Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2M-130PB1, a synchronous AC servo motor in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical current into precise mechanical rotation for axes that demand repeatable positioning and speed in industrial automation cells, machine tools, and handling systems. Its mechanical design matches standardized mounting patterns used across the product line, which helps the motor fit common machine layouts. This supports straightforward integration on feed axes, transfer units, and positioning tables where stable closed-loop motion is required.

The motor’s centering pilot measures 130 mm, allowing concentric alignment against equipment flanges to minimize radial runout during high-speed service. Power and feedback cables exit on Side B, a configuration that simplifies routing in cabinets where space behind the motor is limited. A sealed connector interface carries all phase, signal, and ground conductors, eliminating loose pigtails. At standstill, the stator can deliver a continuous torque of 7.2 Nm, so the axis can sustain load without overheating during rated operation. When energized by the associated drive, the rotor reaches a nominal speed of 3000 rpm, providing a balance between responsive acceleration and acceptable bearing life. That operating speed suits many direct-coupled and belt-driven axes that need quick response without excessive mechanical stress.

Position feedback is handled by an integrated multiturn absolute encoder, giving the controller absolute shaft angle over multiple revolutions and removing the need for homing routines after startup. This signal is transmitted through digital servo feedback (DSF), which improves immunity to electrical noise compared with analog formats and supports reliable position data during dynamic motion. A mechanical keyway on the output shaft secures couplings against slip during bidirectional torque reversals. For static load holding or emergency stops, the built-in brake supplies 6.5 Nm of torque and is engaged automatically when power is removed. The motor also uses a standard housing with a shaft seal, standard balancing, and motor length code B for general machine-duty installation.
