Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI520/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into precise torque and speed for industrial automation axes such as pick-and-place gantries, indexing tables, and feed rollers. Its electromechanical package is intended for connection to legacy analog amplifiers while still supporting fast response in continuous-duty production. Integrated motor feedback also helps the external drive monitor motion without requiring a separate sensing package.

With a frame size of 112, the unit offers a centering diameter of 130 mm, allowing alignment to standard mounting flanges. At a nominal speed of 3000 rpm, it supports operating ranges commonly used in analog motion systems. The built-in blocking brake delivers 45 Nm of holding torque so vertical or suspended loads remain secure when power is removed. Heat is removed through natural convection, which avoids external fans and keeps machine airflow requirements simple. For wiring, the stator power leads terminate through a connector on side A, which helps route cables toward the drive with less bending at the motor entrance.

The winding code ED indicates electrical values matched to legacy analog amplifiers. Tachofeedback is generated at 3 V/1000 rpm, supporting velocity loops that rely on low-level voltage signals rather than digital serial communication. Position data is provided by an incremental encoder in the standard arrangement for this model, giving resolution suitable for medium-accuracy positioning tasks. The combined tacho and encoder feedback supports steady speed regulation and repeatable position tracking. The standard tacho quality and C-length housing give the rotor inertia a balance suited for moderate load moments. Because a blocking brake is included as standard equipment, no external clamp is required to hold the shaft when the power supply is off.
