Product Description:

The MAC112C-1-HD-2HC/130-A-0 is a servo motor built by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts electrical energy into controlled rotary motion for positioning and speed-regulated axes in industrial automation. Its type code places it in the medium frame range of the family and indicates a configuration that accommodates an external blower, precise tachometer feedback, and direct interfacing with legacy drive amplifiers. This arrangement suits machines that rely on stable analog servo control rather than encoder-based digital feedback.

The motor reaches a nominal speed of 2000 rpm, which provides a fixed operating point for gear selection and continuous-duty operation. An external blower rated at AC 230 V forces air along the housing fins, keeping the stator iron below its thermal limit during full-load operation. A centering pilot of 130 mm aligns the flange with gearboxes or machine frames and helps minimize radial bearing load. Heat leaves the frame through axial surface cooling, so the motor must remain in an unobstructed airflow path. Power conductors exit through a connector on side A, which can simplify cable routing when the control cabinet is mounted on that side of the machine.

Electrical behavior follows the series’ HD winding code, which corresponds to the resistance and inductance values used by the analog amplifier. A built-in tachogenerator supplies 1.5 V per 1000 rpm, providing a proportional speed signal for closed-loop regulation without digital encoders, and the feedback is classified as standard quality. Dimensional identifiers include motor size 112 and length code C. These values describe the motor envelope and active iron length used when fitting the unit into presses, packaging stations, or material-handling tables.
