Product Description:

The MDD025B-N-100-N2K-040FB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. As a compact size-025 unit, it supplies rotary motion for positioning axes and high-speed spindles in automated machinery where repeatable speed and position control are required. The motor uses a standard housing and balancing grade so the rotor runs smoothly during operation. Its purpose in industrial automation is to convert controlled current from the drive into precise rotational motion for small, space-sensitive applications.

With a continuous standstill torque of 0.60 Nm, the motor can hold light loads without overheating while stationary. During operation, it reaches a nominal speed of 10000 rpm, which supports short cycle times in indexing tables and compact tool drives. Mechanical alignment is aided by a centering diameter of 40 mm. Power and feedback conductors exit on side B through a sealed connector, which helps keep cable routing straightforward. Standard dynamic balancing reduces residual forces on the bearings, and the lack of a shaft seal lowers friction when an external enclosure already provides protection.

Position data are provided through resolver feedback, which supports commutation and fine-step control. The output end is a plain shaft, so it excludes keyways and helps reduce runout in precision couplings. The motor is supplied without a blocking brake, so an external clamping device is needed if holding torque is required when power is removed. The motor belongs to size code 025 and uses length code B, which gives it a short body for tight installation spaces. A standard shaft end on the drive side and the absence of a secondary shaft suit applications that transmit torque through a single output end.
