Product Description:

The MDD041C-N-100-N2K-050GA1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it serves as the rotating element in closed-loop motion axes where high accuracy and high speed are required. The 041 frame size with C length gives the motor a compact body that fits pick-and-place tools, electronic assembly equipment, and light conveyor sections where installation space is limited. It is suited for servo applications that require controlled acceleration, stable holding at low speed, and accurate position response from the feedback system.

Its continuous stall torque is 2.05 Nm, allowing the shaft to hold load at standstill without overheating during normal duty. A peak speed of 10,000 rpm supports rapid indexing, and a blocking brake rated at 1.2 Nm secures the axis when power is removed. The housing uses a 50 mm centering diameter for accurate alignment, and electrical power and feedback connections are routed through a sealed connector. The centering pilot helps position the motor accurately on the machine flange, which reduces alignment error between the motor and the driven mechanism. The rotor is balanced to the standard grade, which supports smooth operation in typical automation service.

All remaining interfaces are located on side A, which helps keep cable routing straightforward in compact cabinets and machine frames. Position sensing is provided by an integrated absolute encoder that supplies multi-turn data to the controller, while resolver feedback is also present as secondary feedback for commutation support. Mechanical output is delivered through a plain shaft with a shaft seal, allowing direct coupling to pulleys or rigid couplings while helping limit the entry of dust or coolant at the front end. Because there is no side-B shaft extension, the rear of the motor remains clear for the brake and feedback package.
