Product Description:

Bosch Rexroth Indramat manufactures the MAC112C-0-HD-3-C/130-A-1/S005, a servo motor in the MAC AC Servo Motors series. Classified as a motor for analog drives, it is used in automation axes where precise velocity loops are implemented through analog command voltages. The motor converts electrical energy into controlled mechanical rotation for positioning or continuous-duty tasks in production cells. It can be used in indexing tables, feed drives, and similar machine functions that depend on stable speed regulation.

The motor is equipped with a standard blocking brake that provides 45 Nm of holding torque, allowing load-holding axes to remain stationary when power is removed. This brake is useful on vertical axes and other applications where drift after shutdown is not acceptable. A centering diameter of 130 mm aligns the housing in machine frames and helps maintain concentric shaft placement. Heat produced by copper losses is dissipated through natural convection, so no external blower or coolant lines are required. The stator winding supports rated speed regulation up to 2000 rpm, and a molded connector on side A provides the power interface. A built-in tacho generator outputs 3 V/1000 rpm, giving analog velocity feedback that matches legacy drive controllers.

Winding code HD matches the phase resistance and inductance to compatible analog drive amplifiers used in the MAC series. The motor has a frame size of 112, which provides the stator iron volume and shaft diameter used in mid-range production machinery. A rear shaft extension connects directly to the integrated tacho feedback, allowing the drive electronics to measure speed without an external encoder. This arrangement avoids the need for a separate external speed pickup in systems built around analog feedback. The length code C keeps the installation depth moderate where available clearance is limited.
