Product Description:
The MDD090B-N-040-N2L-110GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated drive current into precise rotary motion for positioning tables, pick-and-place axes, and packaging stations. Its electromagnetic design matches Indramat drive amplifiers, allowing direct integration into automated cells that require repeatable speed and position control. This arrangement supports accurate motion in systems where stable servo response and compact motor packaging are both important.
The motor uses a 110 mm locating pilot at the flange for accurate centering on the machine interface. Electrical terminations are arranged on Side B, and the unit uses a keyed connector for the power and feedback interface. At standstill, the stator delivers 7.2 Nm of continuous torque, and the nominal shaft speed is 4000 rpm during normal operation. A shaft seal is fitted at the output end to help limit the entry of oil or coolant, and the shaft arrangement uses the standard single-ended layout used on this motor style.
A blocking brake is installed and provides 11.0 Nm of static holding torque when the axis must remain in place after power is removed. Position information is returned through digital servo feedback (DSF), so the drive receives rotor data without the need for a separate external encoder assembly. The output interface is a plain shaft, which supports direct coupling to suitable transmission components. The motor has a frame size of 090 and a B length, giving it a mid-length housing that fits many servo-axis layouts while keeping the overall package compact. Standard housing construction is used across the body, providing the protection and form expected for multi-axis industrial installations.
