Product Description:

The MDD090A-N-040-N2L-110GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies commanded torque and speed to automated axes in assembly lines, packaging units, and processing cells. Its synchronous operating principle supports precise speed regulation and repeatable positioning during acceleration, dwell, and reversal. This makes the motor suitable for feed axes and transfer systems where compact dimensions are important and stable response must be maintained across repeated duty cycles.

The centering flange has a 110 mm reference diameter that aligns the housing to gearboxes or machine frames and helps keep the shaft concentric. When energized at rated current, the rotor can produce 3.7 Nm of continuous holding torque at standstill, so it can support static loads without overheating. Under rated excitation, the shaft reaches a nominal speed of 4000 rpm, matching drive controllers that output high-frequency sinusoidal currents. Power and feedback conductors leave the unit on Side A, and the plug-in connector keeps cable routing concentrated at one end of the motor. With a frame size of 090 and a standard housing design, the motor fits installations where servo axes must be mounted in limited space.

A factory-installed blocking brake provides 11.0 Nm of static braking torque, allowing vertical or suspended axes to hold position when power is removed. The single-ended, plain shaft is supplied without a secondary shaft on side B, so couplings mount directly on the smooth output surface. Rotor angle and speed are reported through digital servo feedback (DSF), enabling high-resolution closed-loop control without an external encoder package. A fitted shaft seal helps prevent oil or coolant from migrating along the journal into the motor interior. The motor also uses length code A, a single circular connector, and a standard housing style.
