MDD025B-N-100-N2G-040GB0
The MDD025B-N-100-N2G-040GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotary power in compact robotic axes, pick-and-place heads, and other precision modules where fast acceleration is required. The unit uses the series' standard housing and standard dynamic balancing, which helps it fit tightly packed multi-axis layouts. Its compact format also suits machinery where low moving mass and short installation space are important.
At its rated operating point, the rotor reaches 10000 rpm, enabling high surface speeds for light tooling or indexing tables. The continuous torque at standstill is 0.60 Nm, so the machine can hold position during dwell periods without excessive heat buildup. A centering shoulder of 40 mm aligns the flange precisely with adjoining mechanics and helps reduce radial runout. All power and feedback conductors exit on side B through a sealed circular connector, which can simplify cable routing in tight enclosures. The motor is supplied without a blocking brake, so applications that need static holding torque must rely on external clamps or drive current. It uses a single plug-in connector, and the shaft end follows the standard series style without an auxiliary shaft at the rear.
The compact frame represented by size code 025 and length code B keeps mass low while still accommodating resolver feedback for real-time velocity control. This feedback method supports stable operation across a wide temperature range and does not require recalibration during normal use. The motor uses a construction with a shaft seal, which helps limit contaminant ingress around the output end. Torque is transferred through a plain shaft that connects directly to couplings or pulleys without keyways. This motor can be installed in densely arranged automation cells that do not use dedicated cooling hardware.
