Product Description:

The MDD093C-N-040-N2L-110GR2 is an AC synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In a digital drive system, it converts electrical energy into controlled rotary motion for positioning axes, packaging units, and material-handling stations. The model belongs to the 093 frame class and is built in the C-length configuration, giving the motor a higher rated speed while retaining a familiar mounting interface. It also integrates directly with Rexroth power modules and encoder interfaces, making it suitable for closed-loop applications that require repeatable acceleration and precise position control. Because it is a synchronous design, the drive can maintain stable speed response during rapid changes in load and direction.

The motor reaches a nominal speed of 4000 rpm, enabling rapid duty cycles when it is paired with low-inertia loads. Accurate mechanical alignment is aided by a centering diameter of 110 mm, letting the housing settle into precision pilot fits without additional sleeves. The integrated blocking brake supplies 22 Nm of static holding torque, so vertical or suspended axes stay in position during power loss. Position data are provided through Digital servo feedback (DSF), giving the controller rotor angle information at each sampling step. All power and sensor leads exit on the right side, and a factory-installed connector simplifies cable routing.

The unit ships with a plain shaft, allowing torque transfer through press-fit couplings, and a durable shaft seal helps block lubricant migration along the journal. A size code of 093 keeps the outer diameter consistent with other motors in the series, so legacy flange patterns remain unchanged when moving to this C-length version. This shaft arrangement also supports direct coupling to hubs or pulleys that rely on a smooth contact surface. Standard dynamic balancing limits residual vibration, and the normal housing construction supports general-purpose enclosures. The integrated brake and feedback features reduce the amount of external hardware required around the axis, which can help keep the motor installation compact in high-speed pick-and-place or indexing machinery.
