Product Description:

The MAC112C-2-KD-4-C/130-A-07W1520/S05 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed as a motor for analog drives, it translates ±10 V command signals from legacy servo amplifiers into controlled torque and speed, making it suitable for material-handling axes, feed drives, and other motion loops that still rely on analog interface technology. Tachometer feedback is present, and it can be combined with incremental or absolute encoders for position loops. This allows the motor to work in systems that need both speed feedback and external position evaluation without changing the basic analog drive structure.

This model is equipped with a blower that runs on 115 V AC, so forced airflow is available whenever the motor is energized. A centering diameter of 130 mm aligns the housing with machine frames for repeatable concentric mounting. Heat is removed by axial surface cooling, allowing continuous operation at the rated load without exceeding winding temperature limits. Because the blower provides forced airflow, cooling does not depend only on shaft rotation, which helps during low-speed operation. The nominal shaft speed reaches 1500 rpm, so the motor can run at its rated operating speed when the connected drive supplies rated current. Power leads exit through a connector on side A, so cabling can be routed toward the drive cabinet without crossing neighboring mechanisms. The motor is supplied without a blocking brake, which means holding torque must be provided by the external drive or a mechanical lock when power is removed.

The tacho produces 3 V/1000 rpm, supplying a speed-proportional voltage to the controller while maintaining standard tacho quality for ripple and linearity. The winding code is KD, which identifies the electrical winding used in this motor. The motor has a 112 frame size and a C motor length. This combination fits the MAC-series mounting pattern used by matching machine interfaces.
