Product Description:

The MAC112C-0-HD-4-C/130-A-0/WI520LV/S005 AC servo motor is built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts command voltages from classic amplifier cards into controlled rotary motion for positioning, indexing, and speed-control tasks in automated machinery. This type of motor is well suited to axes that require stable rotary response and consistent speed regulation during repeated motion cycles. Its feedback arrangement also supports applications that need predictable performance at low and moderate shaft speeds.

The motor has a frame size of 112, which sets its mounting footprint and shaft height within the series. A centering diameter of 130 mm aligns the flange on machine plates and helps maintain concentricity in the drive train. The winding code HD identifies the coil arrangement used for this motor and matches drives with higher current capability. Under rated load, the rotor reaches 2000 rpm, allowing feed axes to follow moderate-speed motion profiles without added gearing. For velocity feedback, the tacho generator delivers 3 V/1000 rpm, giving the analog controller a linear signal for comparing commanded and actual speed.

Cooling is done by natural convection, so the housing dissipates heat without an external blower and installation space should allow free airflow. The output shaft uses a DIN 6885 keyway for direct connection to pulleys or gear hubs, and the motor has a connector on side A to keep cabling on the drive end. An incremental encoder can return position data through the standard interface, while an optional absolute encoder can use the same tachofeedback channel. The motor is supplied without a blocking brake, so any vertical load must be held by external hardware or drive torque when power is removed. The C length keeps the overall motor depth moderate for machine layouts with limited installation space.
