MDD041B-N-100-N2K-050FA1
The MDD041B-N-100-N2K-050FA1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers and converts regulated current into rapid, repeatable rotary motion for demanding positioning profiles in automated assembly equipment, light conveyor zones, and laboratory handling systems. Its synchronous design supports accurate speed and position response when paired with a compatible control system. The compact housing helps reduce footprint in multi-axis installations with limited enclosure depth, and the motor remains suitable for layouts where available mounting space is restricted.
Under continuous load, the motor delivers 1.35 Nm of torque while maintaining thermal equilibrium at the stator laminations. High-speed applications are supported by a nominal velocity of 10000 rpm, enabling fast indexing and short cycle times on lightly loaded axes. A blocking brake rated at 1.2 Nm holds the axis when power is removed, helping prevent back-driving on vertical slides or other gravity-affected mechanisms. Electrical and feedback connectors are arranged on side A, so cabling exits in a consistent direction around neighboring components. A centering diameter of 50 mm aligns the flange with the machine interface and supports accurate mounting.
Feedback is handled through resolver feedback, complemented by an integrated absolute encoder that provides multi-turn position information to the drive. This combination supports stable rotor-angle tracking during operation and preserves position reference through repeated stop and start sequences. The motor uses a plain shaft, and there is no shaft seal, so the installation area should be kept free of coolant splash or oil mist. The length code B indicates a longer rotor stack within the compact 041 frame size, which helps add inertia for smoother speed regulation. The shaft end is provided only on the drive side, and the motor uses a standard housing with standard balancing.
