Product Description:

The MDD025A-N-100-N2K-040PC0 is a compact member of the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a brushless AC servo unit for digital drive controllers, it converts three-phase supply energy into controlled rotary motion for pick-and-place heads, light conveyors, and laboratory automation stages. Its standardized housing, centered mounting pilot, and keyed shaft interface support straightforward installation in modular machine frames while maintaining the thermal and dynamic performance expected in high-throughput production cells. It supports closed-loop operation with high control bandwidth in low-inertia assemblies and miniature servo stages. That operating role suits applications that need precise starts, stops, and short travel moves in a small installation space.

Its mechanical output profile starts with a continuous torque of 0.33 Nm available at standstill, providing the baseline holding force for fine incremental moves. The rotor is balanced to the standard class, and the centering diameter measures 40 mm, allowing concentric seating in precision mounting flanges. Electrical and feedback connections exit on side A, and the power leads are supplied through a connecting cable with coupling unit, which supports orderly cable routing and simple connection to the drive system. High-speed operation up to 10000 rpm supports rapid indexing tasks where short cycle times are critical. This combination of compact size and high rotational speed is well suited to small axes that must cycle quickly without using a larger motor frame.

Position data are returned through resolver feedback, while an integrated absolute encoder supplies multi-turn angle information to the controller for startup referencing without motion. The shaft uses a keyway profile and is protected by a shaft seal that helps limit lubricant migration and airborne contamination. Because the motor is delivered without a blocking brake, external clamping or drive-torque holding must be used when power is removed. The motor has frame size 025 and length code A, which helps it fit densely packed multi-axis modules. Its standard housing also keeps the package compact for installations where available mounting space is limited.
