Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI538/S05 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it is installed on machine tools, packaging lines, and other automation axes to translate drive-controller commands into precise rotary motion. By coupling to gearboxes or direct-drive loads, the unit supplies controlled torque and velocity so that positioning loops in the host control system can maintain repeatable paths and cycle times. The feedback arrangement allows the connected amplifier to compare commanded and actual motion continuously, which helps the axis remain stable during acceleration, deceleration, and steady-speed operation.

The mechanical frame follows an IEC layout, and motor size 112 sets the outer envelope for mounting to machinery. Its axial depth uses motor length C, which gives a mid-range build that balances torque capability with compactness. Precise centering on the pilot recess is ensured by a 130 mm centering diameter, helping the shaft stay aligned with coupled loads. The rotor is rated for a nominal speed of 3000 rpm, so drive regulators can use a wide dynamic range without overspeeding the feedback elements. Speed feedback comes from an internal tacho generator that outputs 3 V/1000 rpm, and controllers scale this linear voltage to calculate actual shaft velocity.

Thermal management relies on natural convection, so the motor must be mounted where ambient airflow can carry heat away without auxiliary fans. Power conductors enter through a connector on side A, which can simplify cable routing when the axis is installed in line with adjacent modules. Position information is supplied by an incremental encoder that shares the same mechanical reference as the tachometer, enabling combined velocity and position loops in analog drive hardware. Because there is no blocking brake, holding torque during power-off conditions must be provided by external clamping devices or by maintaining drive current.
