Product Description:

The MAC112D-0-ED-3-C is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for precision motion tasks in industrial automation, where electrical input from analog drive amplifiers is converted into controlled rotary power. The motor is suitable for positioning, indexing, and coordinated multi-axis movement in equipment such as packaging lines, material-handling stations, and light machine-tool axes. Its operating concept fits installations that rely on established analog control architecture rather than newer network-based motion platforms.

Thermal management relies on natural convection, so the housing must be installed where surrounding air can carry heat away without fans or liquid cooling. With frame code 112, the motor uses the larger MAC mounting format associated with this housing size, which supports a broader magnetic circuit and higher torque capability than smaller frames. The stator uses winding code ED, matching the electrical characteristics expected by compatible legacy MAC drive amplifiers. Under rated excitation, the rotor reaches 3000 rpm, providing a common operating speed for production machinery that needs steady velocity control. Velocity feedback comes from an internal tachogenerator with an output of 3 V/1000 rpm, giving the drive a linear reference signal for closed-loop regulation during acceleration, deceleration, and steady-state running.

The mechanical arrangement is specified as with tacho feedback and a second shaft end, so the motor can support auxiliary mechanical coupling without additional shaft machining. Active stack length code D identifies the lamination length used for this version and helps distinguish it from other motors in the same frame family. The tachogenerator is rated as Standard, which suits general motion control duties that do not require ultra-fine spindle feedback. The unit is classified as a motor for analog drives, so it is intended for systems that use analog command signals and tacho return lines instead of digital fieldbus communication.
