Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-040-N2M-130GA0 synchronous servo motor within the MDD Synchronous Motors series. The unit is classified as a motor for digital drive controllers and converts inverter commands into controlled rotary motion. In automated assembly cells, pick-and-place modules, and small conveyor sections, it delivers repeatable torque and speed so that mechanical loads follow programmed trajectories. This operating profile suits equipment that depends on accurate starts, stops, and speed changes during repeated production cycles.

The motor supplies a continuous standstill torque of 3.7 Nm, so it can hold load at zero speed without thermal overload when the shaft is locked. Under rated excitation, it reaches a nominal speed of 4000 rpm, supporting short cycle times for light-to-medium inertia loads. Accurate mounting is assisted by a centering diameter of 130 mm, and standard balancing helps keep residual vibration low at the mounting interface. Rotor position is resolved by an integrated multi-turn absolute encoder, while digital servo feedback (DSF) provides real-time position and diagnostic data to the drive. This feedback arrangement supports stable motion control during changing load conditions and repeated positioning moves. All power and feedback conductors enter on Side A, so surrounding machine layout must leave clearance at that face.

A connector interface handles power, feedback, and protective earth, enabling quick connection without opening the housing. The motor has size 090 and length code A, giving it a compact body that fits machines where installation space is limited. The output end is a plain shaft without a side-B extension, and it uses a shaft seal to limit lubricant escape and airborne contamination. Because the model is supplied without a blocking brake, external holding measures are required when static position retention is necessary. The closed housing layout also helps keep the connection points organized around a single motor entry area.
