Product Description:

The MDD025A-N-100-N2K-040GL1 is a compact servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is used with digital drive controllers, where it converts commanded current into precise angular motion for light pick-and-place axes, labeling heads, or spindle positioning tasks in automated machinery. Motor length code A keeps the overall envelope short for confined spaces. Its compact format suits installations where low moving mass and limited mounting space are important.

The motor’s centering pilot is 40 mm, providing an accurate fit against geared adapters or mounting flanges, while standard balancing minimizes residual vibration through the supported speed range. Power and feedback conductors exit through a keyed connector on the left side, simplifying cabinet cable routing. Continuous torque at standstill is rated at 0.33 Nm, indicating the force the shaft can deliver indefinitely without overheating when locked. A maximum mechanical speed of 10000 rpm allows rapid cycle execution on short-stroke mechanisms. Position data originate from an integrated absolute encoder, and servo loops receive high-resolution rotor angle information through resolver feedback. The housing follows the series standard design, and the plain shaft profile accepts collets or miniature couplings.

A blocking brake is included, and its holding capability reaches 1.0 Nm, so vertical or cantilevered loads remain secure during power removal. The brake and the absence of shaft keying help reduce torsional play during indexing. Contaminant exclusion is improved by a shaft seal, which helps limit ingress in packaging or electronic assembly areas. Frame size 025 keeps rotor inertia low, enabling quick acceleration and reversal with modest current peaks. The standard shaft end is present on side A only, which leaves the opposite end free of a projecting output.
