Product Description:

The MDD090C-N-040-N2L-130GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat under the MDD Synchronous Motors series. Intended for coupling with digital drive controllers, the unit converts drive current into controlled mechanical rotation for positioning and velocity loops. Typical applications include gantries, packaging axes, and material-handling modules where repeatable servo response is required.

It delivers a continuous standstill torque of 10.4 Nm. This is the torque the motor can supply continuously at standstill without overheating. During motion, the rotor can reach a rated speed of 4000 rpm, matching drive outputs that supply the corresponding electrical frequency during closed-loop operation. Power and feedback plugs are located on side B of the housing, so cabling is routed toward the rear. The motor uses a sealed connector interface for secure electrical connections. The centering pilot measures 130 mm, giving the mounting flange the concentric accuracy required for high-precision couplings. The motor uses standard dynamic balancing and a standard enclosure to keep the rotating mass evenly distributed. Motor length code C sets the active stack so thermal dissipation matches the continuous torque level.

For power-off holding, a blocking brake is fitted. It generates 11.0 Nm of static torque and prevents axis drift on vertical loads until drive power is restored. Position feedback is supplied through digital servo feedback (DSF), allowing the controller to read high-resolution rotor angle data and maintain precise position and speed regulation. The mechanical interface uses a plain shaft with an internal shaft seal, limiting lubricant escape and helping keep fine dust away from the bearing area. The motor has size 090 and a single-ended shaft without a side-B extension. Its compact form suits tightly spaced machine layouts.
