Product Description:

The MDD090A-N-040-N2M-130GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for integration with digital drive controllers, it converts regulated three-phase electrical power into precise mechanical rotation. The motor is used on compact processing stations, labeling heads, and small gantries where accurate positioning, fast indexing, and repeatable velocity profiles help maintain cycle time and consistent product handling in automated production lines. Its compact format also suits machines with limited mounting space.

Mechanically, the motor aligns to the machine plate through a centering pilot of 130 mm and uses standard dynamic balancing to keep vibration low at rated speed. The winding can deliver a continuous standstill torque of 3.7 Nm, while the rotor can reach 4000 rpm when the drive supplies the rated voltage and frequency. A blocking brake on the B-side provides 6.5 Nm of static holding torque after power is removed. All power and feedback conductors exit on the right side, and connector-style terminals simplify cable routing. The motor has length code A within the 090 frame size.

The position loop is closed by the integrated multiturn absolute encoder, which transmits rotation and turn-count data through the digital servo feedback (DSF) interface. This arrangement gives the controller absolute position information after power-up and supports applications that need retained position data during normal operation. A sealed housing and the included shaft seal help keep contaminants away from the bearings during high-cycle duty. Motion is transferred through a plain shaft with no secondary extension on side B, which suits compact gearheads or belt pulleys. The motor is intended for digital drive controllers and uses electronic commutation instead of analog tacho feedback.
