Product Description:

The MDD090C-N-040-N2L-130GL0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into rotational motion for positioning and velocity tasks in automated machinery. The model uses a standard housing and standard rotor balancing, allowing direct installation in enclosed cabinets. A removable connector handles power and feedback lines, simplifying service exchanges on production lines.

At standstill, the motor delivers 10.4 Nm of continuous torque, providing enough holding force for medium-load axes while the controller commands zero speed. During operation, it can reach a nominal speed of 4000 rpm, a value that matches high-frequency machining or indexing cycles. Position data are reported through the integrated digital servo feedback (DSF) interface, allowing the drive to close its control loop without external encoders. Mechanical centering is assisted by a 130 mm centering diameter that aligns the flange with the machine frame. All terminals are oriented to the left, so cabinet layouts must reserve clearance on that side for the single plug-in connector. Fluid ingress is mitigated by a shaft seal that blocks contaminants at the output shaft.

The length code C gives this 090-frame motor an extended stator stack for higher torque density without altering the mounting pattern. Frame designation 090 indicates the outside diameter, keeping compatibility with other motors in the series that share the same bolt circle. A plain shaft transmits torque directly to couplings, and the shaft end is supplied without a side-B extension to save space on the non-drive end. The unit is delivered without a blocking brake, so position retention during power loss must be handled by the drive or external mechanics. Standard housing and rotor balancing help limit vibration.
