Product Description:

The MDD041B-N-100-N2G-050GB0 is a compact AC servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed for use with digital drive controllers. In automated assembly, packaging, and material-handling lines, it converts finely modulated inverter current into precise rotor movement for tooling stations, pick-and-place modules, and other high-speed axes. This operating role supports accurate starts, stops, and rapid direction changes during repetitive motion sequences.

Its continuous stall torque is 1.35 Nm, meaning the rotor can hold this torque indefinitely without exceeding thermal limits when cooled by natural convection. The design reaches a nominal speed of 10,000 rpm, enabling spindle-level rotation for short cycle times. A centering flange diameter of 50 mm aligns the housing precisely on machine frames, while standard dynamic balancing helps reduce vibration across the speed range. Power and feedback conductors exit on side B, and the connector arrangement keeps cable routing compact. Position data is supplied through resolver feedback, giving analog angular information that remains accurate despite electrical noise.

The form factor tagged size 041 uses the standard housing for this motor platform. A plain shaft transmits torque to the driven load, and the working-side shaft end remains active while the opposite end stays closed. The motor is built with a shaft seal, which helps keep coolant or dust away from the bearing cavity during sustained high-speed operation. Because the unit is supplied without a blocking brake, holding force must come from the drive or an external latch when the axis is stopped. Length code B identifies a short body style that helps save installation space, and the absence of a brake helps keep rotating inertia low for rapid reciprocating motion.
