MDD041C-N-100-N2G-050MA1
The MDD041C-N-100-N2G-050MA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed as an AC actuator for digital drive controllers in automated machinery, the unit converts commanded current into precise shaft rotation so that packaging stations, pick-and-place axes, and small spindle modules can achieve repeatable high-speed motion. Its compact housing and C length code help it fit installations where fast response and limited mounting space are both important.
The motor delivers a continuous standstill torque of 2.05 Nm, enabling stable holding or slow-speed feed without thermal overload. When fully excited, it can reach a nominal velocity of 10000 rpm, allowing rapid indexing where cycle time is critical. Mechanical alignment to adjoining framework is simplified by a centering shoulder with a diameter of 50 mm, and the rotor is ground to standard balancing quality to help keep vibration within normal servo limits. Power and feedback terminations are positioned on Side A of the stator housing and use a sealed connector, which supports straightforward cable routing while keeping the compact 041 frame free of obstructions.
A blocking brake is integrated to secure vertical loads during power loss, and it applies 1.2 Nm of static torque through a spring-applied mechanism that is released electrically when motion is commanded. Torque is transferred through a shaft with a keyway end, and the opposite side of the rotor is left blank to simplify coupling. Because the unit is supplied without a shaft seal, it should be installed where fluid ingress is not expected, or external sealing should be provided by the surrounding machine. Position feedback to the drive is generated through resolver feedback, giving rotor angle signals during rapid acceleration and completing the closed-loop control needed for accurate speed and position regulation.
