Product Description:

The MDD090C-N-040-N2L-130PL2 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is built for digital drive controllers, where it converts commanded current into mechanical rotation for axes that must start, stop, and reverse rapidly in industrial automation. The unit combines standard rotor balancing with a sealed housing for direct mounting inside machine enclosures.

Its continuous stall capability is rated at 10.4 Nm, allowing the shaft to hold load torque without overheating during static positioning. When operated at nominal electrical frequency, the rotor can reach a top speed of 4000 rpm, which suits high-speed pick-and-place or spindle duties. An integrated blocking brake applies 11.0 Nm of holding torque to secure vertical axes when power is removed. Position and velocity are fed back to the controller through digital servo feedback (DSF), ensuring closed-loop accuracy over the full speed range. The motor flange carries a centering recess of 130 mm, and this diameter aligns the stator concentrically with the machine frame while respecting ISO mounting tolerances. Standard dynamic balancing minimizes residual vibration at all speeds and helps preserve bearing life.

All power and feedback conductors exit on the left side through a keyed circular connector, which simplifies cable routing in multi-axis assemblies. The shaft is machined with a keyway so pulleys or couplings can be locked axially without relying only on friction fits. A lip-type seal is installed at the output face to help prevent coolant or emulsions from entering the front bearing, which supports use in spray environments. The motor has a frame designation of 090, which corresponds to the stator diameter, and length code C extends the active core for higher power density without changing the mounting footprint. The shaft end is provided only on the drive side to accommodate close-coupled gear stages.
