MDD025C-N-100-N2K-040GA1
The MDD025C-N-100-N2K-040GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts the three-phase output of an inverter into precise mechanical motion for positioning tables, small spindles, or indexing stations on automated lines. The design uses a plain shaft and a standard housing so it can fit into tight machine frames without auxiliary adapters.
At standstill, the rotor delivers a continuous torque of 0.90 Nm, giving stable force for holding or slow creep moves on light-duty axes. During normal operation, it can accelerate to a nominal speed of 10000 rpm, which supports high cycle rates in material-handling or tooling tasks. Position information is provided by an integrated absolute encoder, allowing immediate reference on power-up and eliminating external switches. To secure the axis when power is removed, a blocking brake produces 1.0 Nm of static torque. Power, feedback, and brake conductors leave the motor on side A, which helps keep cable routing consistent when the flange faces the workspace. Balancing uses the standard grade, and the housing follows the standard form factor.
A centering diameter of 40 mm aligns the motor precisely against the machine mounting face and helps preserve concentricity at high speed. Closed-loop velocity control is supported by resolver feedback, which the drive can use for interpolation during operation. Electrical termination uses a keyed connector that mates with the series cable sets and maintains signal integrity during vibration. A shaft seal keeps lubricant inside the bearing region and helps block coolant splash. The motor has size 025 with length code C, so it remains compact for small-axis installations while still supporting the installed feedback and brake functions.
