Product Description:

The MDD025B-N-100-N2G-040MD0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power into precisely regulated rotary motion for indexing tables, miniature pick-and-place axes, and other light-duty automation stages. Its size code 025 and length code B give it a short overall body that fits easily into crowded machine frames. The compact format also suits high-speed axes where limited installation space and low moving mass are important.

It reaches a nominal speed of 10000 rpm, allowing short cycle times in assemblies that demand rapid angular acceleration. At standstill, the motor delivers 0.60 Nm of continuous torque before thermal limits are reached. A centering shoulder diameter of 40 mm aligns the housing with gearbox or flange interfaces and helps maintain accurate mounting. Position data is generated through resolver feedback, an analog sensing method that remains stable in electrical noise and elevated temperatures. For safety stops, the unit is supplied without a blocking brake, so external clamping or drive-applied holding torque must secure the load whenever power is removed.

Electrical power and feedback conductors exit on the B side. The factory-installed connecting cable with coupling unit supports motor replacement without rewiring individual pins. Standard balancing and a standard housing help minimize vibration transmission to adjacent machine parts during operation. The rotor uses a shaft with a keyway for keyed hubs, and the opposite shaft end is left unmachined to keep the assembly short. Because the motor is supplied without a shaft seal, it should be installed where coolant splash and dust ingress are controlled by the machine enclosure.
