Product Description:

The MDD041B-N-100-N2G-050FB1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, this motor supplies closed-loop rotary motion for precise positioning on automated assembly lines, light gantries, and spindle drives where space is limited and high rotational speed is required. Its compact layout suits axes that need quick response without adding much mass to the moving assembly. This makes it a practical choice for compact motion modules that still require repeatable servo performance.

The unit delivers a continuous standstill torque of 1.35 Nm, giving the drive enough static holding capacity for small payloads without excessive current draw. During motion, it can reach a nominal speed of 10,000 rpm, which suits high-cycle pick-and-place operation and other fast indexing tasks. Mechanical alignment is supported by a centering diameter of 50 mm, while standard balancing helps limit vibration at full speed. Power and feedback conductors exit on side B through a single connector, which helps simplify cable routing in compact machine layouts. The housing uses a standard convection-cooled design, and the compact frame helps keep moving mass low on fast axes.

Additional features support secure stops and accurate feedback during axis control. A blocking brake supplies 1.2 Nm of holding torque to help prevent axis drift when power is removed. Rotor position is monitored by resolver feedback, which helps the drive maintain commutation in electrically noisy environments. The output is a plain shaft on the A-side only, with no secondary shaft end. The motor is supplied without a shaft seal, so it is best used in clean, dry installation areas where contaminants are not expected to reach the shaft opening.
