MDD041B-N-100-N2G-050MB1
The MDD041B-N-100-N2G-050MB1 is a brushless AC servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled three-phase current into precise rotary motion for positioning, indexing, or speed-regulated tasks in automated equipment. The B length code and 041 frame size place the unit at the compact end of the range, allowing installation in tight mechanical packages without extra support hardware. Its standard housing and balanced rotor help the motor fit small axes that still need stable alignment and repeatable motion.
A centering diameter of 50 mm provides the reference surface that locates the motor concentrically on the mounting pilot. Power and feedback leads exit on Side B, which helps keep connectors clear of moving parts in confined gantries or crowded machine frames. The motor can deliver a continuous standstill torque of 1.35 Nm, giving the axis holding force without relying only on the brake. For power-off retention, an integrated blocking brake provides 1.2 Nm of torque. When motion is commanded, the rotor reaches a nominal speed of 10000 rpm, supporting rapid cycle times in high-speed pick-and-place or spindle applications.
Position feedback is supplied by resolver feedback, providing rotor angle information for closed-loop current and velocity control. The shaft uses a keyway, allowing pulleys or rigid couplings to be mounted without slip during acceleration. Because the motor is delivered without a shaft seal, it is intended for clean, dry enclosures where lower friction is preferred over added sealing. Field wiring terminates through a removable connector, which supports orderly cable routing and consistent shielding continuity at the motor interface. Standard dynamic balancing keeps vibration low, and the single-ended shaft configuration avoids unnecessary overhang length in the driven assembly.
