Product Description:

The MDD090A-N-030-N2L-110PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into repeatable torque and speed for industrial automation axes such as packaging formers, pick-and-place heads, and indexing tables. A standard housing and balancing class help keep mechanical vibration low during cyclic motion. The motor also uses a single-ended shaft arrangement that simplifies coupling to gearboxes or direct-drive loads in compact machine layouts.

The centering diameter is 110 mm, which allows precise face mounting without additional pilot rings. A continuous standstill torque of 3.7 Nm can be maintained so static loads remain supported without overheating during normal operation. The winding supports a nominal speed of 3000 rpm, giving the axis enough top-end velocity for rapid cycles and short transfer moves. Electrical power, resolver lines, and thermal sensor connections exit on Side A, and a single industrial connector mates all conductors to reduce cable entry points. The 090 frame size and A-length body keep the package compact while still fitting common servo installations that require accurate positioning and stable thermal behavior.

Because the motor is supplied without a blocking brake, any holding action during power-off must be provided by mechanical locks or drive torque. Rotor position data is generated through Digital servo feedback (DSF), allowing the drive to support fine current control and routine diagnostics during operation. Torque is transferred through a hardened shaft with a keyway, and contamination resistance is improved by construction with a shaft seal. The absence of a secondary shaft end keeps the drive side simpler, and the compact active length helps limit inertia for repeated start-stop duty on handling axes and similar automated equipment.
