Product Description:

The MDD090B-N-040-N2M-130GB2 is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies controlled rotary power to automated axes that require coordinated, feedback-regulated motion. When paired with compatible drive electronics, the unit supports closed-loop velocity and position control so mechanical loads can accelerate, decelerate, and hold position accurately under changing duty cycles.

Mechanical interface dimensions start with a centering diameter of 130 mm, which aligns the motor frame to gearbox or flange seats without additional shims. The motor has a continuous standstill torque of 7.2 Nm, indicating the sustained load the rotor can support while locked without exceeding thermal limits. When driven at its nominal speed of 4000 rpm, the motor delivers rated power while maintaining synchronization between the stator field and rotor magnets. Cabling exits on side B, which can simplify routing where power and feedback share a single plug-in connector. Position data is returned as digital servo feedback (DSF) from the integrated multi-turn encoder, allowing the controller to correct small deviations in real time.

Dynamic holding requirements are addressed by a blocking brake that provides 11.0 Nm of torque to immobilize the shaft during power-off states. The drive side uses a plain shaft, and it is protected by a shaft seal to help keep lubricants in and contaminants out. Size code 090 corresponds to the stator diameter and helps guide selection of compatible mechanical couplings. The motor also has standard balancing for low residual vibration, a standard housing, a single-ended shaft on the drive face only, motor length code B, and connection through a circular industrial connector.
