Product Description:

The MDD090B-N-040-N2L-110GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for use in automated motion axes within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated DC link energy into rotary torque that can be controlled with high resolution, allowing indexers, packaging stations, and gantry systems to follow commanded position and speed targets. The design combines permanent-magnet excitation with electronic commutation to provide stable torque across its operating range. Its integrated layout supports precise axis control in machine spaces where compact installation and clean cable routing are important.

The flange has a centering pilot of 110 mm, which supports accurate concentric mounting on gearboxes or direct-drive tables. The motor uses a B length housing that provides a mid-frame body with good stiffness and moderate overall size. Power and feedback lines exit on side A, and a keyed connector provides a secure electrical interface for the cable set. Under continuous excitation, the motor can deliver 7.2 Nm at standstill, and the winding supports speed regulation up to 4000 rpm without derating. Rotor and flange follow a standard balancing grade, and the housing uses the standard enclosure style for this frame.

A blocking brake is integrated and provides a holding moment of 11.0 Nm to restrain vertical loads when power is removed. Position data is returned through Digital servo feedback (DSF), allowing accurate commutation and fast response to motion commands from the drive. A shaft seal helps reduce the entry of contaminants, and the drive end uses a plain shaft for coupling to the load. The frame corresponds to motor size 090, which keeps rotor inertia suitable for moderate-power servo applications. The opposite shaft end has no extension on side B, which helps keep the mechanical arrangement simple.
