MDD025B-N-100-N2K-040GL1
The MDD025B-N-100-N2K-040GL1 is a motor for digital drive controllers created by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for rapid positioning tasks in industrial automation, this compact unit converts electrical input from a drive into precise mechanical rotation. Its frame follows the 025 size convention and the B length code, giving it a short axial package that fits tight machinery envelopes while still delivering the speed needed for high-cycle production lines. The compact housing also helps the motor fit indexing tables, feeders, and other small-axis assemblies where installation space is limited.
At standstill, the motor supplies a continuous torque of 0.60 Nm, providing stable force for holding or slow-speed moves without excessive heating. When energized by the drive, the rotor can reach a nominal velocity of 10000 rpm, a rating that supports fast indexing on lightweight axes. Position data are sampled by the integrated absolute encoder, while velocity loops can alternatively reference the embedded resolver feedback. This dual sensing arrangement gives the controller position and speed information for responsive motion control. Power and feedback conductors enter from the left because the electrical interface uses a side-mounted connector, which simplifies cabling in multi-axis cabinets. The motor is supplied with standard dynamic balancing and a standard housing, so vibration behavior and overall size remain consistent with the rest of the MDD series.
For load-holding duties, the blocking brake exerts 1.0 Nm of torque, preventing back-drive when the drive is disabled. Accurate mechanical alignment to gearboxes or couplings is aided by the centering diameter of 40 mm. The output shaft is protected against contamination because the front end is equipped with a shaft seal, and power is transmitted through a plain shaft that arrives without a second shaft extension at side B. This arrangement supports clean coupling to connected machine elements while keeping the motor footprint compact.
