Product Description:
The MDD090B-N-040-N2L-130PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers precise torque and speed regulation for indexing tables, pick-and-place axes, and similar industrial automation duties. Its electromagnetic design supports rapid acceleration and accurate positioning when paired with a compatible drive stage. This operating profile is useful in applications that need repeatable starts, stops, and direction changes without losing motion accuracy under changing load conditions.
At installation, the motor centers on a flange diameter of 130 mm, and its power and feedback plugs face side B, which can simplify cable routing in compact cabinets. A sealed connector interface carries the three-phase stator lines and serial feedback signals. Under stall conditions, it maintains 7.2 Nm of continuous torque, while a spring-applied brake supplies 11.0 Nm for holding during power-off states. Closed-loop regulation is supported by integrated digital servo feedback (DSF). Standard dynamic balancing reduces vibration in the 090 frame, and the B length code adds stack height for higher torque density without changing the mounting footprint. The housing uses a standard uncooled design, and the shaft is present only on the drive side to reduce mass at the non-drive end.
At a nominal speed of 4000 rpm, the rotor delivers consistent motion that matches drive commands and transmits power through a keyway shaft to couplings or gearheads. A factory-installed shaft seal helps block oil mist and process dust from entering the front bearing. The keyed output provides positive torque transfer for connected mechanical elements, while the front sealing helps protect the bearing area in dirty process zones. The motor uses a single-ended shaft and standard housing, and the connector orientation helps preserve clearance for nearby components while the encoder maintains position feedback across the speed range.
