Product Description:

The MDD115D-N-015-N2M-130GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts inverter current into precisely regulated mechanical motion for automated axes that require constant torque at low speeds. The motor size of 115 and length code D place it toward the higher end of the series range, making it suitable for positioning tables, presses, and similar industrial tasks. Its synchronous design supports accurate speed regulation and repeatable positioning in servo-controlled equipment.

At standstill, the motor can maintain 57.0 Nm of torque, so heavy loads remain under control without extra gearing. Rated operation is reached at 1500 rpm, and pairing this speed with the available torque provides a predictable power profile for closed-loop drives. Mounting precision is supported by a centering diameter of 130 mm, which aligns the flange to the machine frame and limits radial runout. Feedback is supplied through digital servo feedback (DSF), while an integrated multi-turn absolute encoder reports shaft position over multiple revolutions and removes the need for homing after power cycles. This combination lets the controller track both speed changes and absolute position during startup and normal motion. Power and signal conductors terminate through a single connector, which keeps the wiring interface compact and supports orderly cable routing.

The wiring interface is oriented on Side A, helping keep cables clear of adjacent equipment when the motor is installed in tight mechanical assemblies. It uses a plain shaft, which suits direct torque transfer through compatible couplings without a keyed connection. The front end is protected by a shaft seal that helps block coolant splash and dust at the bearing seat. Because the unit is supplied without a blocking brake, applications that need holding torque during power-off conditions must rely on external clamping or drive torque. The shaft end is present only on the drive side, and standard dynamic balancing helps reduce vibration during operation.
