Product Description:

The MAC112C-0-ED-4-C/130-A is a permanent-magnet AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, it transforms current commands from a controller into precise shaft rotation for positioning, speed regulation, and coordinated motion in automated production equipment. The feedback arrangement supports repeatable speed control during continuous duty. Because it is built for analog drive systems, it suits machines that rely on external control loops rather than integrated digital electronics.

A centering flange diameter of 130 mm aligns the housing accurately on the machine plate and helps minimize eccentricity. Cooling is done by natural convection, so heat is removed through surface radiation and airflow without auxiliary fans. The motor has a rated speed of 3000 rpm under nominal load. Rotor position is sensed by incremental or absolute encoder feedback, enabling either pulse counting or multi-turn angle reporting to the drive electronics. The feedback system also provides a tacho signal of 3 V/1000 rpm, giving the controller a linear voltage that is proportional to speed for closed-loop regulation.

The motor uses motor length C and motor size 112, which establish the housing proportions, shaft extension, and mounting hole pattern needed for compatibility with mid-frame gearboxes or direct-drive couplings in production machinery. Power conductors are routed through a connector on side A, keeping cable egress on the same face as the feedback connection for cleaner routing in compact installations. The winding code is ED, which matches the stator coils to drives that provide the required voltage and current range. This layout helps the motor fit organized analog motion systems where space around the mounting face and cable exit path is limited.
