Product Description:

The MDD090A-N-020-N2L-110GA0 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical input into precise rotary motion for positioning axes and feed drives in industrial automation. The model is supplied without a blocking brake, so external mechanical retention or drive torque must hold the load during power-off conditions. This arrangement is commonly used on axes where holding force is provided elsewhere in the machine design rather than by the motor itself.

The motor’s mechanical envelope includes a centering diameter of 110 mm, allowing repeatable alignment inside a gearhead or machine frame. At standstill, it delivers 3.7 Nm of continuous torque, which supports stable operation under sustained load. During operation, the rotor reaches a nominal speed of 2000 rpm, matching applications that need moderate velocity with high positioning accuracy. Motion feedback is handled through digital servo feedback (DSF), enabling closed-loop current and position control from the associated drive. Connections leave the housing on Side A, which helps keep cable routing consistent in compact machine layouts. Dynamic balance and housing execution are standard, so the motor fits typical installation requirements without special mechanical adaptations.

Plug-in power and encoder terminations use a compact connector, allowing straightforward connection to the matching drive and feedback cables. The motor has frame size 090 and length code A, which indicate a compact housing depth for this product range. A shaft seal is integrated at the drive end to help limit particle ingress when the motor is coupled to adjacent equipment. The output uses a plain shaft in a single-ended configuration, so torque is transferred through the selected external coupling. This layout supports direct integration with common machine transmissions while keeping the mechanical interface simple and easy to match with standard mounting hardware.
