MDD041B-N-100-N2K-050MA0
The MDD041B-N-100-N2K-050MA0 is a compact AC synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts regulated inverter output into high-speed rotary motion for pick-and-place heads, small conveyors, and other dynamic axes in industrial automation. The frame follows the series standard housing, so it mounts directly with matching pilot diameters and bolt circles, providing consistent mechanical alignment across machines that share this platform.
This model delivers a continuous standstill torque of 1.35 Nm, giving dependable holding force during position control without overheating. Under rated excitation, the rotor reaches a nominal speed of 10000 rpm, allowing fast cycles in tight-tolerance processes. Power and feedback terminations are routed on Side A through a single connector, simplifying cable runs inside compact cabinets. Accurate location in the machine frame is aided by a 50 mm centering diameter, while standard balancing keeps residual vibration within limits expected for shaft-mounted encoders and couplings. Additional mechanical descriptors include motor size 041 and length code B, both indicating the stack height selected for this torque-to-speed profile.
The solid shaft uses a keyway to transmit torque to pulleys or gearsets, and the front end is supplied without a side B extension to conserve space. Position data originate from resolver feedback that works in parallel with the integrated absolute encoder, enabling both coarse commutation and fine multi-turn position reporting. For holding applications, the motor is shipped without a blocking brake, so external clamping devices must secure vertical loads. Because there is no shaft seal, the unit should be installed in dry zones or paired with a protected gearbox as needed.
