Product Description:

The MAC112C-0-HD-2-C/180-A-0/S03 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended to work with analog drive controllers, the unit converts current commands into proportional torque and speed for automated machinery such as tool changers, gantry axes, and material-handling stations. Its design pairs a permanent-magnet rotor with electrical windings selected for medium-inertia applications, providing a stable response across a broad load range while keeping the associated control hardware simple.

The HD winding code indicates that the motor’s electromechanical characteristics are matched to drives that supply higher current at moderate voltage, allowing full torque to be reached quickly. A nominal speed of 2000 rpm establishes the operating point that the speed regulator tracks during steady-state production. Heat developed in the stator is removed through natural convection, eliminating the need for external fans and simplifying enclosure layouts. Mounting surfaces align through a 180 mm centering diameter, providing consistent concentricity between the shaft and connected gearboxes. For velocity feedback, the integrated tacho generates 3 V/1000 rpm, providing a linear signal that analog amplifiers can scale without additional conditioning.

The built-in tacho feedback circuit provides a stable speed signal during prolonged operation. Installation is simplified because the power conductors exit through a connector on side A, keeping cable trays on one face of the machine frame. The motor has a 112 frame size and a frame length of C, so its rotor inertia and shaft height correspond to common European servo layouts. The unit is supplied without a blocking brake, allowing free rotation when power is removed and preventing residual drag in applications that already use external clamping devices.
