MDD025C-N-100-N2G-040MA0
The MDD025C-N-100-N2G-040MA0 is a small-frame AC servo unit from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for digital drive controllers and converts controlled electrical input into high-speed mechanical rotation for positioning or speed-control loops in industrial automation equipment. The device uses a C-length stator in the 025 frame size, giving it a shallow footprint for compact gantries, pick-and-place heads, and other space-limited assemblies where available installation depth is restricted.
It produces a continuous standstill torque of 0.90 Nm, allowing light loads to be held or accelerated without overheating while the shaft is locked. During motion, the rotor can reach a nominal speed of 10000 rpm; this high base speed suits low-inertia applications that favor rapid cycle times. Power and feedback conductors leave the housing on the designated Side A, where a single connector simplifies wiring inside crowded panels and keeps cable routing straightforward. Accurate mechanical alignment is supported by a centering flange that measures 40 mm in diameter, helping maintain concentric mounting to gearboxes, fixtures, or other coupled machine elements. The motor carries standard dynamic balancing so vibration levels remain within normal limits at full speed during routine operation.
Position data is supplied through resolver feedback, so the drive can close velocity and position loops even in electrically noisy environments. For holding duties after power removal, the unit is delivered without a blocking brake, making it suitable for axes that rely on external clamping or continuous drive torque to stay in place during stops. The single-ended shaft uses a keyway profile and is provided only on the front, while the enclosure is built without a shaft seal, so the coupling side must be protected from fluid ingress. A standard aluminum housing preserves thermal conductivity during intensive duty cycles and supports heat transfer away from the active parts.
