Product Description:

The MDD025B-N-100-N2G-040GC0 is a synchronous servo motor produced by Bosch Rexroth Indramat as a member of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical input from the drive into precise rotary motion for tasks such as positioning slides, indexing spindles, or following cam profiles in automated machinery. Built with a standard housing and standard rotor balancing, the unit offers a compact solution that fits installations requiring quick acceleration and consistent velocity control.

This model is designed for high-speed duty, and its nominal shaft velocity reaches 10000 rpm, allowing short cycle times in light mechanical stages. Continuous torque at standstill is rated at 0.60 Nm, indicating the magnetic holding force the motor can deliver without overheating when locked in position. A centering diameter of 40 mm provides accurate flange alignment to the machine frame, minimizing radial runout. The motor has a frame size code of 025, and length code B indicates the active stack depth, thermal capacity, and inertia. Standard balancing keeps vibration within limits for high-speed operation, and the plain shaft design maintains a smooth coupling interface for precision couplers.

All electrical and feedback terminations are routed on Side A, and the supplied connecting cable with a coupling unit helps simplify cabinet wiring. Closed-loop control is achieved through a resolver feedback element mounted in the rear housing. For axes that rely on external mechanical locks or drive torque to hold position, the motor is delivered without a blocking brake, eliminating brake supply requirements. A sealing ring around the output end forms a barrier, and the motor is shipped with a shaft seal to limit lubricant migration into the stator cavity. The standard shaft end on the drive side and the absence of a side B shaft extension further reduce space usage and simplify mechanical integration.
