Product Description:

The MDD090A-N-030-N2M-130PA2 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical energy from the drive into rotary motion that can be accurately commanded in industrial automation cells, packaging lines, and material-handling axes. The integrated multiturn absolute encoder supplies repeatable position data to the controller. Its compact frame with standardized mounting dimensions supports installation in modular machines and helps maintain consistent alignment during assembly.

At standstill, the rotor can apply a continuous torque of 3.7 Nm, which is the maximum load it can hold without overheating during static positioning tasks. Once energized, the motor reaches a nominal speed of 3000 rpm, allowing direct coupling to gearboxes or belt drives that require a high base speed. Mechanical centering on a 130 mm pilot diameter keeps the motor aligned with the driven assembly and helps limit runout. A blocking brake integrated on the B-side delivers 11.0 Nm of holding torque, preventing shaft rotation when power is removed on vertical or suspended axes. Command and feedback loops are closed through digital servo feedback, allowing the drive to read absolute position without incremental homing.

Power and encoder leads exit on Side A, so panels can be wired from one direction and service space remains predictable. The motor uses a single locking connector, reducing assembly complexity compared with hard-wired cable glands. Torque is transmitted through a keyway, which matches common pulley and coupling hubs and helps prevent slip under cyclic loading. The rotor uses standard balancing, which supports direct coupling without additional correction weights while keeping vibration suitable for precision motion systems. This arrangement is useful in applications with repeated starts, stops, and load changes, where stable shaft alignment and consistent feedback are important for smooth motion.
