Product Description:

The MDD090B-N-020-N2L-130PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers in automated machinery. It belongs to the MDD Synchronous Motors series. With its size 090 frame, it serves as an electromechanical actuator that converts drive current into controlled rotary motion for positioning and velocity-regulated tasks on production lines.

The stator flange provides a centering diameter of 130 mm, allowing precise alignment with gearboxes or mechanical adapters. Power and feedback conductors exit on the left side, which helps with cable routing in cabinets arranged for left-hand connections. The model uses a sealed connector rather than flying leads, so the electrical connection can be made without rewiring the cable ends. When energized but stationary, it can deliver a continuous torque of 7.2 Nm, which is the load it can support indefinitely without exceeding thermal limits under natural convection. During operation, the rotor reaches a nominal speed of 2000 rpm, which suits applications that need moderate speed with accurate electronic control. The housing is the standard non-ventilated type, so no external blower is required.

An integrated blocking brake supplies up to 6.5 Nm of holding torque, enabling axis locking when the drive is disabled or power is removed. Position accuracy is maintained through digital servo feedback (DSF), which returns high-resolution rotor data to the controller for closed-loop regulation. The shaft has a keyway for direct torque transfer to pulleys or couplings, and a factory-installed shaft seal helps prevent lubricant from entering the motor interior. Length code B indicates the medium body length, balancing thermal mass and overall size. The motor also has a standard single-ended shaft and a conventional connector-type power interface for installation in multi-axis assemblies.
