Product Description:

The MAC112C-1-HD-4-C/130-A-1/W1572LV is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Engineered for analog drives, it converts commanded current into controlled rotary motion for machine axes in automated equipment. With frame size 112 and length code C, the unit suits medium-to-large axes while fitting a standardized mounting layout. A standard blocking brake is integrated so stationary loads remain secure when the drive is disabled. This arrangement makes the motor suitable for positioning and speed-regulated tasks that require stable holding at standstill.

The blocking brake applies a holding torque of 45 Nm, allowing the shaft to resist back-driving from gravity or process forces. Thermal management relies on axial surface cooling assisted by an external blower that operates at AC 230 V, moving air along the housing to remove heat from the stator laminations. Mechanical centering is provided by a 130 mm pilot diameter that aligns the flange accurately to the machine frame and helps keep radial runout low. During continuous operation, the rotor can reach a nominal speed of 2000 rpm, which provides a practical balance between output speed and controllability. This cooling method also supports stable operation during extended duty cycles.

Position and velocity feedback are delivered through tachofeedback with an incremental or absolute encoder, enabling the analog drive to close both speed and position loops accurately. Tachometer output is calibrated at 3 V/1000 rpm, giving the controller a predictable voltage-to-speed relationship during normal operation. Power conductors enter through a connector on side A, which can simplify cable routing where cabinet space is limited. The HD winding supports higher current capability for applications that require sustained servo performance. This feedback arrangement also helps the drive respond smoothly to changing load conditions.
