Product Description:

The MDD025C-N-100-N2K-040ML0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers and converts controlled electrical input into rotary motion for positioning and variable-speed tasks in industrial automation. The motor fits compact multi-axis systems where small dimensions and high speed support rapid cycle times on packaging, pick-and-place, and electronic assembly equipment. Its compact format also helps reduce moving mass on short-stroke axes where quick response is important.

Its centering register measures 40 mm, which provides the reference diameter for mounting on the machine frame. Power and feedback leads exit on the left side, and the single connector interface keeps machine wiring compact. The rotor uses standard balancing, and the housing is a standard version for general cabinet installation. Continuous torque at standstill reaches 0.90 Nm, so the motor can hold a steady load without thermal overload under rated conditions. An integrated absolute encoder is included so the drive can read position data immediately after power-up. The motor is supplied without a blocking brake, so an external holding method is needed when the shaft must remain stationary, and because it has no shaft seal, it is best suited to clean or enclosed environments.

During dynamic operation, the rotor can reach 10,000 rpm, which supports high surface speeds on small indexing axes. Additional position feedback is available through resolver feedback, which can support tracking in high-temperature operating conditions. Frame size 025 corresponds to the motor's stator outer diameter, while length code C reflects the active core depth and thermal capacity. The shaft uses a keyway for positive torque transfer to pulleys or couplings, and the design omits a side-B shaft end to reduce overall length. This layout leaves more installation room behind the motor in tightly packed machine assemblies.
