Product Description:

The MDD025A-N-100-N2G-040MD0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it delivers high-speed rotary motion to compact machinery such as pick-and-place heads, small spindle modules, and light conveyors in automated cells. Its compact housing suits installations where mounting space is limited and fast axis response is important.

The motor body uses size 025 with the short A length code. A centering diameter of 40 mm aligns the motor on standard mounting flanges for accurate mechanical positioning. The electromagnetic system supports a nominal operating speed of 10000 rpm, giving rapid response in indexing tasks and other high-speed motion sequences. At standstill, the windings can provide 0.33 Nm of continuous torque for low-speed positioning. Power and feedback conductors exit on Side B, which can simplify cable routing when the shaft faces the workstation. Motion data is returned through resolver feedback, an analog method that remains stable in electrically noisy environments. The housing follows a sealed aluminum design, and the lack of external cooling fins helps keep the profile narrow.

The rotor uses standard balancing, which supports smooth operation when the motor is directly coupled to compact gearheads or other precision drive elements. Electrical energy is supplied through a connecting cable with coupling unit, providing a fixed connection method for power delivery. The motor is delivered without a blocking brake, so static holding torque must be provided by the external drive or by the machine mechanics. Output torque is transferred through a keyway shaft, while the opposite side remains closed without a shaft end on side B. Because the front bearing runs without a shaft seal, the motor is intended for clean, dry enclosures rather than washdown areas.
