MDD025B-N-100-N2K-040GC1
The MDD025B-N-100-N2K-040GC1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts electrical drive commands into precise rotary motion for compact positioning axes and light-duty spindle tasks in automated machinery. The integrated absolute encoder supplies position data directly to the controller, and the built-in blocking brake helps hold the load when power is removed. This combination supports controlled motion in applications where compact size, accurate feedback, and secure stopping are all required.
This unit delivers a continuous standstill torque of 0.60 Nm, which provides holding force for small inertial loads during dwell periods. Its rated speed of 10000 rpm supports rapid indexing and short cycle times in high-speed motion tasks. A centering diameter of 40 mm provides the pilot fit on the mounting flange and helps maintain accurate alignment during installation. Power and feedback conductors exit on Side A, which keeps both cable paths on one side of the motor. The connection is made through a connecting cable with a coupling unit, so the motor can be attached without direct rewiring at the housing. Standard rotor balancing reduces vibration during operation, and the standard housing supports convection cooling in clean, dry environments.
Position data can also be obtained through resolver feedback, which provides analog phase information for compatible control systems. The blocking brake applies 1.0 Nm of static torque to resist back-driving when the axis is at rest. The motor uses a plain shaft, which avoids keyway-related stress concentration at the shaft surface. A dedicated shaft seal helps keep lubricant inside the motor while reducing the entry of fine dust. The motor also uses size 025 with a B frame length, which helps it fit into compact machine layouts where installation space is limited.
