Product Description:

The MDD041A-N-100-N2K-050GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into controlled mechanical rotation for positioning and velocity tasks. Its compact format makes it suitable for smaller automation axes that need precise motion without a large motor envelope. In servo applications, the paired controller can adjust torque quickly as load conditions change to keep motion accurate.

The mechanical profile includes a continuous standstill torque of 0.64 Nm, which gives the axis holding capability for light stationary loads. Under rated excitation, the rotor can reach 10,000 rpm, making the motor suitable for high-speed motion in compact handling or spindle-type applications. The housing uses a centering diameter of 50 mm for accurate alignment at the mounting face, and the motor has size code 041 with length code A. The rotor is balanced to the standard grade to reduce transmitted vibration during operation. Mechanical output is transferred through a plain shaft, and a shaft seal is fitted at the output journal to help limit the entry of dust or coolant.

Position data are provided by an integrated absolute encoder, while speed control uses resolver feedback to support stable closed-loop operation. This feedback arrangement allows the drive to detect rotor position at startup and maintain consistent speed monitoring during motion. All power and signal leads are routed on Side B through a removable connector, which helps simplify cable routing in dense multi-axis layouts. The motor is supplied without a blocking brake, so any required holding function must be provided by the drive or by an external brake. The motor also uses a standard housing finish, and the single-ended shaft arrangement leaves no shaft extension on side B.
