MDD025B-N-100-N2K-040PL1
The MDD025B-N-100-N2K-040PL1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise rotary motion for positioning and speed-regulated axes in industrial automation equipment. The housing uses the standard version of the series, and the rotor is factory-balanced to support smooth running during high-speed operation. In automated machinery, this motor can serve small transfer axes, compact handling units, and other mechanisms that need repeatable motion in a limited installation space.
Its maximum speed reaches 10000 rpm, which supports very fast axes such as spindle units or pick-and-place heads. At standstill, the motor can deliver 0.60 Nm continuously, so it can handle low-speed motion or holding duties without excessive heat buildup. A 40 mm centering diameter helps align the motor with matching mounting faces during installation. Power and feedback conductors exit on the left side through a sealed connector, which can simplify cable routing around nearby moving parts. Size code 025 indicates a very small motor envelope that fits compact machine layouts where space around rails, tooling, and guards is limited.
For power-off holding, the blocking brake provides 1.0 Nm of torque, which is suitable for lightweight vertical or indexing axes. Motion control uses resolver feedback, supplying analog angle signals across the speed range for stable closed-loop operation. Mechanical output is delivered through a keyway shaft, allowing positive torque transfer to a coupling, pulley, or similar drive element. A shaft seal at the output face helps keep dust and coolant away from the bearing area while retaining internal lubrication during operation. This arrangement is useful in machines where the motor must remain compact while still providing secure torque transmission and dependable feedback.
