Product Description:

Bosch Rexroth Indramat manufactures the MAC112C-0-KD-3-F/130-A-0 servo motor within the MAC AC Servo Motors series. This model is supplied as a motor for analog drives, so it generates controlled mechanical power when paired with legacy current-controlled amplifiers common in industrial automation. Direct mounting to machine frames allows it to move tooling, transport systems, or auxiliary axes that require repeatable motion. That arrangement lets existing analog platforms keep a compact motor-and-drive structure without adding separate motion hardware at the axis.

A centering diameter of 130 mm positions the housing concentrically on coupling flanges and helps limit radial runout under load. Heat is removed through natural convection, permitting installation in cabinets without forced airflow when the surrounding conditions stay within the series limits. With a nominal shaft speed of 1500 rpm, the motor fits applications that favor moderate operating speed and stable continuous duty. The electromagnetic layout uses the KD winding, which gives the resistance and inductance values expected by the matched drive for stable current regulation. Power conductors enter through a connector on side A, enabling cable routing parallel to the motor body in compact machine spaces.

The housing corresponds to motor size 112, and the C length adds stack height for higher continuous torque without changing the mounting footprint. Because there is no blocking brake, holding torque during power-off must be supplied by the mechanical transmission or an external brake module. Speed feedback to the analog controller relies on a precision tacho generator that outputs 3 V/1000 rpm. The integrated sensor is mounted on a second shaft end, and the assembly provides tacho feedback with a second shaft end for improved response linearity and smooth running. This feedback arrangement also supports stable low-speed regulation during repeated start-stop cycles.
