MDD025C-N-100-N2K-040FD1
Bosch Rexroth Indramat produces the MDD025C-N-100-N2K-040FD1 as part of the MDD Synchronous Motors series. The unit is a compact servo motor intended for mounting on digital drive controllers where precise rotary motion is required. In automated pick-and-place modules, indexing tables, or tool spindles, it converts regulated current from the drive into position-controlled torque, letting a controller synchronize mechanical movement with process commands. Its construction follows the standard housing and balancing profile of the series, supporting stable operation across the full speed range.
The motor provides a continuous standstill torque of 0.90 Nm, which indicates how much load it can hold without overheating when the shaft is controlled at zero speed by the drive. High-speed work cycles are supported by a nominal shaft velocity of 10000 rpm, allowing rapid indexing when paired with suitable gearing. Position retention during power loss relies on an internal brake rated at 1.0 Nm, which clamps the rotor through spring force until the circuit is energized again. All power and feedback lines exit on Side B, allowing cable routing away from the driven mechanics. Precise concentric mounting is achieved by a 40 mm centering diameter that aligns the stator with the machine frame.
Rotor position is monitored through resolver feedback, giving analog sine-cosine signals that remain accurate across high acceleration profiles. For startup homing, the motor also contains an integrated absolute encoder, eliminating the need to seek a reference marker. A factory-fitted connecting cable with coupling unit allows quick disconnection while preserving shielding continuity. Motion is transferred through a plain shaft, and because the design is supplied without a shaft seal, it is intended for environments where external contamination is already controlled.
