Product Description:
The MDD090B-N-030-N2M-110PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts regulated armature current into rotary torque for positioning tables, feed screws, and automated handling modules. Its construction matches the mechanical envelope expected in modular machine frames, allowing the motor to be integrated into existing Rexroth servo axes without modification. By providing closed-loop velocity and position control, it links programmable logic instructions to physical motion in industrial automation cells.
The mechanical interface follows a centering diameter of 110 mm, which aligns the stator housing concentrically with attached gearboxes or mounting flanges. Electrical and signal conductors leave the housing on side B through a single connector, which simplifies cable routing when the motor is mounted lengthwise. Under continuous stall conditions, the motor delivers 7.2 Nm of torque, and it sustains synchronous operation up to 3000 rpm when the drive applies its rated frequency. Angular feedback is returned over digital servo feedback (DSF), providing high-resolution position data for the controller while standard dynamic balancing limits vibration during high-speed reversal.
Position accuracy is refined further by the integrated multiturn absolute encoder, which records shaft revolutions even when power is removed. A front shaft seal protects the bearing section against coolant splash or airborne particles, and torque is transmitted through a keyway shaft. Because the motor is supplied without a blocking brake, holding force must be provided by the drive or an external clamp during stationary periods. The motor has a standard housing, size 090 with length code B, a connector-based wiring interface, and a single shaft end.
