MDD025C-N-100-N2K-040FL0
The MDD025C-N-100-N2K-040FL0 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Sized for light-duty servo axes, the unit couples to a digital drive controller to generate tightly regulated torque and speed in automated assembly stations, laboratory handling modules, and compact packaging equipment. Its mechanical envelope follows the series mounting pattern, allowing installation in compact multi-axis frames. Its compact format is suited to equipment that needs fast response from a small motor package.
The motor supplies a continuous standstill torque of 0.90 Nm, giving stable holding force for small inertial loads without excessive heating. Its rated shaft speed of 10000 rpm supports short cycle times where high repetitive motion is required. A frame size of 025 matches the motor to correspondingly sized gearheads or belt transmissions. A centering shoulder of 40 mm aligns the flange to machine tooling and helps maintain concentricity during high-speed rotation. Electrical and feedback leads exit on the left side through a sealed connector, simplifying cable routing in tight cabinets. The connector position also helps keep cable bends manageable where adjacent axes leave little installation space.
The motor has an integrated absolute encoder for single-turn position data, and a secondary channel provides resolver feedback for commutation during dynamic acceleration. This arrangement supports accurate position tracking during repeated indexing and rapid speed changes. Because the unit is supplied without a blocking brake, any vertical axis must rely on external holding devices during power-off states. The rotor connects to the load through a plain shaft, avoiding key-induced stress concentrations and allowing quick clamp hub installation.
