Product Description:

The MDD090B-N-030-N2M-130PL1 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It converts controlled three-phase drive outputs into precise rotary motion for machine tools, packaging lines, and assembly stations in industrial automation. Position data is returned through digital servo feedback, allowing the controller to maintain accurate speed regulation and repeatable positioning during closed-loop operation. This arrangement supports synchronized motion on axes that must respond consistently during frequent starts, stops, and directional changes.

The motor uses standard balancing so vibration is minimized at its nominal operating point. A flange centering diameter of 130 mm aligns the housing concentrically with gearboxes or machine frames, and the 090 frame size with length code B gives the unit a mid-range body that fits shallow installation spaces. When energized, the rotor can sustain a continuous standstill torque of 7.2 Nm, allowing the axis to hold load without exceeding permitted winding temperature. Under motion, the shaft reaches a nominal speed of 3000 rpm, which matches the operating range of typical Indramat inverter stages. All terminations exit on the left side, simplifying cable routing, and a sealed connector pair provides single-point power and signal entry.

A multiturn absolute encoder inside the rear housing tracks up to 4096 revolutions, so the motor can retain position information after power loss without requiring a homing cycle. The unit is supplied with a blocking brake rated at 6.5 Nm, and it engages automatically to secure vertical or indexing loads. Power and feedback pins share a rugged connector, so installation uses one interface for both electrical paths. The keyed shaft uses a keyway to transmit torque, and the design omits a side B shaft end to keep the motor length compact. The housing also includes a shaft seal that helps protect the output end during operation.
