Product Description:

The MDD025C-N-100-N2G-040MB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from an Indramat drive into rotary motion for compact axes that need fast response in automated equipment. Integrated feedback supports accurate commutation and stable speed control during repeated starts, stops, and position changes. This type of motor is often used on compact feed axes, pick-and-place units, and other mechanisms that depend on predictable servo response in a small installation space.

The motor can sustain 0.90 Nm of continuous standstill torque, which supports holding and low-speed trimming without thermal overload. Under rated excitation, it reaches a nominal speed of 10000 rpm for rapid positioning cycles on high-speed axes. The centering boss measures 40 mm, which helps align the motor concentrically with mounting plates or gearheads. Power and feedback leads exit on side B, and the electrical connection uses a keyed connector that mates with compatible Indramat cables. Rear-facing cable routing can also help keep wiring clear of nearby tooling and moving machine parts. Standard balancing, a standard housing, and the C length help the motor fit compact machine frames while maintaining smooth operation.

Position data are returned by resolver feedback, allowing the drive to maintain current vector control across the speed range. The motor is supplied without a blocking brake, so holding force during power loss must come from drive torque or an external clamp. This version uses the compact size 025 frame and a single output shaft with a keyway for positive torque transmission to the driven load. The shaft is built without a shaft seal, which suits clean, dry cabinets where exposure to liquids or heavy contamination is not expected. That arrangement is often preferred where the axis remains inside a guarded enclosure and contamination control is handled by the surrounding machine design.
