Product Description:

The MDD093B-N-020-N2M-110GR1 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers where a compact rotary actuator is required for coordinated positioning and velocity loops in automated machinery. By combining permanent-magnet excitation with electronic commutation, the unit converts drive current into regulated mechanical motion for tasks such as indexing tables, packaging axes, or material-handling gantries.

The rotor is balanced to standard quality to limit vibration, while a centering diameter of 110 mm aligns the flange precisely on mounting fixtures. Rated continuous torque at standstill reaches 14.5 Nm, so the axis can deliver static holding force without overheating. At rated bus voltage, the motor reaches a nominal speed of 2000 rpm, giving moderate output for mid-range feed drives. A blocking brake is integrated, and its static holding capacity is 11 Nm, allowing the load to remain locked during power removal. Position data originate from an integrated multi-turn absolute encoder that feeds the drive with multi-revolution feedback. The housing uses standard cast construction, the size code is 093, the length code is B, and all electrical and feedback plugs exit on the right side of the stator to suit cabinets arranged on that flank.

Signal and power conductors mate to a connector that simplifies cable connection. The drive interprets position through digital servo feedback (DSF), enabling absolute referencing after power-up. Mechanical power is transmitted through a plain shaft that follows DIN keyless practice, and the front bearing area is protected by a shaft seal to keep lubrication in and contaminants out. A standard single-ended shaft configuration on side A, with no extension on side B, helps minimize overall length. The unit is classified as a motor for digital drive controllers and is compatible with SERCOS-based amplifiers.
