MDD041B-N-100-N2G-050PA0
The MDD041B-N-100-N2G-050PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts precise current commands into mechanical motion for compact industrial axes that require high rotational speed and consistent positioning accuracy. Its compact format suits small automation modules where installation space is limited. The motor is also well suited to applications with frequent start-stop motion and repeatable positioning demands.
At a nominal speed of 10,000 rpm, the rotor can sustain rapid indexing cycles demanded by electronic assembly lines and miniature handling systems. At standstill, the motor delivers a continuous torque of 1.35 Nm, giving the axis enough holding force for fine positioning without thermal overload. A centering diameter of 50 mm aligns the stator flange precisely against the mounting pilot and helps maintain concentricity between the motor and driven mechanics. All power and feedback conductors exit on the A-side, reducing cable loops inside compact cabinets, and the single-piece connector allows quick exchange while preserving EMC shielding. Because the model is supplied without a blocking brake, external locking or drive torque must hold the load stationary when power is interrupted.
The motor’s closed-loop accuracy is supported by integrated resolver feedback, which returns electrical angle data for real-time current vector control. A shaft machined with a keyway secures hubs, gears, or pulleys against torsional slip, and the fitted shaft seal helps prevent coolant or dust from migrating along the shaft into the stator cavity. Frame size 041 corresponds to a 41 mm square section that minimizes footprint while still accommodating the B-length stator stack and standard housing. Standard dynamic balancing keeps vibration within ISO limits at high speed, and the absence of a side-B shaft end simplifies coupling alignment in tight multi-axis assemblies.
