Product Description:

The MDD115B-N-030-N2M-130GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, the unit supplies precise torque and velocity regulation for indexing tables, gantry axes, and spindle drives used in automated packaging, assembly, and metal-cutting equipment. Standard mechanical balancing helps keep vibration within acceptable limits across the operating range. Its synchronous design supports accurate motion control during frequent starts, stops, and speed changes.

Mechanical alignment is aided by a centering diameter of 130 mm, allowing repeatable seating on standardized mounting flanges. When held at zero speed, the motor can sustain a continuous torque of 38.0 Nm, so static loads can remain supported without external gearing. A built-in integrated multi-turn absolute encoder records shaft position across multiple revolutions, and its data is conveyed through digital servo feedback (DSF) for direct interpretation by the drive. The rated rotational velocity reaches 3000 rpm, which suits high-speed motion sections. Power, feedback, and brake conductors terminate through a connector, which keeps the electrical interface compact and orderly.

Cables exit on the right side of the housing, a layout that simplifies routing inside tight cabinets. The integrated blocking brake produces 45.0 Nm of holding torque to secure vertical or suspended axes whenever the drive is disabled. A plain shaft without a side-B extension mates directly to couplings, and a shaft seal helps prevent oil or coolant from entering the bearing chamber. The motor uses a standard housing and has motor size 115 with length code B. The enclosed layout also helps protect the internal encoder area during operation.
