Product Description:

The MDD112B-N-040-N2L-130PA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is used as a servo actuator in digital drive systems where rapid acceleration, precise speed control, and repeatable positioning are required. By combining permanent-magnet excitation with electronic commutation, the motor converts drive controller commands into controlled mechanical rotation for automated machinery and production lines. This type of motor is well suited for axes that must respond quickly to changing motion commands while maintaining stable operation during continuous industrial use.

The unit has a nominal speed of 4000 rpm, giving the drive controller a broad operating range for high-cycle applications. At standstill, it can deliver 17.5 Nm of continuous torque, which supports stable low-speed operation and sustained load holding under controlled conditions. Accurate mechanical alignment is supported by a centering diameter of 130 mm, and the motor has a frame size of 112, placing it in the mid-power range of the series. Power and feedback conductors exit on Side A, which helps keep cable routing orderly when multiple axes are installed close together in the same machine layout.

The motor is supplied without a blocking brake, so holding force must be provided by external clamping or drive-applied torque when power is removed. Position data are transmitted through digital servo feedback, allowing the controller to make precise corrections during speed and position control. The shaft is fitted with a shaft seal, which helps protect the bearing area from coolant and dust. Electrical connections are made through a rugged connector interface, and the output shaft uses a keyed design for standard coupling attachment. The motor uses a single-ended shaft arrangement with no side B stub, and it has standard rotor balancing, a standard cooling surface, and motor length code B for series compatibility.
