Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI520LV servo motor is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive controllers, it converts drive output into accurate rotary motion for automated cutting heads, transfer arms, and indexing tables where steady response is required. Its electromechanical configuration supports consistent torque and speed regulation, allowing integration into industrial lines that require repeatable axis positioning. The motor is suited to applications in which an external drive amplifier handles the control loop while the motor provides the rotary output and feedback signals needed for stable motion.

A centering diameter of 130 mm provides precise alignment against gearboxes or mounting flanges. Heat is removed through natural convection, so airflow around the housing must remain unobstructed during continuous duty. The rotor reaches a nominal speed of 3000 rpm. A built-in tacho generator supplies 3 V/1000 rpm, giving the analog controller proportional velocity feedback during acceleration and steady-state operation. Power conductors are routed through a connector on side A, which can simplify cable routing when the motor is installed beside other drive components or close to a machine frame.

The motor has size 112 and length code C, which indicate its frame proportions and housing depth. Winding code ED identifies the electrical winding used for this motor version. The unit is supplied without a blocking brake, so the shaft is not held when power is removed. For motion feedback, it uses an incremental encoder fitted in the standard position, and the auxiliary tacho feedback channel can be wired as incremental or absolute depending on system requirements. Tacho quality is standard, matching the accuracy expected by analog velocity loops.
