Product Description:

The MAC112D-0-ED-4-C/180-A-0/WI520LV/S011 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is specified as a motor for analog drives, meaning it receives ±10 V speed or current commands rather than digital bus data. By converting those commands into controlled rotation, it serves positioning tables, tool changers, and packaging lines that rely on tight velocity regulation. Within a closed-loop system, the unit forms the electromechanical side of the axis, while separate drive electronics handle power switching and protection.

Its centering pilot measures 180 mm, giving precise concentric alignment between the motor and machine frame. Heat produced in the stator is dispersed by natural convection, so mounting clearances must permit vertical airflow. The stator carries winding code ED, which identifies the electrical characteristics used for correct current regulation. During continuous operation, the rotor can maintain 3000 rpm, a speed that supports medium-inertia loads without gearbox multiplication. The motor has no blocking brake, so external holding measures are required when static torque must be maintained. Supply cabling enters through a connector on side A, and the feedback harness accommodates tacho feedback plus incremental or absolute encoder signals.

Mechanical coupling is provided by a DIN 6885 keyway, allowing standard hubs to transfer torque without custom machining. The frame corresponds to size 112, while length class D keeps the motor suited to applications where installation space and suspended load matter. For speed feedback, the internal tacho generator yields 3 V/1000 rpm, and an incremental encoder with standard mounting supplies position data to the analog drive controller. These feedback signals allow the controller to monitor shaft speed and position during operation without requiring a separate external sensing package.
