Product Description:

The MDD090A-N-040-N2M-130GR2 synchronous servo motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for connection to digital drive controllers, it serves as an electromechanical actuator that converts regulated current into tightly governed torque and speed. By integrating into multi-axis packaging lines, pick-and-place systems, or light machining stations, the motor provides closed-loop rotary motion that can be commanded, monitored, and coordinated with other axes through the associated drive electronics. This type of motor is commonly used where the drive must maintain accurate position and speed under changing load conditions.

At the mechanical interface, a centering diameter of 130 mm aligns the flange to mounting fixtures, and a right-side power and feedback port implemented with a connector simplifies cabinet wiring. Standard rotor balancing keeps vibration within design limits for frame size 090. When energized, the motor can deliver a continuous stall torque of 3.7 Nm while maintaining regulated output speeds up to 4000 rpm. An integrated multi-turn absolute encoder supplies digital servo feedback, allowing the controller to detect position immediately after power restoration. The standard housing encloses the windings against ambient contaminants, and the short A length code reduces axial footprint.

Positional stability during shutdown is provided by a blocking brake that secures the rotor with 11.0 Nm of holding torque. The transmission end uses a plain shaft, and its journal area is protected by a shaft seal to limit oil migration and dust ingress. Because no side-B shaft end is present, couplings or pulleys mount only on the drive side, easing guarding in tight machines. This single-ended layout keeps the non-drive end clear for compact machine installation.
