Product Description:

The MAC112A-0-LD-3-C/130-B-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts controlled current from classic MAC amplifiers into repeatable torque for indexing tables, transfer lines, and packaging axes. The motor includes tacho feedback and a second shaft end, allowing the controller to read real-time speed while leaving a mechanical interface available for encoders, brakes, or belt pulleys. Its construction follows established IEC mounting dimensions, which support mounting compatibility with other MAC family frames.

The motor uses a centering diameter of 130 mm, allowing alignment with gearboxes and flange couplings that share this bore. Heat is removed solely through natural convection, so no external blower or liquid loop is required, and installation should permit free airflow around the housing. Under rated excitation, the rotor reaches 3000 rpm, supplying high peripheral speed to directly driven applications before mechanical resonance becomes critical. Electromagnetic behavior is set by winding code LD, which indicates phase resistance and current targets compatible with legacy MAC converters. For wiring, power terminals exit through a connector on side B, keeping the cable bundle away from the primary shaft workspace.

For holding functions, the motor has no blocking brake, so machinery that must remain stationary after power loss requires an external lock or drive-applied holding torque. Speed feedback is provided by a tachogenerator that outputs 3 V/1000 rpm, and its standard tacho quality supports general-purpose regulation. The frame corresponds to size 112, and the axial build matches length code A. This combination provides a balanced relationship between torque capability and overall motor length.
