MDD041A-N-100-N2G-050MB0
The MDD041A-N-100-N2G-050MB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for direct coupling to digital drive controllers in automated machinery, where it converts commanded current into precise angular motion. The motor belongs to a compact size line and uses permanent-magnet excitation to deliver rapid acceleration and repeatable positioning in pick-and-place units, packaging stations, and small transfer axes. Its synchronous design also supports stable speed and position control during frequent start-stop motion.
The motor combines key electrical and mechanical features for use with a matching drive. The nominal rotor speed reaches 10000 rpm, allowing short cycle times in light-duty servo stages. At standstill, it can maintain a continuous torque of 0.64 Nm, so a held load remains stable without overheating. Mounting alignment is assisted by a centering diameter of 50 mm, and the stator housing uses standard balance grading to help limit vibration. Power and feedback leads exit on side B, and the signal set is routed through a factory-installed connector. This cable orientation helps preserve bending clearance around nearby axes and supports compact machine layouts.
The unit is supplied without a blocking brake, so external clamping or drive torque must secure vertical loads when power is removed. Position data is returned through resolver feedback, which provides rotor angle information to the controller across the speed range. The single-ended shaft uses a keyway to transmit torque to couplings, and no shaft seal is fitted, making the motor suitable for clean, dry enclosures. With motor size 041 and length code A, the frame remains light enough for small gantry axes while still using standard flange patterns.
