MDD090C-N-030-N2M-110PA2

The MDD090C-N-030-N2M-110PA2 is a three-phase synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with the company’s digital drive controllers where it converts commanded current into controlled rotary motion. Standard housing dimensions and dynamic balancing allow the unit to integrate directly into packaging, materials-handling, or tooling equipment that requires precise speed regulation and repeatable positioning throughout continuous duty cycles. It employs permanent-magnet excitation and closed-loop feedback to keep torque and velocity within narrow tolerances during rapid load changes.

The motor delivers a continuous standstill torque of 10.4 Nm, providing stable force for static loads without overheating. Its rated mechanical speed reaches 3000 min⁻¹, so the shaft can follow typical 50/60 Hz command frequencies through a 1:1 electronic pole relationship. Power and feedback conductors exit on Side A, permitting cable routing along the drive side of the machine. A single-piece circular Connector handles phase, brake, and encoder wiring, simplifying installation. Precise concentricity is maintained by a centering diameter of 110 mm, which aligns the stator to the mounting flange.

For position acquisition, the integrated multiturn encoder feeds digital servo feedback to the controller, enabling absolute position recovery after power cycling. A blocking brake rated at 11.0 Nm locks the rotor when the drive is disabled, preventing back-driving on vertical or indexing axes. The output shaft follows a keyway profile, giving positive mechanical engagement with couplings or pulleys. Contaminant ingress is limited by a shaft seal that retains lubrication and guards against dust and spray, so the motor can operate reliably in general-purpose factory environments without additional sealing hardware.
