Product Description:

The MDD090C-N-030-N2M-130GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated electrical energy into controlled rotary motion for positioning and speed-control tasks in industrial automation cells, transfer lines, and material-handling axes. Because it is a synchronous design, rotor motion follows the controlled magnetic field generated by the paired drive, which helps maintain accurate speed and position under changing load. This makes the unit suitable for feed axes, rotary tables, and handling equipment that require repeatable motion.

This model develops a continuous standstill torque of 10.4 Nm, allowing it to hold load without active cooling while the shaft is stationary. At rated electrical conditions, it can reach a nominal speed of 3000 rpm, which suits many servo applications that need repeatable cycle timing and stable velocity control. Mechanical integration is aided by a centering shoulder diameter of 130 mm, which helps position the motor accurately against the mounting surface. The motor uses size 090 for the frame and length code C for the housing length, giving a compact format for machines that need moderate torque in limited space. The compact housing can be easier to fit into machine sections where surrounding guards, couplings, and adjacent modules leave little installation space.

A blocking brake is fitted and can apply up to 6.5 Nm of holding torque to secure vertical or suspended loads when power is removed. Feedback to the controller is provided by digital servo feedback working with an integrated multi-turn absolute encoder, which supplies position data for precise motion control and immediate position availability after startup. Power and signal conductors leave through connections on the right side by way of a sealed connector, which can simplify cable routing in left-to-right cabinet layouts. The motor has a plain shaft without a side-B extension and includes a shaft seal to help keep contaminants away from the bearing cavity. It also uses standard balancing to reduce residual vibration across the usable speed range.
