Product Description:

The MDD090B-N-020-N2L-130PB2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it turns commanded current into tightly regulated rotary motion used in automated tooling stations, pick-and-place axes, and other factory tasks where precise positioning is essential. Its mechanical outline and electrical interface fit modular drive platforms used in many industrial automation cells. This makes it suitable for repeatable starts, stops, and speed changes under closed-loop control.

Its centering pilot measures 130 mm, providing a rigid reference surface for flange mounting. Power and feedback cables exit on side B, so control cabinets can be arranged with fixed conduit paths on the same face. The unit produces 7.2 Nm of continuous torque at standstill, and standard rotor balancing keeps vibration low during slow indexing moves. Position is reported through digital servo feedback (DSF), allowing the drive to close the velocity and position loops accurately. The motor has a nominal speed of 2000 rpm when the standard housing is cooled by ambient air.

During deceleration or vertical holding, the brake supplies 11.0 Nm of static torque, preventing axis drift once power is removed. Electrical terminations are made through a single connector, which helps preserve the enclosure seal. The motor also includes a standard shaft seal to help limit oil ingress. The stator uses Motor Size 090, a diameter class that balances torque density with compact mass. Its output shaft is machined with a keyway and is present only on the drive side, while the opposite end remains blind. That arrangement supports direct coupling while keeping the non-drive end free of an external shaft extension.
