0 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed as a rotary actuator for digital drive controllers, it supplies torque directly to small mechanical axes in assembly stations, inspection rigs, and pick-and-place modules. Its size 025 frame and length code B keep the housing short for machines with limited axial space. The compact format also helps when the motor must fit beside slides, sensors, or transfer tooling in dense automation layouts. In tightly packed equipment, the short motor body can also reduce overhang at the mounting face and support more rigid axis construction.
At standstill, the motor delivers a continuous torque of 0.60 Nm, indicating the thermal load it can carry while the shaft is locked. During motion, the winding supports a nominal speed of 10,000 rpm, which suits short indexing moves and other high-speed duty. Installation is centered on a 40 mm pilot diameter, so the flange seats accurately on matching machine plates. Power and feedback plugs are directed to the right side, which can simplify cable routing where space beside the motor is available. The output uses a plain shaft, side B has no shaft extension, and a molded connector combines the conductors in one interface.
Feedback is supplied by an integrated absolute encoder, so the drive receives position data immediately after power-up. A secondary channel uses resolver feedback to support stable speed evaluation at low velocity and during rapid response to command changes. That arrangement supports machines that need an immediate reference after power cycling and steady behavior during slow approach moves. Because the unit is supplied without a blocking brake, any suspended or back-drivable load must be held by external means or by drive torque alone. The shaft is fitted with a shaft seal, which helps limit dust or coolant entry along the shaft journal. Standard dynamic balancing and a standard housing finish remain consistent with the motor's compact dimensions and intended use on small precision axes.
