Product Description:

The MDD041B-N-100-N2G-050MA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat. It is intended for use with digital drive controllers, where it converts current-controlled commands into precise rotary motion for positioning axes, pick-and-place heads, and small spindle stations in industrial automation. The compact 041 frame and B length make it suitable for installations where available space is limited. It can be mounted directly to a machine plate or bracket, which helps keep the drive train short and rigid. Its standard rotor balancing supports stable operation in tightly packed machine layouts.

Under rated conditions, the rotor reaches a nominal speed of 10,000 rpm, which supports fast cycles and short move times on light servo axes. At standstill, it can deliver 1.35 Nm of continuous torque, helping the motor maintain accurate low-speed motion without excessive heat buildup. The pairing of high nominal speed and usable standstill torque fits both rapid indexing and precise settling. Mechanical alignment is aided by a centering diameter of 50 mm, which helps seat the motor accurately in the mating mount. Power enters through a plug-in connector, while position data is supplied by integrated resolver feedback for closed-loop control. This arrangement lets the drive monitor rotor position continuously during acceleration, deceleration, and steady-speed operation.

Field wiring approaches the motor from side A, which can simplify cable routing in compact enclosures and narrow machine frames. The output uses a keyway shaft for common torque-transmitting couplings, and there is no secondary shaft on side B. Because the motor comes without a blocking brake, the axis must rely on external holding force or maintained drive torque when power is removed. The design also omits a shaft seal, so the installation area should stay free of pressurized coolant or oil.
