Product Description:

The MDD115D-N-015-N2L-130GL0 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled three-phase electrical energy into mechanical rotation for positioning, indexing, or load-regulation tasks across automated lines. The unit is compatible with Indramat servo amplifiers and provides a compact drive element where accurate velocity and torque control are critical to the motion sequence. This type of motor is commonly used where repeatable response is needed during start, stop, and speed changes. In automated equipment, that behavior supports coordinated motion between axes and stable process timing.

During continuous operation, the motor can deliver a standstill torque of 57.0 Nm, giving machinery sufficient low-speed force for holding or slow-feed duties without overheating. Its nominal mechanical speed is 1500 rpm, which matches typical gear ratios used in material-handling and forming equipment. A centering diameter of 130 mm ensures concentric location in the mounting flange, which helps minimize radial misalignment and vibration. Position and velocity are reported through digital servo feedback (DSF), allowing real-time closed-loop control by the drive. That feedback lets the controller track rotor movement continuously and correct deviations under changing load. Power, feedback, and brake connectors are oriented on the left side of the stator housing, and the interface uses a circular industrial connector. This layout helps keep cable routing consistent when the motor is installed in compact machine spaces.

This actuator follows the size code 115 and the length code D, so its active iron stack supports higher thermal throughput than shorter variants in the same frame. Dynamic balance follows the standard grading used for the series, which helps reduce bearing load during acceleration. The mechanical interface uses a plain shaft without a keyway, and a protective shaft seal helps retain lubricant while blocking fine contaminants. The connection end opposite the drive train is closed because the model is supplied without a side-B shaft end. That arrangement suits applications that only require power transmission from the main drive end. The motor is also supplied without a blocking brake, so an external holding device is required when power is removed.
