MDD041A-N-100-N2G-050MB1
The MDD041A-N-100-N2G-050MB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. With size code 041 and an A-length housing, the unit fits tightly packed multi-axis assemblies while still supporting the fast motion needed in electronic packaging and pick-and-place heads. Intended for digital drive controllers, it converts regulated three-phase current from a compatible Indramat drive into precise rotary motion for repeatable speed and position profiles in automated equipment. The rotor is dynamically balanced to the standard grade used for this frame, which helps reduce vibration transfer to nearby machine parts during rapid acceleration and stopping.
Its rated output speed reaches 10000 rpm, enabling short cycle times in indexing tables and small spindle applications. At standstill, the electromagnetic circuit sustains a continuous torque of 0.64 Nm without overheating, so light loads can remain held between moves. A spring-applied blocking brake has a torque rating of 1.2 Nm, which secures the shaft during power loss or an emergency stop. Accurate alignment is supported by a 50 mm centering diameter on the front flange, and power and feedback wiring are combined in a single connector that keeps the motor interface compact. This arrangement reduces the number of separate cable entry points and helps simplify routing in dense control cabinets.
For position feedback, the motor uses resolver feedback, delivering analog sine-cosine signals that the drive converts into real-time rotor angle data. This feedback method gives the controller continuous position information for stable speed regulation and accurate motion response across the operating range. Cables exit on side B, which helps keep the harness away from the driven load on the opposite face. The ground steel shaft includes a keyway so it can engage standard keyed couplings, and the motor is supplied without a shaft seal for clean, dry environments where lower seal friction is preferred.
