Product Description:

The MDD041C-N-100-N2K-050FB0 is a compact servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. The model is intended for direct coupling to digital drive controllers, where its small frame and high rotor velocity support precise positioning in pick-and-place stations, light gantries, and semiconductor tools. By combining position feedback with a plain output shaft, the motor converts commanded current into regulated rotary motion. Its compact housing also suits machines that need short cable runs and limited installation space around the axis.

The motor can supply a continuous standstill torque of 2.05 Nm, allowing it to hold a load without external gearing when power is applied. During dynamic cycles, it can reach a rated mechanical speed of 10000 rpm, so it fits installations that demand rapid acceleration and short indexing times. A centering diameter of 50 mm aligns the stator flange to the machine frame, simplifying coaxial assembly and minimizing eccentricity. All power and feedback conductors exit on Side B of the housing, which helps keep cable routing clear of moving machine elements. Position feedback is delivered through resolver feedback; this analog feedback device provides rotor angle signals per revolution and tolerates thermal and vibration stress better than many optical systems.

The rotor is balanced to the Standard quality class to help limit vibration during high-speed operation. The motor also includes an integrated absolute encoder for retained position information, and machine wiring is handled through a sealed connector interface. A plain shaft with no keyway supports clamping hubs used on precision axes. The absence of a blocking brake and shaft seal keeps rotating mass and friction low, which is useful in clean installations or systems that rely on external holding devices.
