MDD025C-N-100-N2K-040GE0
The MDD025C-N-100-N2K-040GE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified for digital drive controllers, it is used on compact positioning axes, pick-and-place heads, and spindles where rapid speed changes and tight feedback loops are required. A standard housing and balanced rotor help simplify installation, while the 025 frame size and C-length stator keep mass low for lightweight gantry or robot-joint applications. This layout supports precise motion in machines where quick reversal and repeatable positioning are important.
The motor’s maximum working velocity is 10000 rpm, allowing high cycle rates with a suitable inverter. At standstill, it delivers 0.90 Nm of continuous holding torque, so the axis can maintain position without excessive thermal stress. Mounting surfaces are aligned by a 40 mm centering diameter, which helps keep couplings and pulleys coaxial during installation. Power and feedback conductors leave from the left side of the housing in a left-side connection arrangement that can simplify cable routing in compact machines. Rotor position is measured by an integrated absolute encoder, which provides position data immediately after power-up and reduces the need for a separate homing routine.
The motor also uses resolver feedback, providing analog sine and cosine signals for compatible drives. Torque is transmitted through a plain shaft, which works with clamp couplings and avoids the need for a keyway. A shaft seal helps limit the entry of coolant or debris so the bearing area remains protected during normal machine operation. The motor is supplied without a blocking brake, which reduces added mass and inertia at the rotor. This arrangement fits applications that already rely on external holding devices or drive-generated torque when the axis is stopped.
