Product Description:

The MDD112B-F-040-N2L-130GB0 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It operates with digital drive controllers to supply regulated torque and speed in automated machinery such as packaging stations, pick-and-place axes, and material-handling lines. By combining a liquid-cooled housing and digital feedback, the unit supports high duty cycles that require precise motion control and stable thermal behavior. Because the feedback device is integrated into the motor, the paired controller can continuously monitor rotor position and correct deviations during acceleration, deceleration, and steady-state running.

Its mounting geometry uses a centering diameter of 130 mm, allowing accurate alignment to gearboxes or adapter plates. Power and feedback connectors exit on side B, so cable routing can be planned accordingly. At standstill, the motor delivers 17.5 Nm of continuous torque, supporting static load holding when the drive maintains rated current. The motor is supplied without a blocking brake, so applications that need power-off holding must rely on an external mechanical latch or drive torque. The housing is prepared for liquid cooling, enabling higher continuous output by removing heat through an external coolant circuit rather than ambient air. This layout also keeps service access concentrated at one end of the motor body. The plug-in connector interface and standard rotor balancing help support smooth installation and stable operation at higher speeds.

The integrated digital servo feedback transducer returns high-resolution position data to the controller, enabling tight velocity loops up to the nominal speed of 4000 rpm. A compact B length code keeps inertia moderate while preserving torque density, which helps the motor accelerate and decelerate without unnecessary lag in cyclic motion. The drivetrain interface is a plain shaft built with a shaft seal to limit lubricant migration and particulate ingress. This configuration supports bidirectional operation with a standard shaft end on the drive side only, making the motor suitable for axes that must repeat fast moves with consistent commutation and controlled heat removal. It is well suited for applications that combine frequent starts, direction changes, and sustained running periods within the same operating cycle.
