Product Description:

The MDD093C-N-040-N2M-110GA2 is an AC synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for connection to digital drive controllers, it supplies closed-loop rotary motion for indexing tables, packaging axes, and other automated stations that demand precise speed regulation and repeatable positioning. Within an industrial automation line, the unit integrates directly with controller feedback channels so the drive can command rapid torque changes during acceleration, deceleration, and position holding, while the built-in brake secures the load whenever power is removed.

The centering pilot on the flange is 110 mm, establishing the mechanical datum for concentric alignment with gearboxes or machine frames. Power and feedback cabling exit on the motor’s mounting face designated Side A, and they terminate on a sealed connector that permits cable changes without rewiring the motor itself. A spring-applied blocking brake delivers 22 Nm of static torque, allowing vertical or oscillating axes to remain stationary when the amplifier is disabled. Under continuous excitation, the rotor reaches a nominal speed of 4000 rpm, which supports short cycle times in high-response applications. Frame code 093 places the motor in the 093 outside diameter group, and the uncooled body uses length code C to provide additional active copper for higher power density. Standard dynamic balancing and a standard housing complete the primary mechanical layout.

Closed-loop accuracy is maintained through digital servo feedback (DSF) that reports rotor position to the drive at high resolution. Inside the feedback assembly, an integrated multiturn absolute encoder supplies absolute position data across multiple revolutions, so the control system can retain position information after power returns. The motor uses a plain shaft with a shaft seal, which helps keep oil mist or coolant away from the bearing chamber during normal machine operation. A standard balancing grade reduces vibration during rotation, and the sealed output area supports use in machinery where light contamination or fluid splash may be present.
