Product Description:

The MAC1120-0-E0-3-C/130-A-2/S018 is a rotary actuator built by Bosch Rexroth Indramat and delivered as part of the MAC AC Servo Motors series. Designed for integration with analog velocity and position controllers, the motor converts drive commands into precise shaft movement for packaging lines, transfer systems, and machine tools. Its mechanical outline and electrical interface let it fit into existing MAC installations while providing consistent torque for continuous-duty industrial motion. This format is also useful in equipment that already uses MAC mounting patterns and analog control architecture.

Mechanical alignment is governed by a centering diameter of 130 mm, which positions the stator housing accurately against gearboxes or mounting flanges. Heat generated during cyclic operation leaves the frame through natural convection, so no external blower or liquid circuit is needed. For load holding during downtime or emergency stops, the shaft is secured by a heavy-duty blocking brake that clamps the rotor when the brake coil is de-energized. Position sensing and velocity feedback are supplied through tacho feedback and a second shaft end, enabling analog drives to derive real-time speed error without an additional encoder. This feedback arrangement supports stable speed regulation when load conditions change during operation. Power conductors enter through a connector on side A, which can simplify cable routing when the motor is mounted with the fan end toward the machine frame.

In application, the motor presents itself to the drive as a motor for analog drives, ensuring compatibility with voltage-controlled MAC amplifiers. The unit uses standard tachometer precision, which provides predictable gain settings for velocity loops without specialty calibration. It follows the dimensional conventions of the MAC AC Servo Motors series, allowing it to fit machine layouts already built around this platform. That layout helps preserve shaft alignment, cable access, and control behavior in machines originally designed for earlier MAC motor installations.
