Product Description:

The MDD090C-N-040-N2L-110GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an Indramat drive into controlled mechanical motion for positioning axes, feed drives, and pick-and-place gantries. Its electromechanical design allows closed-loop integration with Rexroth controllers in automated assembly, packaging, and printing equipment. This arrangement supports precise acceleration and deceleration in machines that depend on repeatable servo motion.

At the core of its performance envelope is a continuous standstill torque of 10.4 Nm, which allows the stator to deliver sustained twisting force without overheating. Under rated excitation, the rotor can reach 4000 rpm, enabling fast point-to-point moves. A centering diameter of 110 mm mates the flange accurately to machine frames and helps keep radial runout low. Power and feedback leads exit on side B, a layout that simplifies cable routing when the motor is rear-mounted. The factory-installed connector interface shortens installation time and keeps wiring consistent. Standard dynamic balancing, a standard housing, the 090 frame size, the C length code, and a single shaft end complete the mechanical arrangement indicated by this model code.

A blocking brake is integrated for safety stops, supplying a holding torque of 6.5 Nm to maintain position on vertical or suspended loads when the drive is disabled. Position signals are generated by the built-in digital servo feedback device, allowing the drive to close the velocity and position loops with high resolution. Motion is transmitted through a plain shaft, an arrangement that accepts couplings or pulleys without keyways while limiting stress concentrations. To protect internal bearings from coolant splash and dust ingress, a shaft seal is fitted so that the motor can be placed on the production floor without additional guarding. This combination supports stable holding and consistent motion control during frequent start-stop operation.
