MDD041A-N-100-N2G-050PB1
The MDD041A-N-100-N2G-050PB1 is a permanent-magnet AC servo motor built by Bosch Rexroth Indramat for integration with digital drive controllers in the MDD Synchronous Motors series. It acts as the rotary actuator in compact automation stations, converting commanded current into angular motion that can be synchronized with position loops inside the drive. The 041 frame size and A length code keep overall mass low, making the unit suitable for lightweight pick-and-place heads and high-speed spindles that demand fast acceleration in packaging, handling, and light machining equipment while keeping the housing compact for densely packed machine assemblies.
This model delivers a continuous standstill torque of 0.64 Nm, which is the base mechanical output available without forced cooling. During operation, it can reach a rated speed of 10000 rpm, so high-cycle workpieces can be indexed quickly while remaining under servo control. A built-in blocking brake supplies 1.2 Nm of static holding torque, letting vertical axes maintain position when system power is down. Rotor position is monitored through resolver feedback, providing sine-cosine signal pairs that remain stable across the full speed range and resist electrical noise. The stator housing seats against a pilot with a 50 mm centering diameter, giving a fixed reference for coaxial alignment to gearboxes or flange plates.
The motor uses standard balancing, so vibration levels stay within ISO limits at maximum speed without extra tuning. Power and feedback connectors are oriented on side B, keeping cables clear of the driven shaft and simplifying routing in multi-axis assemblies with limited cable space. The output shaft uses a keyway profile that accepts common taper keys for slip-free torque transfer, and a shaft seal protects the front bearing against splash and fine dust. The motor also has a connector-style terminal block, a standard housing, and a single-ended shaft for compact installations where controller space and cable clearance are limited.
