Product Description:

The MDD090A-N-040-N2M-130PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into controlled rotary motion for automated axes. The unit fits medium-frame installations that require repeatable positioning and moderate continuous torque in packaging machines, material-handling modules, and general factory automation. Its mechanical interface follows IEC dimensions, which helps it fit standard machine layouts.

The motor uses a standard housing with balanced rotor support, and the flange centers on a 130 mm pilot diameter for accurate coaxial alignment with gearboxes or direct-drive loads. The nominal shaft speed reaches 4000 rpm, allowing rapid cycle operation when paired with a suitable drive. Continuous stall torque is rated at 3.7 Nm, and this value is available without additional cooling. Power and feedback conductors exit on the right side through a sealed connector, which helps simplify cable routing in compact installations. Rotary power is transmitted through a keyway shaft end that helps resist slip during repetitive acceleration.

Position information is supplied by an integrated multi-turn absolute encoder, which reports angular position through digital servo feedback channels for closed-loop commutation and synchronization. The motor has size code 090 and length code A, and it is fitted with a shaft seal on the output side to help protect against coolant spray and airborne particles. Because the unit is built without a blocking brake, inertia remains low for axes that rely on drive torque or external clamps for holding duty. The enclosure uses a standard configuration, and the balanced design supports stable operation in typical industrial motion applications.
