Product Description:

The MAC112D-0-ED-3-C/13-A-2/S018 is a brushless AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for closed-loop positioning and velocity control, this motor converts electrical energy from drive amplifiers into controlled mechanical rotation for axes on packaging, printing, or material-handling machinery. Its mechanical and electrical interface matches Indramat motor for analog drives applications, letting the unit fit legacy or mixed-technology automation cells without additional adaptation.

Heat generated in the stator is dissipated through natural convection, so the housing must be mounted where free airflow is available and no external blower is required. The frame follows size code 112, which accommodates medium-torque loads while remaining compatible with standard MAC mounting patterns. Length code D extends the active iron stack, giving higher continuous torque capacity than shorter variants in the same size. Under rated conditions, the rotor reaches 3000 rpm, a speed suitable for camming or indexing tasks that demand fast cycle times without overshooting feedback loop limits. Internal wiring marked by winding code ED indicates the phase resistance and inductance that the analog drive must match for correct current regulation and thermal use.

Position data are returned with tacho feedback and a second shaft end, allowing the connected drive to derive real-time velocity from the tacho generator while an external encoder or mechanical load can couple to the auxiliary shaft. The tacho generator is graded Standard, indicating the linearity and ripple levels expected for general-purpose servo loops. Its calibration factor is 3 V/1000 rpm, so the drive receives three volts of feedback for every thousand revolutions per minute. This makes the feedback scaling easy to apply when the motor is integrated into an existing analog control system.
