Product Description:

The MDD025B-N-100-N2K-040PE0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into rapid shaft motion for light-duty axes in assembly equipment and pick-and-place modules. Its compact housing allows the motor to fit beside other MDD units inside tightly packed automation cells. In synchronized motion systems, this type of motor supports accurate positioning, repeatable starts and stops, and stable speed control during frequent direction and load changes.

The motor’s nominal speed reaches 10000 rpm, enabling high-velocity positioning when the inverter supplies rated frequency. At standstill, it can deliver 0.60 Nm of continuous torque, which is suitable for small loads that still require controlled holding force. A centering diameter of 40 mm provides the primary locating surface on the mounting face and helps maintain coaxial alignment with brackets or gearboxes. Power, feedback, and brake conductors are routed on the left side of the frame, and a resolver feedback channel inside the integrated absolute encoder supports real-time position loops. The motor uses a connecting cable with coupling unit, which simplifies connection at the motor interface, and because it is supplied without a blocking brake, axis holding must be handled by the drive or an external clamp.

The shaft uses a shaft seal that helps limit lubricant escape and particle entry at the bearing journal. A ground steel output with a keyway transfers motion to pulleys or couplings without slippage, and the omission of a second shaft end helps keep the overall length short. Size code 025 and length code B give the motor a slim form that supports low rotating mass and quick response during acceleration. The sealed, keyed output is useful on compact axes where transmission parts must stay light while maintaining accurate coupling at the drive end.
