Product Description:

The MAC112D-0-ED-4-C/130/A-0/W154LX/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it delivers closed-loop torque and speed control in positioning axes and general machinery. Within an automation cell, the unit converts drive current into rotational motion so associated controllers can regulate mechanical output precisely. Its layout supports applications that need steady response during repeated starts, stops, and speed changes.

Its mounting interface relies on a centering diameter of 130 mm, allowing alignment with gearboxes or flanges without additional bushings. Heat is removed through natural convection, so the housing depends on free air circulation rather than fans or liquid circuits. Under rated electrical frequency, the rotor stabilizes at 3000 rpm, a speed suited to common direct-drive or belt-coupled arrangements. Power leads exit through a connector on side A, which can simplify cable routing along the machine bed, and the stator stack uses the D length to provide higher output than shorter versions in the same frame family.

The rotor and laminate diameter correspond to size 112, placing the unit in the mid-torque range of the series. Speed feedback is supplied by an incremental or absolute encoder with tacho feedback, allowing analog controllers to read velocity while also supporting position control when the absolute channel is used. For each thousand revolutions, the integrated tacho generates 3 V/1000 rpm, which provides a clear signal for regulation and controlled deceleration. The internal copper uses winding code ED, which corresponds to the electrical characteristics expected by compatible drives. Because the motor does not include a blocking brake, any vertical axis must hold the load with external clamping or sustained drive torque.
