Product Description:

The MDD090C-N-020-N2L-130PA2 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in automated machinery. It belongs to the MDD Synchronous Motors series and is intended to deliver position-controlled rotary motion in assembly lines, material-handling stations, and similar closed-loop applications. The model combines a standard housing and balancing approach with a keyed shaft to transfer torque into couplings or gear stages.

The centering diameter is 130 mm, a dimension that aligns the motor accurately against the machine mounting face and keeps runout low. Position and velocity signals are provided through digital servo feedback (DSF), letting the controller close high-resolution loops without external encoders. At standstill, the electromagnetic system can generate 10.4 Nm of continuous torque, so feeding mechanisms can hold load without overheating. During emergency stops, the integrated blocking brake applies 11.0 Nm of holding force to secure the axis when power is removed. Under rated conditions, the rotor reaches 2000 rpm, matching drive controllers that deliver corresponding stator frequencies for moderate-speed, high-torque duties.

All electrical terminations are arranged on side A, and the power and feedback wires plug into a single connector, which simplifies cabinet routing. The motor uses a keyway shaft, and a shaft seal blocks coolant or lubricants from migrating along the journal into the bearing cavity. Standard dynamic balancing minimizes vibration across the motor’s speed range, and the standard housing dissipates copper losses to ambient air. Because the rear shaft extension is omitted, axial space is saved and the load connection remains on the primary face only, which suits applications where torque is transferred from one side.
