Product Description:

The MDD025A-N-100-N2K-040ME1 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is used in compact automation axes where fast speed regulation and small dimensions are needed. The unit links directly to drive amplifiers through a connecting cable with a coupling unit and provides closed-loop motion during positioning tasks. This arrangement suits small handling systems and other compact machines that require repeatable starts, stops, and direction changes without adding much installation space.

The motor reaches a nominal speed of 10000 rpm, allowing high cycle rates for pick-and-place heads and spindle stages. At standstill, it provides 0.33 Nm of continuous torque, which is suitable for light holding duty without excessive heat buildup. A spring-applied brake inside the housing produces 1.0 Nm, so the shaft can remain fixed when power is removed. A centering diameter of 40 mm supports accurate mounting to standard flange patterns, and the electrical and feedback leads exit on the left side to help with dense machine layouts. The pre-assembled cable with its coupling unit supports straightforward connection, while the standard housing supports natural convection cooling.

The compact frame size of 025 with length code A helps reduce inertia, allowing the rotor to respond quickly to command changes while keeping vibration within the standard balancing grade. Position data is provided by an integrated absolute encoder, which gives the drive controller the feedback needed for controlled motion. The output shaft is supplied without a shaft seal, which reduces friction for high-speed operation, and it uses a keyway for torque transfer to pulleys or couplings. Only the drive side is machined, so there is no shaft extension on side B.
