Product Description:

The MDD025C-N-100-N2G-040FL0 is a brushless AC servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it translates command currents into rapid, accurate rotary motion for compact automation axes that require high dynamic performance.

At standstill the rotor sustains a continuous torque of 0.90 Nm, a value that dictates drive current and thermal limits. During service the shaft reaches a nominal speed of 10000 min⁻¹, enabling short-cycle positioning. The flange centers on a 40 mm pilot to maintain concentric alignment with machine frames. Power and feedback leads exit on the left side, and a single molded connector forms the electrical interface for quick exchange. Standard dynamic balancing minimizes vibration, while the C length code and 025 frame size define inertia and overall footprint. The housing follows the standard enclosure format used across the series, allowing identical mounting patterns among sibling models.

Additional construction details refine the performance profile. Position sensing is carried out through resolver feedback, which delivers absolute rotor angle immediately at power-up. The hardened steel shaft is a plain shaft; only the front end is available for coupling, so no extension exists on side B. Because the unit ships without a blocking brake, static holding must be supplied by the drive or an external clamp. No shaft seal is fitted, reducing friction and heat at elevated speeds, and size code 025 keeps mass low for densely packed multi-axis assemblies.
