MDD025B-N-100-N2K-040GC0
The MDD025B-N-100-N2K-040GC0 is a miniature synchronous servomotor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It uses size code 025 and length code B, and it is intended for digital drive controllers that require high-speed, precise rotary motion on pick-and-place heads, small tool spindles, or indexing tables in automated machinery. Its compact format also suits axes where low moving mass and fast response are important during repetitive motion.
This motor reaches a nominal speed of 10000 rpm, allowing rapid positioning cycles with minimal dwell time. At standstill, it delivers 0.60 Nm of continuous torque, so static holding force is available without thermal overload when the axis is held by current alone. Rotor position is reported through resolver feedback, which provides absolute angle information even after power loss. For fine resolution within one turn, an additional integrated absolute encoder is installed, so the drive receives detailed position data during low-speed control and restart. Mechanical output is transferred through a plain shaft, a configuration that avoids keyway stress points and eases coupling to small hubs or pulleys.
Mechanical interfaces are built around a centering diameter of 40 mm, and all power and signal leads exit on Side A so cable routing stays predictable. The stator is connected through a connecting cable with coupling unit, which permits quick disconnection during service without disturbing seals. Protection against oil or coolant ingress is provided by a motor front fitted with a shaft seal, and the device is supplied without a blocking brake to keep mass and moment of inertia low for fast acceleration. Standard balancing keeps vibration within ISO limits at full speed, and the standard housing design maintains thermal contact with the machine frame.
