Product Description:

The MDD090A-N-040-N2L-130GB2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated drive current into rotary motion for precision positioning tasks in industrial automation cells and machine tools. The motor size is 090, and the compact A-length housing helps it fit installations where mounting depth is limited. A standard housing and plain shaft layout support use in machine designs that require this mechanical format.

Mechanical interfacing uses a centering diameter of 130 mm. Power and feedback conductors exit on side B through a sealed connector, which helps keep cable routing orderly inside the machine. The integrated encoder sends position data as digital servo feedback, allowing the drive to manage commutation and monitor axis position during operation. Rated operation reaches a nominal speed of 4000 rpm, giving the motor a fast operating range for transfer, indexing, and positioning tasks. The plain shaft has no secondary shaft end, leaving the non-drive side available for the internal feedback package.

Continuous stall torque is 3.7 Nm, providing steady low-speed force for indexing and controlled holding during motion. A blocking brake rated at 11.0 Nm secures the load when power is removed, which is useful on vertical or stop-and-hold axes. The presence of a shaft seal helps maintain the IP65 enclosure protection at the shaft interface, while standard balancing reduces vibration during higher-speed movement. Internal Hall sensors support commutation with the drive, and the plain shaft geometry accepts common taper-clamp couplings. The shaft layout keeps the drive end simple for direct coupling to pulleys, pinions, or gear inputs that use a smooth-bore clamp.
