Product Description:

The MAC112D-1-ED-3-C/130-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Designed for analog drives, it converts command signals from legacy servo amplifiers into controlled rotary motion for positioning axes and speed-regulated machinery. This type of motor is suited for packaging equipment, transfer systems, and other automation tasks that need repeatable motion without added gear stages. In closed-loop operation, the paired amplifier can use motor feedback to correct speed deviations during load changes and maintain consistent motion over repeated cycles.

A centering shoulder of 130 mm helps align the housing with mating machine flanges during installation. The frame uses size 112 with the extended D length, giving the motor a larger housing format for higher continuous torque than shorter versions in the same family. The motor reaches a nominal speed of 3000 rpm, which suits many positioning and constant-speed applications. The ED winding code identifies the electrical winding layout used in this motor, and power enters through a single connector on side A. The motor is supplied without a blocking brake, so any static holding force must come from the drive or external mechanics.

The cooling system uses a blower powered by AC 230 V and moves air along the housing for axial surface cooling. Feedback is provided by a tacho generator that produces 3 V/1000 rpm, and the motor uses tacho feedback with a second shaft end for analog speed-control circuits that need a direct feedback signal. The second shaft end can also support auxiliary monitoring functions where the application requires an additional mechanical pickup point. Forced airflow helps the motor maintain stable thermal operation during demanding duty cycles where natural convection alone would be less effective.
