Product Description:

The MAC112C-0-HD-4-C/130-A-2/WJ520LX/S018 is an AC servo motor produced by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Intended for analog drives, it converts electrical drive commands into controlled rotary motion for positioning and speed-regulated tasks on automated machinery. Integrated speed feedback supports closed-loop operation without external transducers, which helps the motor maintain repeatable shaft motion during changing load conditions. Because the motor combines actuation and feedback in one housing, the connected drive can regulate motion directly while reducing the need for separate sensing hardware. This layout suits machine tools, handling equipment, and other systems that require stable response during starts, stops, and continuous operation.

The electromagnetic package uses the HD winding code, which matches the stator design to drive modules intended for higher current density. Under rated conditions, the rotor reaches 2000 rpm. When line power is removed, a brake rated at 60 Nm clamps the shaft so loaded axes can remain in place during power loss or unexpected shutdowns. A 130 mm centering diameter aligns the flange with gearboxes or machine frames and helps maintain accurate mounting. This alignment also supports consistent coupling position at the machine interface. Heat is removed by natural convection, so the installation should leave open airflow around the housing.

Mechanical holding is provided by a heavy-duty blocking brake that engages automatically when drive voltage drops, which is useful on vertical or suspended axes. For speed supervision, the tacho generator outputs 3 V/1000 rpm, giving the controller an analog signal proportional to shaft velocity, and the feedback channel can also support finer position sensing. Power conductors connect through a connector on side A, which can simplify cable routing where cabinet space is limited. The motor uses motor size 112 with length code C, providing the active section associated with this frame format. That frame arrangement supports a balance between torque capability and installation space for direct machine mounting.
