MDD025C-N-100-N2K-040GD0
The MDD025C-N-100-N2K-040GD0 is a compact synchronous servo motor developed by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it provides fast and repeatable rotary motion for positioning and cyclic tasks in automated machinery. In closed-loop axes, the motor converts electrical commands into controlled mechanical output so conveyors, handling modules, and light machining spindles can follow stable speed and torque profiles. Its compact format also suits installations where low moving mass and limited mounting space are important.
At stall, the rotor can deliver 0.90 Nm, allowing steady low-speed holding when cooling air passes over the housing. The shaft can accelerate to 10,000 rpm, a nominal speed suited for rapid duty cycles and short motion sequences. Accurate rotor position is maintained by the integrated absolute encoder, while mechanical alignment is supported by a centering diameter of 40 mm that fits directly into pilot bores. Power and feedback conductors exit on side B, which helps reduce cable congestion in narrow cabinets. The C length code provides additional active stack, while the 025 frame keeps the motor suitable for lightweight axes.
The motor is supplied with a connecting cable with a coupling unit, so installation only requires a matching connection at the drive. The control system receives resolver feedback for speed evaluation and commutation during operation, which supports stable response across changing load conditions. The shaft uses a plain shaft design and comes with a shaft seal, helping protect the mechanical interface from contamination while the load side rotates. No blocking brake is fitted, which lowers inertia for quick acceleration, and the absence of a side-B shaft end leaves more room around adjacent components in compact multi-axis assemblies.
