MDD025C-N-100-N2K-040MC0
The MDD025C-N-100-N2K-040MC0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise shaft rotation that can be synchronized with motion profiles in pick-and-place units, indexing tables, and miniature gantries. Within an automation cell, it forms the electromechanical link between the controller and the load, supporting high positioning accuracy while maintaining the short cycle times demanded by modern production lines.
Its standstill torque is rated at 0.90 Nm, giving enough stall capacity for light linear slides and belt drives. A nominal speed of 10000 rpm allows rapid repositioning without gear reduction, while the rotor is balanced to the standard grade to limit vibration at high velocity. The mounting pilot uses a centering diameter of 40 mm, which supports repeatable alignment on modular flanges. Position data returns to the drive through resolver feedback, and the motor tracks rotor angle without external sensors. The C length code indicates a longer active stack that supports higher peak power for the 025 frame size. Standard housing construction dissipates heat by natural convection, and the design is supplied without a shaft seal to keep friction losses low.
All electrical terminations are routed on Side A, and the motor ships with a connecting cable with coupling unit that mates to the drive without crimping. Because it is delivered without a blocking brake, any vertical axis must rely on external clamping when power is removed. The output shaft uses a keyway profile in a single-ended shaft configuration to transmit torque to pulleys or couplings. This arrangement keeps the mechanical interface simple and matches common compact drive train layouts used in small automation equipment.
