Product Description:

The MDD025C-N-100-N2K-040GB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it converts drive current into rotary motion that can be scaled precisely within automated packaging, assembly, or handling equipment. The integrated absolute encoder supplies position data directly to the drive, enabling closed-loop velocity and position control without external transducers. This configuration positions the unit as an electromechanical actuator for high-speed industrial axes.

At a continuous standstill torque of 0.90 Nm, the motor can hold load inertia against gravity or process resistance without overheating. When commutated at its nominal speed of 10000 min⁻¹, it supports applications that require fast indexing or spindle-type rotation. The centering collar measures 40 mm in diameter, allowing precise seating in machine frames so that radial run-out remains minimal. Power and feedback conductors exit on the rear because the connection orientation is Side B; termination is completed through a keyed Connector that supports quick swap-out and maintains shielding continuity. Resolver feedback is routed through that same connector, and the housing remains standard, providing the normal convection path assumed by MDD-family thermal models.

Mechanical features complement the electrical profile. Standard dynamic balancing reduces residual vibration, and the frame length identified by code C pairs with the frame size 025 to keep overall mass low for agile motion. A sealed front bearing arrangement includes a shaft seal to guard internal parts against coolant or particulate ingress, while the drive end is supplied with a plain shaft and a standard single-ended configuration, leaving no shaft extension on side B. The motor is delivered without a blocking brake, so braking torque must come from the drive or external clamps. Position sensing relies on resolver feedback, which tolerates high temperatures and electrical noise encountered near inverters.
