MDD025B-N-100-N2K-040GD0
The MDD025B-N-100-N2K-040GD0 is a compact AC servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It acts as the mechanical element in a closed-loop axis when paired with digital drive controllers, supplying controlled rotary motion to indexing tables, packaging equipment, and light pick-and-place stations. High speed capability and integrated feedback allow the motor to provide precise position and velocity data to the drive, making it suitable for rapid duty cycles in industrial automation. Its compact format also supports use in equipment where available mounting space is limited.
Its centering pilot is machined to 40 mm, allowing concentric seating in flange mounts and minimizing radial runout. Power and sensor cables exit on side B, so cable routing can stay clear of the load shaft in compact machine layouts. At stall, the motor can sustain 0.60 Nm continuously, so the axis can apply that level of static holding or low-speed torque without overheating. Position reference is generated by an integrated absolute encoder, which removes the need for homing after power loss. Electrical hookup is completed through a connecting cable with a coupling unit that locks to the housing and provides strain relief during motion.
For installations that rely on external mechanical clamping, the unit is delivered without a blocking brake, which reduces inertial drag during fast reversals. Velocity control remains stable up to 10000 rpm, enabling short cycle times in spindle or feeder applications. The drive reads fine-angle information through resolver feedback, a sensor format that tolerates electrical noise and high temperatures. Contaminant ingress is limited because the bearing region is built with a shaft seal, which helps retain grease and protect internal components during washdown or exposure to airborne oil. This arrangement supports reliable operation in compact automation equipment with frequent start-stop motion.
