MDD041C-N-100-N2G-050MB1
The MDD041C-N-100-N2G-050MB1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides closed-loop rotary actuation for small-frame industrial axes that demand high speed and repeatability. An integrated blocking brake allows the rotor to remain fixed when power is removed, which is useful for vertical axes and controlled stopping tasks. This operating style supports repeatable starts, stops, and holding behavior when the motor is paired with a compatible digital servo controller. Its compact format suits assembly, packaging, and other automation equipment where accurate motion is needed in limited installation space.
During continuous stall conditions, the motor can deliver 2.05 Nm of torque, giving a solid reference for sizing the matching drive and transmission. A maximum rated speed of 10,000 rpm supports fast indexing or spindle duties where short cycle times are important. Power and feedback cables exit on side B of the housing, which helps keep cable routing consistent around the machine frame. The single-piece power and signal connector reduces wiring complexity because the motor uses one connection point instead of separate flying leads. The C-length stator increases the active stack height to reach the stated output without enlarging the flange outline.
The blocking brake generates 1.2 Nm of static holding torque, helping resist back-driving on light loads when the drive is disabled. A centering pilot of 50 mm aligns the flange accurately to machine plates and helps support concentric mounting. Position information is returned through resolver feedback, enabling robust sinusoidal commutation under high acceleration and changing load conditions. Motion is transferred through a splined shaft with a keyway, which supports secure torque transmission to pulleys or pinions. Because the shaft end is supplied without shaft seal, the motor is best used where liquid exposure at the output end is not expected.
