Product Description:
Bosch Rexroth Indramat manufactures the MAC112D-0-FD-4-C/180-A-1/WI520LV/S011, an AC servo motor in the MAC AC Servo Motors series. Intended for analog drive systems, it converts controlled current into regulated mechanical rotation for axes such as positioning tables, tool changers, and material-handling gantries. The unit follows IEC flange dimensions, allowing it to fit machine layouts built around the same frame class. Its configuration suits equipment that uses a separate drive amplifier and external feedback processing for repeatable motion control in industrial automation lines.
The motor includes a blocking brake that delivers 45 Nm of holding torque so vertical or high-inertia loads remain fixed when power is removed. A centering diameter of 180 mm aligns the housing accurately on the machine faceplate, helping maintain shaft concentricity during installation. Thermal energy is dissipated through natural convection, removing the need for fans and simplifying surrounding airflow requirements. The rated nominal speed is 2000 rpm, providing a balance between dynamic response and manageable gearing. Electrical behavior follows winding code FD, which sets the resistance and inductance values used by compatible MAC power stages during continuous duty.
Power is routed through a connector on side A of the stator housing, reducing cable bends inside the enclosure. The shaft carries a DIN 6885 keyway, enabling direct coupling to pulleys or gearboxes without secondary machining. Position data comes from an incremental encoder mounted with a tachogenerator, and the tacho outputs 3 V/1000 rpm for classic analog velocity loops. With frame size 112 and length code D, the motor fits mid-frame installations that need solid torque in a moderate housing size. The standard tacho arrangement also supports established analog control systems used on existing machinery and retrofit applications.
