Product Description:

The MDD090B-N-040-N2M-110GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into precise rotary motion for automated machinery such as packaging lines, transfer systems, and small machining centers. The combination of an integrated multiturn encoder and an internal blocking brake lets the axis keep its absolute position when power is removed, helping prevent drop or drift in vertically mounted stages. Its plain shaft transmits torque directly to couplings or pulleys.

At standstill, the motor delivers a continuous torque of 7.2 Nm, enabling stable holding force without exceeding the thermal limits of the B-length stator package. When energized by a matched drive, it can reach a nominal speed of 4000 rpm, giving a broad constant-power range for rapid indexing moves. Accurate centering against gearboxes or mounting flanges is assisted by a 110 mm centering diameter that aligns the housing concentrically. Power, brake, and feedback leads exit on the left side, and a keyed connector simplifies cable attachment. Standard dynamic balancing and a standard housing help limit vibration and support heat dissipation while keeping overall mass low.

The integrated blocking brake produces 11.0 Nm of static torque to lock the rotor during power interruptions, and the brake is supplied prewired through the main connector. Position feedback combines an integrated multiturn absolute encoder with digital servo feedback (DSF), so the controller receives both absolute angle and high-resolution incremental data. A plain shaft with a factory-installed shaft seal helps prevent lubricant migration while limiting the ingress of dust and fluid. The 090 frame size and B-length code match the series dimensions, and the single-ended shaft design without a side B extension simplifies coupling selection for tight installations.
