Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-020-N2M-130GL1, a servo motor in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated electrical power into rotary motion for axes that require coordinated position and velocity control in automated assembly and machining lines. The motor uses a standard housing, has standard dynamic balancing to reduce vibration, and follows the B length code for its overall body depth.

Under steady-state load, the motor provides a continuous standstill torque of 7.2 Nm, which is suitable for holding a load during dwell periods without overheating. Its rated speed is 2000 rpm, allowing the axis to support slow or moderately fast cycles with a stable magnetic field pattern. A centering diameter of 130 mm aligns the flange with gearboxes and machine plates for accurate mounting. The integrated blocking brake supplies 6.5 Nm of holding torque, so a vertical axis can remain locked when power is removed. Power is transmitted through a plain shaft, and a shaft seal is fitted to help keep contamination out of the front bearing. An integrated multiturn absolute encoder reports rotor position after power loss, which removes the need for a separate homing routine.

All electrical terminations exit on the left side through a keyed connector, which helps keep cable routing orderly when the motor is mounted in compact machine spaces. Position and speed signals are returned through digital servo feedback (DSF), matching the signal format used by compatible Indramat drive controllers. The motor is built in size code 090, which gives it a compact frame for multi-axis layouts. A standard shaft end is provided only on side A, and the built-in shaft seal supports IP-rated enclosures by helping limit oil mist migration.
