MDD025B-N-100-N2K-040GL0
The MDD025B-N-100-N2K-040GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into regulated shaft rotation for positioning or velocity loops used in pick-and-place axes, small spindle drives, or indexing tables. Its compact 025 frame and B length code support installations where limited mounting space and high operating speed are both important. The motor is suited to compact axes that need repeatable motion and stable response during frequent start-and-stop cycles.
The motor delivers a continuous standstill torque of 0.60 Nm, allowing holding force without overheating when the rotor is stationary. During motion, it reaches a nominal mechanical speed of 10,000 rpm, which supports fast cycle rates in small automated machines. Power and feedback conductors exit on the left side, which can simplify routing when the motor is mounted against a right-hand machine wall. The single-piece connector interface carries phase, protective earth, and sensor conductors, so separate hard-wiring is not required. Rotor position is reported through resolver feedback, allowing the drive to maintain accurate commutation and smooth control even where electrical noise is present. This feedback arrangement also supports stable operation across rapid acceleration and deceleration sequences.
A centering pilot of 40 mm provides accurate alignment in precision flange mounts. The stainless steel plain shaft couples through friction or collet hubs, and this shaft style works well with low-backlash coupling arrangements. A shaft seal helps protect the internal bearings from coolant splash or dust found in automated equipment. Position data for homing routines is supported by an integrated absolute encoder, which allows position reference to remain available after power cycles. For applications that rely on servo torque or external holding methods, the motor is supplied without a blocking brake, which reduces rotating mass. Standard dynamic balancing helps limit vibration transfer to nearby lightweight machine structures.
