Product Description:

The MDD112B-N-040-N2M-130PB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for closed-loop positioning and velocity tasks in automated machinery, the unit couples to digital drive controllers to convert commanded current into precise mechanical motion on production lines and handling systems. This operating role supports accurate speed regulation and repeatable axis movement in machines that depend on coordinated servo control.

This model delivers a continuous standstill torque of 17.5 Nm, giving machinery stable holding capacity before motion starts. During operation, it can reach a nominal shaft speed of 4000 rpm, allowing fast cycles when the drive supplies higher output frequency. A centering diameter of 130 mm provides the pilot fit that aligns the motor housing during mounting, while balancing is kept at a standard grade to limit vibration. Power and feedback cables exit on side B, and a single circular connector simplifies plug-in wiring. The motor uses a built-in shaft seal to help block lubricant migration along the keyed shaft and support sealing at the drive end.

Feedback to the controller is provided through digital servo feedback (DSF), while an integrated multi-turn absolute encoder supplies position data across multiple revolutions for startup without homing. The rotor uses a keyway so torque can be transmitted directly into couplings or pulleys, and the shaft end remains standard without a second extension on the opposite face. For applications that hold position through drive torque or external brakes, the motor is supplied without a blocking brake, which reduces mass and removes brake release wiring. Its connector layout and standardized frame dimensions support use with compatible Rexroth inverter modules in servo axes that require repeatable motion.
