Product Description:

The MAC112C-0-ED-4-C/130-A-0/WJ520LX/S05 is a servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts control voltages from legacy servo amplifiers into mechanical rotation for positioning and velocity tasks in industrial automation cells. The unit is suitable for machine tools, packaging lines, and material-handling axes where stable closed-loop speed regulation and repeatable motion are required.

With a centering diameter of 130 mm, the motor aligns precisely against mounting flanges and helps keep runout low. Its nominal shaft speed reaches 3000 rpm, providing a practical base velocity for rapid point-to-point moves when it is paired with an analog controller. Heat is removed through natural convection, so no auxiliary fan or liquid circuit is required, which leaves cabinet airflow arrangements less complicated. The motor has no blocking brake, so the shaft is held at standstill only by drive torque or external machine restraint. Power conductors terminate through a connector on side A, which supports straightforward cable routing in layouts that keep wiring on one side of the axis.

Size code 112 indicates the stator diameter and pairs with motor length C to establish the torque range expected from this frame. The electromagnetic layout uses winding code ED, allowing compatible analog drives to match the motor’s electrical behavior without additional parameter changes. For velocity feedback, the tacho generator delivers 3 V/1000 rpm, and the secondary channel provides incremental or absolute encoder signals so retrofit systems can use pulse-based or absolute position feedback. This arrangement supports applications that need speed information from the tacho stage while also using encoder data for axis monitoring and control.
