Product Description:

The MDD041C-N-100-N2G-050GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts controlled current into precise rotary motion for indexing tables, pick-and-place arms, and other fast-cycle automation axes. A standard housing, balanced rotor, and connector interface simplify installation. The integrated blocking brake holds the load whenever the drive is disabled, which helps prevent unintended movement in vertical or other load-sensitive orientations. This type of motor is commonly used where short cycle times and accurate stopping are required across repeated motion sequences.

The motor delivers a continuous standstill torque of 2.05 Nm, so it can maintain static loads without exceeding thermal limits during closed-loop holding modes. When commanded to rated velocity, it can reach 10000 rpm, which supports rapid point-to-point moves in light inertial systems. The speed capability also gives the connected drive more flexibility when gear ratios are selected for small rotary axes. For emergency stopping or vertical axes, the integrated brake provides 1.2 Nm of holding torque that keeps the shaft locked after power loss. Mechanical mounting uses a centering diameter of 50 mm, which helps keep alignment accurate with flanges or compact transmission elements. Power and feedback cables exit on the A-side, which can simplify routing in installations where the cable set must stay clear of adjacent machine members.

Closed-loop accuracy depends on the built-in resolver feedback, which returns rotor position information and remains stable in high-vibration environments. Resolver-based sensing also supports stable commutation and smooth low-speed operation with a compatible controller. The motor uses a plain shaft, so couplings or pulleys can be fitted without a keyway, and the front end is fitted with a shaft seal to reduce contaminant entry. Length designation C indicates the active stack depth in the 041 frame. This motor length balances thermal mass and package size, allowing the unit to fit into compact axis layouts while maintaining the rated continuous torque.
