Product Description:

The MDD025A-N-100-N2K-040FL0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, this motor converts controlled electrical input into precise mechanical rotation for positioning, indexing, or velocity regulation within automated machinery. Its small frame and high rated speed support tight installation spaces and high cycle-rate stations common in electronics assembly, pick-and-place arms, and light conveyor modules.

The motor’s rated speed reaches 10000 rpm, meaning the rotor can complete ten thousand revolutions per minute under nominal electrical and load conditions, which allows short move times in fast-cycling equipment. At standstill, it can maintain a continuous torque of 0.33 Nm, which indicates the maximum static load the axis can support without overheating while motion is paused. A centering diameter of 40 mm aligns the housing precisely in a machine plate or adapter, helping maintain concentricity between the motor and driven mechanics. Wiring leaves the stator on the left side, so cable routing must accommodate that connection orientation. Position data is generated by the integrated absolute encoder, which returns an unambiguous shaft angle immediately after power-up and removes the need for homing routines.

The drive also reads resolver feedback, providing analog position information for stable closed-loop control during acceleration toward the rated speed. Mechanical coupling is through a plain shaft, which avoids keyways that could introduce imbalance at high rotational speed. The motor uses size code 025, so its mass and inertia remain low and allow the available torque to support quick starts and stops. For applications where the machine or downstream gearbox supplies static holding force, the unit is delivered without a blocking brake, which reduces overall length while fitting within the standard housing and connector format.
