Product Description:

The MDD093D-N-040-N2L-110PR1 is a synchronous servo unit manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts pulse-width-modulated current from the inverter into mechanical rotation for coordinated multi-axis machinery. The motor uses standard mechanical balancing and a keyed output shaft, so it can be coupled directly to gearboxes, timing pulleys, or load shafts in industrial automation equipment that requires accurate closed-loop speed regulation.

The motor delivers a continuous standstill torque of 24.0 Nm, allowing it to hold loads without overheating when motion is paused. Under rated winding excitation, it reaches a nominal speed of 4000 rpm, giving a wide velocity range for positioning and process drives. A centering diameter of 110 mm aligns the flange precisely to mating machine frames, while frame size 093 sets the outer stator dimensions and mounting hole pattern. Rotor position data are returned to the controller through digital servo feedback (DSF), which supports high-resolution velocity loops and rapid disturbance rejection. Power and signal terminations are made through a single plug-in connector, which helps simplify wiring.

The motor includes a holding brake with 11 Nm of static torque, so the shaft can be locked during power loss or emergency stops. All service ports are located on the right side of the housing, which suits layouts where cables enter from one side of the cabinet. The motor uses length code D, which is the longest rotor stack offered in this frame. A shaft seal helps protect the internal bearings from coolant spray and airborne oil. The output uses a single-sided keyed shaft, and the motor has standard housing construction with controlled rotor mass distribution to help maintain low vibration during operation.
