Product Description:

The MAC112C-0-ED-3-C/130-A-2/S018 is a servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages from classic servo amplifiers into controlled rotary motion for positioning and speed loops in factory machinery. The unit is suited for mid-frame applications where fast acceleration and dependable holding are required, so it can support mechanical loads without relying on external gear reduction. It is commonly used on transfer lines, packaging axes, and other equipment that continues to operate with legacy motion hardware.

The integrated heavy-duty blocking brake delivers a holding torque of 60 Nm, preventing shaft drift when vertical or cantilevered loads are parked. Accurate mechanical alignment is supported by a centering diameter of 130 mm, which fits standard flanges without additional sleeves. The motor uses frame size 112, giving a stator cross-section that balances thermal mass with dynamic response. The stack length code C indicates a longer active iron length than shorter versions in the same frame. Winding code ED identifies the electrical winding used with compatible Indramat analog servo drives.

Thermal management relies on natural convection, so installation space must permit free airflow around the housing. The feedback arrangement includes tacho feedback and a second shaft end, combining speed feedback with an auxiliary shaft extension for additional mechanical or feedback components. The standard tacho generator produces 3 V/1000 rpm, which supports speed loops with moderate resolution. The motor reaches a nominal speed of 3000 rpm, which suits many legacy transmission ratios used in 50 Hz and 60 Hz machinery. Power conductors exit through a connector on side A, keeping cable routing at the drive end of the machine frame and leaving the opposite shaft area available for couplings or auxiliary devices.
