Product Description:

The MAC112C-0-ED-4-G/130-B-0/WI520LX/S014 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts voltage commands from legacy drive amplifiers into controlled shaft motion for positioning and velocity regulation in automated equipment. Integrated tachometer and encoder options let the motor close velocity or position loops directly at the machine, making it suitable for assembly lines, packaging modules, and material-handling axes that require continuous duty with quick acceleration.

Mechanically, the stator centers on a 130 mm pilot diameter that aligns the housing to gearboxes or flanges without additional shims. The nominal operating speed reaches 3000 rpm, allowing analog regulators to maintain linear velocity across common load ranges. Heat produced in the windings is removed by natural convection; therefore, the ribbed exterior must remain exposed to ambient airflow. The electromagnetic circuit follows the manufacturer’s ED winding code so that inductance and resistance match the companion drive cards. Incoming three-phase power is delivered through a connector on side B, which keeps cable bends inside cabinets minimal when the shaft faces side A. The lamination stack corresponds to motor length C, giving this variant intermediate torque between the shorter A and longer D designs.

A built-in tachogenerator provides 3 V/1000 rpm for speed feedback, while an incremental encoder mounted in the standard interface reports position for the drive. The frame is identified as motor size 112, which sets the footprint, shaft height, and allowable thermal load in this series. Operation is specified without a blocking brake, which reduces mass and maintenance but requires external holding devices if vertical axes must be secured during power-off.
