Product Description:

The MDD090A-N-030-N2L-110GA2 is a synchronous AC motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Rated for use with digital drive controllers, it serves as the mechanical actuator in closed-loop positioning, conveying, and tool-handling stations where precise velocity and torque are commanded electronically. Its construction allows direct coupling to servo drives, turning controlled current into repeatable rotary motion in industrial automation cells. This arrangement supports accurate motion control in systems that require consistent response during indexing, transfer, and continuous-running tasks.

In continuous duty, the motor sustains 3.7 Nm of torque at standstill and accelerates up to the nominal speed of 3000 rpm without exceeding thermal limits. A built-in blocking brake applies 11.0 Nm to hold position during power loss, while the encoder provides digital servo feedback (DSF) so the drive can close the control loop. The 110 mm centering pilot keeps the shaft accurately aligned with mating components, which helps support stable coupling to gearboxes or mounting flanges. Power, brake, and feedback conductors exit on Side A through a sealed connector, giving the motor a single-plug connection layout.

Standard rotor balancing helps keep vibration within ISO grade R during operation. The motor uses a single shaft end, and the output is a plain shaft with a shaft seal that helps limit lubricant migration and entry of fine dust. Its frame size is 090 and the housing length is A, which place it in the compact range of this motor family while preserving the stiffness needed for precise motion. The standard housing uses convection cooling, so the unit operates without a separate fan assembly. This cooling method keeps the exterior design simple and supports installation where external airflow hardware is not preferred.
