Product Description:

The MAC112C-0-KD-3-C/130-A-0/S05 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it accepts proportional voltage or current references from legacy drive amplifiers and converts them into precise torque and speed for automated axes. This arrangement lets machine tools, packaging stations, and material-handling systems keep closed-loop motion on existing analog control platforms without requiring a full drive-system redesign. It is suited to applications where stable speed regulation and repeatable positioning are handled by established analog control hardware.

The motor has a centering diameter of 130 mm, which helps align the flange accurately with adjoining mechanical mounts. The stator uses the KD winding, which gives the electrical constants expected by the matching drive. Nominal rotor speed is 1500 rpm, providing a baseline for velocity control through the built-in tacho. Heat is removed by natural convection, so airflow around the housing should remain unobstructed during operation. Because the motor is supplied without a blocking brake, any static load must be held by drive torque or an external mechanical latch. The built-in tachogenerator supplies 3 V per 1000 rpm as a standard analog feedback signal for the amplifier.

Dual-purpose feedback is provided through tacho feedback and a second shaft end, which allows speed measurement while leaving an auxiliary shaft face available for an added coupling or encoder. The housing uses size 112 and length C, giving the motor an extended frame for mid-range load applications. Mains conductors attach through a connector on side A, which helps keep cable routing parallel to the motor body. This layout can simplify installation where wiring must stay clear of adjacent moving parts. The second shaft end also gives more flexibility when external feedback or accessory components need to be mounted without changing the main output arrangement.
