Product Description:

The MAC112D-0-FD-3-C/180-B-0/S011 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts current-controlled commands from the drive amplifier into regulated rotary motion for positioning, traversing, and speed control in industrial machinery. Its mechanical interface and electrical layout follow the established MAC platform used in many automated systems. This arrangement suits feed axes, transfer mechanisms, and other applications that rely on stable analog speed regulation and repeatable motion over long operating cycles.

A centering diameter of 180 mm guides the housing into the machine flange and helps keep the stator concentric with the load. Heat is removed through natural convection, so no external fan or liquid circuit is required, although free airflow around the finned frame is still necessary. The motor includes tacho feedback and a second shaft end, which provides an analog velocity signal and an additional mechanical interface for auxiliary components. The 112 frame code indicates the motor size used for this housing. The rotor has a nominal speed of 2000 rpm, which supports a practical balance between dynamic response and bearing life. For power wiring, the motor uses a connector on side B, which helps route the supply cable from the rear of the installation.

The elongated D-length housing increases active motor length without enlarging the mounting footprint. The unit is supplied without a blocking brake, making it suitable for axes that remain energized or use a separate holding device at rest. In applications with suspended loads, holding force must come from the drive or from an external mechanical restraint when power is removed. Standard tacho quality keeps the speed signal within the operating range expected by analog regulators, and its calibration of 3 V/1000 rpm matches typical drive input scaling. The FD winding code indicates the electrical characteristics used by compatible drives for rated current delivery across the speed range.
