MDD025C-N-100-N2G-040ML1
The MDD025C-N-100-N2G-040ML1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it receives commanded currents from an inverter and converts them into rotary motion for positioning or high-cycle tasks in automated machinery. Its elevated nominal speed and compact 025 frame make the unit suitable for pick-and-place heads, miniature spindles, and other equipment that needs rapid yet accurately controlled rotation. The motor is intended for digitally controlled axes where rapid response and accurate positioning are both important. The compact frame also helps it fit small moving assemblies with limited mounting space.
The motor provides a continuous standstill torque of 0.90 Nm, and it reaches a nominal speed of 10000 rpm. A centering diameter of 40 mm aligns the motor to mounting collars so the air gap remains even under load. Power and feedback leads exit on the left side, and the electrical interface uses a plug-in connector that simplifies cable routing in tight panels. Rotor position is returned to the drive through resolver feedback, enabling closed-loop control with high angular resolution. This arrangement supports stable motion during repeated starts and stops. A keyed shaft transfers torque directly to couplings or pulleys.
An integrated blocking brake provides 1.0 Nm of holding torque, which helps prevent axis drift when power is removed. The motor uses length code C, which gives it a longer active stack while keeping the frame narrow. It has standard balancing and a standard housing, so no special mechanical finish is indicated. The shaft is supplied without a shaft seal, reducing friction at the output end. A single shaft end is provided, with no extension on side B, which keeps the coupling close to the front bearing.
