Product Description:

The MDD090B-N-040-N2L-110PL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, it delivers controlled torque and speed for positioning, indexing, and continuous motion on industrial machinery. An integrated blocking brake and onboard feedback simplify installation, while the standard housing and balancing profile allow the motor to mount directly into machine frames without additional vibration isolation. Its primary role is to translate regulated AC drive output into mechanical rotation for axes used in packaging lines, pick-and-place gantries, and light machine tools.

Rated for a nominal speed of 4000 rpm, the rotor can follow rapid command changes from the drive without exceeding its magnetic limits. Continuous output at standstill reaches 7.2 Nm, so static loads can be held without overheating. When power is removed, the integrated blocking brake provides 11.0 Nm of retention torque to secure the axis. Motor feedback is handled through digital servo feedback (DSF), giving the controller high-resolution position data. Power and encoder conductors plug into a single connector, and the wiring exits the motor on the left side to suit layouts that route cable trays in that direction.

For mechanical alignment, the front flange carries a centering diameter of 110 mm, which mates with standard Rexroth mounting pilot holes. The shaft is machined with a keyway and sealed by an integral shaft seal to limit lubricant migration into the stator. Frame size 090 and length code B set the overall envelope, while the standard shaft end omits a side-B extension to reduce overhung mass. Standard dynamic balancing keeps residual vibration low in high-speed applications, and the molded housing channels airflow around the stator to remove heat generated during continuous duty cycles.
