Product Description:
The MAC112D-1-ED-2HC/180-B-0/S011 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts drive controller commands into precise shaft motion that supports positioning, contouring, and feed duties in industrial automation cells. Its design suits machines that require repeatable speed regulation and smooth response during frequent starts, stops, and direction changes. This type of motor is commonly paired with servo amplifiers that use closed-loop feedback to correct load-related speed variation during operation.
This model uses a blower rated at AC 230 V, and that supply powers the external fan that forces air along the housing. Cooling is provided by axial surface cooling, which removes heat from the stator laminations and helps the motor maintain output during continuous operation. Because the fan is independent of shaft rotation, airflow remains available even when the axis runs slowly or pauses frequently. A centering diameter of 180 mm provides the reference surface that aligns the motor on its mounting pilot for consistent shaft concentricity with gearboxes or couplings. The motor has a nominal speed of 3000 rpm, and the integrated tacho generator delivers 1.5 V/1000 rpm for proportional speed feedback to the controller.
Mechanical holding must be provided externally because the motor has no blocking brake. Instead, velocity information is returned through built-in tacho feedback, which works with the drive's analog control loop during standstill and dynamic operation. The ED winding code sets the electrical characteristics used with matching drive amplifiers for the 112-frame stator. Power conductors exit through a connector on side B, which can simplify cable routing when side A faces the load. Where the axis must remain fixed after power is removed, a separate holding method is required. Additional dimensional data include motor length D and frame size 112, which helps keep installation layouts consistent within this motor platform.
