MDD025C-N-100-N2K-040FA0
The MDD025C-N-100-N2K-040FA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat as a member of the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit converts commanded current into proportional torque so that automated axes can accelerate, decelerate, and hold position with high repeatability on assembly stations, test fixtures, and light-duty pick-and-place modules. Its compact format suits installations where available mounting space is limited and low moving mass helps support quick response. It is well suited to short-stroke axes and small rotary units that need accurate motion without a large motor envelope.
The motor’s centering flange has a diameter of 40 mm, which provides a mounting pilot that positions the stator housing concentrically with machine frames. At standstill, it can generate 0.90 Nm of continuous torque, which suits small mechanisms that require steady holding force without overheating. A nominal shaft speed of 10000 rpm allows fast index moves when commanded by the drive. Rotor angle is reported through resolver feedback, giving the drive continuous position information for closed-loop control. The motor is supplied without a blocking brake, so any load that must remain stationary after power loss requires an external locking method.
Cabling exits on Side A, enabling straight connectors to clear the machine wall when the motor is face-mounted. The output element is a plain shaft, eliminating keyways that could concentrate stress during high-speed rotation. For applications needing multi-turn reference, an integrated absolute encoder supplements the resolver and provides position data immediately after power-up. Dynamic behavior is aided by standard balancing, which limits radial vibration and reduces bearing load at full speed. Because the unit is shipped without a shaft seal, the installation area should remain free of coolant splash or abrasive dust to preserve service life. This layout supports use in clean, enclosed machine sections where compact cabling and stable high-speed rotation are important.
