Product Description:

The MAC112D-0-ED-1-B/130-A-1/I1250/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts controller commands into precise rotary motion for positioning tables, conveyors, or pick-and-place heads in industrial automation cells. Its housing follows the dimensions of the MAC 112 frame for installation in a compatible machine mount. The motor integrates feedback components that support closed-loop control of shaft position and velocity during automated motion sequences.

A standard blocking brake delivers 45 Nm of holding torque, preventing shaft movement when power is removed and keeping vertically loaded axes from drifting. Accurate mounting is aided by the 130 mm centering diameter, which seats the front flange concentrically on the machine plate. Heat generated in the stator is removed through natural convection, so no external blower or liquid circuit is required. Under rated operating conditions, the rotor reaches 3000 rpm, a speed that matches common gearbox ratios and supports rapid indexing duties. Motion feedback is provided by an incremental encoder feedback system, which supplies differential pulses for high-resolution velocity and position control when paired with a compatible analog drive. The encoder signals allow the controller to detect changes in motion and correct deviations while the axis is operating.

For speed monitoring during drive calibration, the built-in tacho generator outputs 3 V/1000 rpm. This linear voltage allows actual shaft speed to be verified with a suitable measuring instrument. Power conductors exit through a connector on side A, allowing cable runs to follow the required orientation within the machine. The motor has a frame size of 112, while the D stack length provides a longer active core for increased continuous torque. Electrical characteristics are set by winding code ED, ensuring that the motor draws the appropriate current when connected to legacy analog amplifiers designed for its resistance and inductance profile. The cable orientation also helps keep the power connection clear of the output shaft and nearby mechanical components.
