MDD025C-N-100-N2G-040GF0
The MDD025C-N-100-N2G-040GF0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. It delivers rotary motion for small positioning axes, pick-and-place heads, or indexing tables where high spindle speed and precise feedback are required for closed-loop automation. The size 025 frame with length code C gives the motor a compact package for machines with limited installation space. It is intended for servo applications that need quick response without the mass of a larger motor.
This model sustains a continuous standstill torque of 0.90 Nm, allowing the drive to hold load without overheating during dwell phases. Under rated excitation, it reaches a nominal velocity of 10000 rpm, so it can support rapid cycles when paired with properly sized gear or belt transmissions. Rotor position is reported through resolver feedback, a sensor format that tolerates electrical noise while providing analog angle data for the drive control loop. Power and feedback conductors exit on the right side, which suits cabinet layouts that favor horizontal cable runs. The motor ships with a connecting cable with a coupling unit, which simplifies installation because no extra field-installed connectors are required. A standard housing and balanced rotor help limit vibration during repeated high-speed operation.
A centering diameter of 40 mm aligns the flange precisely on machine frames, supporting accurate motor placement. The motor is supplied without a blocking brake, which avoids residual drag during high-speed acceleration sequences. The drive end uses a plain shaft without a keyway, supporting clamp-style couplings that help reduce backlash. Contaminant ingress at the journal is limited by a shaft seal, making the unit suitable for lightly dusted enclosures. The shaft end on side B is omitted, and the standard balancing grade helps limit radial loading on the bearings as rotor speed increases.
