Product Description:

The MDD041A-N-100-N2G-050MB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified for digital drive controllers, it has size 041 and a short A length code, which gives it a compact form for multi-axis assemblies where installation space is limited. Its standard housing encloses the stator and rotor and provides basic protection for use in industrial automation equipment that requires positioning or regulated motion. This type of motor is commonly used where accurate speed control and repeatable positioning are required from a compact servo axis.

The mechanical interface uses a centering pilot of 50 mm, allowing concentric seating against gearboxes or adapter plates. At standstill, the motor supplies 0.64 Nm of continuous torque, which is the continuous thermal limit for static holding or low-speed indexing. Dynamic operation is supported up to 10000 rpm, so the drive can carry out rapid positioning cycles. Power and feedback cables exit on side B, which can simplify routing when the shaft faces the load. The motor side connection uses a connector plug for quick connection during service. The motor also uses standard balancing to reduce radial forces on the bearings and limit structure-borne noise at higher speeds.

Position information is provided by resolver feedback mounted on the rotor, allowing analog position tracking with compatible controllers. The shaft uses a keyway for positive torque transfer to couplings or pulleys, and the design does not include a side B shaft end. The motor is supplied without a holding brake, so an external clamping method is required if the load must remain fixed when power is removed. The front bearing region is built without a shaft seal, which makes the motor better suited for clean, dry enclosures where oil splash or coolant ingress is not expected. That arrangement suits enclosed machines where the coupling area is protected from contamination.
