Product Description:

The MAC112D-0-ED-4-C/130-A-1/WI520LV/S005 servo unit is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As a motor for analog drives, it supplies closed-loop speed and position control to machinery that still relies on analog command interfaces rather than newer digital networks. Within an automation line, it converts electrical drive signals into controlled mechanical rotation, allowing packaging axes, material-handling gantries, or forming presses to follow precise motion profiles with repeatable motion during production.

At a nominal shaft speed of 3000 rpm, the motor can match the velocity loops common to MAC analog controllers without additional gearing. Heat generated by copper losses is removed by natural convection, so the housing must be mounted where ambient airflow is unobstructed. The flange includes a centering diameter of 130 mm that positions the stator concentrically against the machine wall and helps keep runout within tolerance. A frame size of 112 contributes to the continuous torque class expected from this D-length model. When mains power is removed, a spring-applied blocking brake produces 45 Nm of static holding torque, preventing uncommanded motion on vertical axes.

Power conductors terminate through a plug oriented connector on side A, allowing the cable to exit in the same direction as earlier MAC112 installations. The solid shaft carries a DIN 6885 keyway, so couplings or pulleys with standard keys can be fitted without custom machining. For velocity feedback, the internal tacho generator delivers 3 V/1000 rpm, which the drive card converts directly to an error signal, while position loops can rely on the incremental encoder that shares the same mounting pilot. Electromagnetic characteristics are set by winding code ED, giving resistance and inductance values compatible with legacy ±10 V command amplifiers.
