Product Description:

The MAC112C-0-ED-2-C/130-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive controllers, the unit supplies controlled torque and speed so machine tools, printing presses, and handling modules can execute repeatable motion sequences in an automated line. It is suited for axis duties that require stable speed regulation and consistent motion response during repeated operating cycles.

A centering diameter of 130 mm allows the flange to seat accurately on standard machine frames. Heat produced in the stator is removed by natural convection, so external fans or liquid circuits are not necessary when the enclosure has free airflow. The motor uses a 112 frame, and the ED winding matches the current and voltage characteristics expected by analog amplifiers. Under rated conditions, the rotor reaches 3000 rpm, providing a balance between high linear speed on ball-screw axes and controlled positioning behavior. This arrangement supports use with legacy drive racks that rely on current loops rather than fully digital protocols.

Speed feedback is provided by integral tacho feedback, and its generator supplies 3 V per 1000 rpm so the controller can monitor actual velocity without an external encoder. The C length magnetic stack increases continuous torque compared with shorter versions while keeping rotor inertia moderate for rapid reversals. The unit uses standard tacho quality, which is suitable for velocity regulation in general-purpose machinery. It is supplied without a blocking brake, so applications that must hold a load at standstill need mechanical clamping or drive torque. Power leads exit through a connector on side A of the housing, which helps simplify cable routing when the motor is mounted with the shaft facing the workspace.
