Product Description:

The MAC112D-2-HD-4-C/130-B-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it supplies controlled torque and speed to automation axes such as material-handling gantries, packaging machinery, and printing stations. Its electromechanical construction supports closed-loop regulation with external drive electronics, allowing stable response during positioning, indexing, and speed-controlled operation in continuous-duty industrial service.

The motor uses frame size 112 and housing length code D, which place it in a larger format within the series and support higher torque output for demanding axes. A centering diameter of 130 mm provides accurate shaft alignment against driven equipment and helps maintain consistent mounting geometry. Under rated excitation, the rotor reaches 1500 rpm, offering a balanced compromise between inertia and available output power for medium-speed tasks. Heat generated in the stator windings is removed by axial surface cooling, and an auxiliary blower can be fitted to maintain airflow across the fins. These thermal and dimensional features work with winding code HD so the copper fill, resistance, and inductance match the current capability of analog power stages.

The external blower operates on AC 115 V, supplying the airflow required by the cooling scheme. Position and velocity signals are derived through an incremental or absolute encoder with tacho feedback, enabling the analog controller to select either velocity-loop or position-loop operation according to the needs of the axis. Speed feedback is proportional to shaft speed at 3 V/1000 rpm, and the tacho has standard accuracy for routine drive tuning and steady regulation. The unit is supplied without a blocking brake, so holding torque must be provided by the drive or by mechanical locks when the axis is at rest. Power conductors are routed through a connector on side B to simplify cable routing in installations that use this connection direction.
