Product Description:

The MDD090A-N-040-N2L-130GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the MDD Synchronous Motors series. It is engineered for use with digital drive controllers where rapid cyclic positioning or velocity control is required on automated axes such as pick-and-place arms, gantry modules, or packaging spindles. By delivering closed-loop torque and speed in a compact frame, the unit functions as an electromechanical actuator that converts drive current into rotary motion for industrial automation machinery.

The motor body is aligned with a centering pilot of 130 mm, providing a stable fit against precision mounting surfaces and helping maintain repeatable shaft concentricity. At standstill, it can exert a continuous torque of 3.7 Nm, enabling static load support without overheating when the drive holds position. The motor reaches a nominal speed of 4000 rpm during operation. At this speed, the electromagnetic field produced by the stator stays synchronized with the rotor magnets so commanded speed matches actual output. Power and feedback conductors exit on the right side of the housing, which simplifies cable routing in cabinets where drives are stacked horizontally. Position data is returned through digital servo feedback, allowing high-resolution monitoring that supports fast loop updates and minimizes following error during acceleration or reversal.

The frame is size 090 with length code A, indicating the shortest stack in this diameter and reduced mass where low inertia is required. A factory-installed shaft seal blocks coolant spray or fine dust from entering the bearing cavity. The shaft is a plain shaft, so torque is transferred through friction or clamping hubs instead of keyways, reducing stress concentrations on the journal surface. Standard dynamic balancing and a connector-style power interface are included, and the motor is supplied without a blocking brake for applications that rely on drive torque or external clamps to hold position.
