Product Description:

The MDD090B-N-040-N2L-130GB2 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed to pair with compatible digital drive controllers, the unit converts electrical command signals into controlled rotary motion for positioning tables, gantry axes, and material-handling devices in automated lines. Its compact B-length housing, standard balancing grade, and sealed construction support installation in enclosed machine spaces where accurate speed control and repeatable motion are required. This layout suits automated equipment that depends on short response times, stable servo behavior, and reliable operation through frequent start-stop cycles.

It installs to machinery through a flange that carries a centering diameter of 130 mm, enabling repeatable coaxial alignment without shims. All power and sensor leads exit on Side B through a keyed Connector, which helps keep cable routing orderly and maintains consistent strain relief at the motor entry point. Under steady excitation, the motor can develop a continuous standstill torque of 7.2 Nm, so static loads on vertical or high-friction axes can remain supported during controlled holding conditions. When commanded by the drive, the rotor can reach a nominal speed of 4000 rpm, allowing fast indexing and high cycle rates in pick-and-place units, transfer mechanisms, and similar servo-driven assemblies.

Position retention during emergency stops is handled by an integral blocking brake that furnishes 11.0 Nm of holding torque, reducing the need for separate holding hardware on power-off axes. Real-time commutation data is returned through the motor’s digital servo feedback interface, giving the controller precise angle information for smooth interpolation and stable closed-loop correction during changing loads. A plain shaft with a shaft seal helps limit lubricant migration while still accepting common coupling styles used in servo installations. Its frame designation 090 keeps the motor within a compact mechanical envelope, which supports responsive motion on axes where installation space and moving mass must be controlled.
