Product Description:

The MDD090B-N-040-N2M-130GA1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated current from a servo inverter into precise rotary motion for positioning and speed-controlled tasks in automated machinery. The unit integrates electrical feedback devices so control loops in packaging, printing, and material-handling equipment can respond quickly to load changes while maintaining repeatable motion. This arrangement allows the connected drive to correct speed and position deviations during continuous operation.

During operation, the motor reaches a nominal speed of 4000 rpm, which is suitable for medium-to-high-speed axes that require tight velocity regulation. At standstill, it can supply 7.2 Nm of continuous torque, providing stable torque output before acceleration begins. A blocking brake rated at 6.5 Nm secures the shaft when power is removed. Rotor alignment to mating mechanics is supported by a centering recess diameter of 130 mm, and dynamic vibration is limited through standard balancing. Position data is generated by an integrated multi-turn absolute encoder, while velocity data is transmitted through digital servo feedback. The motor is built in length code B with a standard housing, which gives it a consistent enclosure size for machine layout.

Cabling enters through the mounting side designated side A, and a keyed high-density connector simplifies cable connection without rewiring terminal strips. The drive end uses a plain shaft profile, and a molded shaft seal helps block lubricant migration toward the bearing zone. With motor size 090 and a single shaft end without a side B extension, the assembly fits compactly onto gearboxes or pulleys in space-limited drive trains.
