Product Description:

The MDD115A-F-030-N2L-130GB0/S028 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for direct coupling to digital drive controllers where fast position and velocity loops are required in automated machinery and material-handling systems. This type of motor is well suited for axes that need responsive acceleration, stable speed control, and accurate positioning during repeated machine cycles. Its housing also supports integration into coolant circuits used in high-duty-cycle installations.

The motor delivers 28.0 Nm of continuous torque at standstill, giving the drive enough static force to hold or index loads without additional gearing. A nominal speed of 3000 rpm sets the upper continuous operating velocity when the controller supplies rated current. The centering diameter of 130 mm aligns the stator housing with the machine frame and helps maintain concentricity between the motor and the driven mechanics. The housing is prepared for liquid cooling, so coolant can remove heat from the stator during demanding duty cycles. Power and signal leads exit from side B, which can simplify cable routing when the flange faces the machine bed. This arrangement can be useful where available cable space is limited near the mounting surface.

The motor uses digital servo feedback (DSF) to send high-resolution rotor position data to the controller, supporting accurate commutation and low-speed positioning. It has a shaft seal that helps limit the ingress of coolant or lubricants into the bearing chamber in washdown or oil-mist environments. The output is a plain shaft, allowing couplings or pulleys to be fitted without keyways when low backlash is required. The motor is supplied without a blocking brake, so holding torque must be provided by the drive or by an external mechanical lock when power is removed. This layout is appropriate for systems that already rely on controlled motor torque or separate holding hardware during stops.
