Product Description:

The MDD025B-N-100-N2G-040GL1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies precisely timed rotary motion that a drive can regulate in closed loop, making it suitable for small pick-and-place modules, indexing tables, and light gantry axes. Its 025 frame size and standard housing allow installation in confined spaces while still delivering the high speeds demanded by fast-cycle automation. The compact format also helps when the moving axis must keep inertia low and respond quickly to frequent starts, stops, and direction changes.

At the mechanical interface, the mounting flange presents a centering diameter of 40 mm for repeatable alignment with couplings, and the rotor uses standard balancing. During continuous stall, the motor sustains 0.60 Nm of torque, while the winding supports a nominal speed of 10000 rpm; these values are used when matching the motor to light, fast-moving axes. A blocking brake built into the rear end supplies 1.0 Nm of static holding torque for vertical axes or controlled stopping conditions. Contaminant ingress at the output end is limited because the shaft area is fitted with a shaft seal, which helps protect the bearing area in mildly dusty or oily environments.

Service connections are arranged for field wiring efficiency, with power and feedback cables exiting on the left side through a single circular connector. Motion feedback is provided by integrated resolver feedback, giving the drive rotor-position information across the full speed range without requiring a separate encoder package. The output interface is a plain shaft, and the motor is supplied without a side-B shaft extension, which simplifies coupling selection for pulleys or compact gearheads. This layout keeps the overall connection scheme straightforward and supports use in small machine assemblies where space around the motor is limited.
