Product Description:

The MAC112C-0-KD-2-C/130-B-0/S005 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, this unit converts command voltages from legacy controllers into regulated torque and speed for positioning tables, presses, or handling axes on the factory floor. The motor integrates a DC tachogenerator so the connected drive can close a speed loop without an external encoder. This arrangement suits established motion systems that continue to use analog control rather than digital networked drives.

Mechanical dimensions and thermal behavior determine how the motor fits and performs. A centering diameter of 130 mm aligns the flange with gearboxes or mounting plates, while frame size 112 gives the motor an outline consistent with other units in the MAC family. Winding code KD indicates the wire gauge and turns count used for the motor, which affects the current constants seen by the drive. Under rated conditions, the rotor reaches 1500 rpm, a speed suited to machines that favor high torque at modest shaft speed. Heat is removed by natural convection, which eliminates the need for forced air or liquid cooling and helps keep the installation straightforward.

Electrical connection and feedback complete the integration details. The three-phase power leads exit through a connector on side B, so cable routing stays clear of the driven load when the shaft is on side A. Speed information comes from the integrated tacho feedback, and the generator supplies a proportional signal of 3 V/1000 rpm that the analog drive processes directly. Because the motor has no blocking brake, vertical axes must be secured by static torque or external clamps during shutdown. The motor also has a C length code, which gives it the corresponding housing length for this frame size.
