MDD025C-N-100-N2G-040MB1
The MDD025C-N-100-N2G-040MB1 is a compact servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts command currents into regulated torque and speed for small positioning axes, indexing tables, and light spindle drives in automated lines. Its electrical and mechanical layout allows direct pairing with matching drive electronics, giving machine builders a repeatable rotary actuator that maintains accuracy under the rapid duty cycles common to pick-and-place, packaging, and electronics assembly equipment. This arrangement suits compact automation equipment that needs quick response and repeatable motion from a small motor package.
At the core of this model is a continuous standstill torque rating of 0.90 Nm, which is the sustained torque available when the shaft is energized but not turning. During motion, the rotor can reach a nominal speed of 10,000 rpm, allowing rapid indexing of light loads. The centering diameter is 40 mm, which aligns the housing to the machine frame and helps control runout. Power and feedback cables enter through a connector, and because the terminals are on side B, routing can be kept away from couplings or gearboxes on the drive face. Standard dynamic balancing reduces residual vibration. Length code C, size 025, the standard housing, and the single drive-side shaft end keep the unit compact for tight machine layouts.
The integrated blocking brake supplies 1.0 Nm of holding torque, so vertical or suspended loads remain fixed when the drive is disabled. Position feedback is handled by resolver feedback, which provides rotor angle information for sinusoidal commutation without added feedback electronics. The output shaft uses a keyway for direct attachment of pulleys or couplings. The motor is supplied without a shaft seal, so it is better suited to clean enclosures where fluid exposure is not expected.
