Product Description:

The MAC112C-0-HD-1-B/130-A-1/I01250 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy drive controllers into controlled shaft rotation and torque for industrial automation equipment such as gantries, presses, and packaging stations. Because the unit integrates position sensing and an electromechanical brake, it supports accurate holding and rapid indexing tasks without external locking devices, making it suitable for medium-inertia axes that require closed-loop speed and position regulation.

The blocking brake rated at 45 Nm secures the shaft when the drive is disabled, preventing back-driving on vertical or unbalanced loads. A centering diameter of 130 mm aligns the stator precisely with machine mounting faces and minimizes radial runout. Heat is removed through natural convection, so no external fan or liquid circuit is required, but installation must allow free airflow around the housing. Motion feedback is generated by an incremental encoder, which supplies differential signals to the controller for fine speed and position loops. Under continuous duty, the rotor can reach a nominal speed of 2000 rpm, matching the velocity range of typical mid-power mechanical transmissions. An integrated tacho generator outputs 3 V/1000 rpm, giving an analog velocity reference that legacy analog amplifiers can use for closed-loop regulation.

The axial build is identified by length code C, giving a stack height that balances torque output and installation depth. Frame size 112 refers to the stator outside diameter and pairs the unit with mounting hardware sized for this class. Power conductors terminate in a connector on side A, keeping cables on the drive end of the axis and simplifying service access. Electrical characteristics are indicated by winding code HD, which uses a turn set selected for the required voltage-to-current relationship so the motor can be paired with matching analog drive modules.
