Product Description:

The MDD090A-N-040-N2L-130GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from the drive into controlled rotary motion for indexing tables, small pick-and-place stations, and light machine axes. Its synchronous design supports accurate speed regulation and repeatable positioning during short-cycle automation tasks. A standard housing, normal dynamic balancing, and a shaft end supplied without side-B extension keep the form factor compact. The motor is supplied without a blocking brake, so any required holding force must come from external mechanics or drive torque.

The centering pilot measures 130 mm, providing a precise reference surface for aligning the flange to a gearbox or machine frame. All power, feedback, and protective earth connections exit on the left side, simplifying cable runs in cabinets where busbars or ducts occupy the right section. A single industrial connector carries the power conductors and encoder lines, reducing installation time compared with terminal-strip designs. Rotor position and speed are reported through digital servo feedback (DSF), enabling high-resolution closed-loop control by the drive. Under rated excitation the rotor reaches 4000 rpm, matching medium-speed pick-and-place or spindle duties without overspeed derating.

The motor provides a continuous standstill torque of 3.7 Nm, allowing the axis to hold tooling or conveyors against static loads without thermal overload. The transmission interface is a plain shaft, so couplings must rely on frictional clamping because no keyway is machined. A dedicated shaft seal protects the front bearing from lubricant splash or airborne contaminants in fluid-rich environments. The motor has frame size 090, which matches the stator cross-section and bolt circle used across the series.
