Product Description:

The MDD090C-N-040-N2L-130GL2 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a permanent-magnet servo unit, it is designed for coupling to digital drive controllers so automated axes can receive fast torque responses and precise velocity regulation in assembly lines, handling modules, and similar industrial stations. This motor is suited for closed-loop motion tasks that require stable speed control and accurate positioning during repeated machine cycles.

This model uses standard dynamic balancing to limit bearing load and vibration during operation. A centering shoulder of 130 mm positions the housing concentrically against the machine plate, and a nominal speed rating of 4000 min⁻¹ indicates the top synchronous velocity that the controller may command. At standstill, the motor can deliver 10.4 Nm continuously without exceeding its thermal limits, providing steady holding force for indexing tables. Rotor position is reported through Digital servo feedback (DSF), enabling fine position loops in the drive. Power and feedback conductors leave on the left side through a keyed connector, which simplifies cabinet cable routing. The frame follows length code C, and the standard housing permits convection cooling without additional fins.

A blocking brake is integrated, and it secures the shaft with up to 11.0 Nm when power is removed so suspended or vertical loads remain stationary. The standard shaft end is a plain shaft without a secondary side-B extension, facilitating direct coupling to pinions or clamping hubs. A dedicated shaft seal surrounds the journal to limit oil or dust ingress at the mounting face. Motor size 090 gives the unit a compact profile while leaving room for the required winding space. The brake, shaft arrangement, and feedback system support use in automated equipment where consistent motion control and secure stopping are required.
