Product Description:

The MDD090B-N-020-N2M-130PL2 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is an AC permanent-magnet servo motor intended for use with compatible digital drive controllers so that torque and velocity loops can be closed in real time. In automated machinery, the unit supplies direct rotary motion to indexing tables, gantry axes, and packaging stations where accurate positioning and rapid reversals are required. Its servo design also supports repeatable motion in applications that must respond quickly to load changes during continuous production.

The mechanical interface includes a centering diameter of 130 mm, allowing the housing to seat concentrically against gearbox flanges. Standard dynamic balancing helps limit vibration during speed changes, and power and feedback leads exit the motor on the left side through a single industrial connector. At stall, the electromagnetic design delivers 7.2 Nm continuously without auxiliary cooling, and the laminated core supports routine operation up to 2000 rpm. This arrangement supports stable running in reversing duty, while a hardened shaft with a keyway transmits torque to pulleys or pinions without slip under cyclic loads.

Static load security is handled by a spring-applied brake that develops 11.0 Nm of holding torque when the control cabinet is de-energized. Command accuracy is improved by the feedback channel, which uses Digital servo feedback (DSF) signaling so the drive receives high-resolution position data during operation. The motor is identified inside the series by size code 090 and length code B, which provide a compact frame with room for the brake and feedback electronics. A shaft seal is fitted to help limit dust or coolant ingress, and the standard housing finish suits typical industrial installations without additional protective covers.
