MDD041C-N-100-N2G-050GB0
The MDD041C-N-100-N2G-050GB0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it is intended to deliver finely controlled torque and high rotational speed in compact automation axes, packaging stations, and electronic assembly lines. Its feedback arrangement allows the drive to coordinate position, velocity, and current loops closely with controller commands, which supports accurate starts, stops, and short indexing moves.
Mechanically, the motor follows a standard balancing grade to minimize residual vibration when coupled to precision gearheads. A centering collar diameter of 50 mm simplifies alignment with machine frames, and all power and feedback lines exit on side B, allowing cable routing away from the working envelope. A single industrial connector carries the phases, encoder signals, and protective ground in one plug, which keeps the interface compact. The drive end uses a plain shaft with a fitted shaft seal to help limit the entry of coolant or dust. The opposite end remains closed because there is no side-B shaft extension. Compact dimensions follow size code 041 and length code C, which suits installations where mounting space is limited.
During operation, the rotor can deliver a continuous standstill torque of 2.05 Nm, giving the axis enough holding force for light pick-and-place payloads without overheating. When velocity commands rise, the motor reaches a rated speed of 10000 rpm, which supports short-stroke indexing and high surface speed tooling. Position information returns to the drive through resolver feedback, enabling sinusoidal commutation under dynamic load changes. The design is supplied without a blocking brake, so any power-off holding requirement must be handled by external mechanics or by drive torque. Omitting the brake keeps rotor inertia lower and helps the axis respond quickly to acceleration and deceleration commands.
