Product Description:

The MAC112D-0-ED-4-C/130-A-0 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive controllers, it converts commanded current into controlled rotary motion for positioning, indexing, and tensioning tasks in automated equipment. The D-length housing provides a longer active stack for higher continuous torque while keeping the same mounting geometry used for this frame size. Its operating profile suits machines that rely on smooth velocity control and predictable response during frequent starts and stops.

With a centering diameter of 130 mm, the housing seats accurately in pilot bores to help reduce radial runout at the machine interface. The shaft has a nominal speed of 3000 rpm, which suits many common gearbox ratios used in packaging, printing, and handling equipment. Thermal losses are dissipated by natural convection, so the installation does not require a separate fan or liquid circuit. The stator uses winding code ED, which corresponds to electrical characteristics matched to standard analog amplifiers. Electrical connection is made through a connector on side A, which keeps motor leads routed in one direction and can simplify cable placement in compact machine sections.

This frame is supplied without a blocking brake, so a parked axis must rely on drive torque or external holding hardware when power is removed. Feedback is provided by an incremental or absolute encoder with tachofeedback, giving the controller signal information for closed-loop speed or position control. The tacho generator produces 3 V/1000 rpm, which supplies a proportional speed signal to the drive. The assembly follows the dimensions of motor size 112, placing it in a mid-range format suited to packaging, printing, and material-handling axes that need stable response over long operating periods. This arrangement is useful where the axis must maintain consistent motion during changing process loads.
