Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-030-N2L-130GA2 synchronous motor as part of the MDD Synchronous Motors series. This motor is intended for mounting to digital drive controllers, where its electronically commutated design delivers controlled torque and speed for indexing tables, packaging machinery, and other repetitive motion tasks in industrial automation. The unit belongs to the motor-for-digital-drive-controllers category, so it serves as the rotating actuator while the external drive regulates current and position loops. Its operating role makes it suitable for axes that require repeatable motion and stable closed-loop control during frequent starts and stops.

The mechanical interface uses a 130 mm centering diameter that aligns the flange with the driven equipment, and standard balancing helps limit vibration across the rated operating range. Power and feedback leads exit on Side A, and the factory-installed connector simplifies cable routing while maintaining the housing’s standard ingress protection. Inside, a resolver emulator provides Digital servo feedback (DSF), so the drive receives position data each cycle for closed-loop operation. During prolonged hold states, the motor can deliver 3.7 Nm of continuous torque at standstill, and when energized the stator supports operation up to 3000 rpm without exceeding thermal limits. A shaft seal helps keep coolant and dust out of the bearing area, and the plain housing requires no external cooling devices.

A blocking brake clamps the rotor with 11.0 Nm of static torque whenever control power is removed, which helps prevent unintended axis drift on vertical loads. The device uses Motor Size 090 with Motor Length Code A, a combination that keeps the motor compact while still accommodating the winding set. A plain shaft with a standard single-ended configuration transmits torque directly, and the side-B extension is omitted to save space in tight installations. The brake is especially useful where the load must remain stationary after shutdown.
