MDD025C-N-100-N2G-040MF1
The MDD025C-N-100-N2G-040MF1 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is supplied for digital drive controllers that demand high-speed rotary motion in confined spaces. Within automated pick-and-place gantries or small spindle stages, this unit converts drive current into rapid shaft rotation so that the controller can position loads precisely in closed-loop operation. Its compact format suits machine sections where nearby tooling leaves little room for larger motor housings.
At the mechanical interface, the rotor is trimmed to a standard balance grade, and the flange provides a 40 mm centering diameter that locates the stator concentrically on adjoining machinery. Power and feedback conductors exit on the right side through a connecting cable with coupling unit, simplifying line routing in cabinets with limited clearance. Size code 025 and length code C set the active iron stack, which supports a continuous standstill torque of 0.90 Nm. When driven from a matched inverter, the motor reaches a nominal speed of 10000 rpm, allowing fast indexing without overshoot. The cable-based connection also helps when connectors cannot project outward into narrow machine spaces. A standard housing encloses the stator laminations, so no auxiliary cooling hardware is required.
An integrated blocking brake can generate 1.0 Nm to secure vertical axes during power loss, and rotor position is returned to the drive through resolver feedback for sinusoidal commutation. Resolver signals remain stable in electrically noisy industrial environments. The output shaft uses a keyway and a single-ended layout, leaving the opposite side free of peripherals. Because the assembly is supplied without a shaft seal, liquid exposure must be restricted at the installation site. This arrangement is better suited to clean, enclosed machine areas where direct spray or washdown is not expected.
