Product Description:

The MAC112C-0-KD-2-C/130-A-0/S005 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. As a motor for analog drives, it converts control voltages from servo amplifiers into precise shaft torque and speed for positioning and contouring axes in automated machinery. This operating style supports steady motion control in indexing, feed, and tracking applications where repeatable response is important. Power and feedback connectors sit on side A of the housing, which can simplify cable routing when the motor is mounted with the shaft facing the machine center.

This model has a centering register of 130 mm, which serves as the pilot fit that aligns the housing to the machine frame and helps keep radial runout low. Heat is removed through natural convection, so no external blower or liquid circuit is required and surrounding space can remain less crowded. The rotor has a nominal speed of 1500 rpm, matching older analog velocity loops that expect this base speed. Its electromagnetic layout uses the KD winding code, which corresponds to the resistance and inductance values expected by the matching drive. The motor is supplied without a blocking brake, so holding torque must be provided by the drive or by an external mechanical latch when power is removed.

The position loop relies on speed feedback supplied through tacho feedback, a method that generates a clean voltage proportional to actual motor speed for analog velocity regulators. That signal reaches 3 V/1000 rpm, giving the controller a simple scale factor for setup and adjustment. The motor has a C length, which provides a mid-range stack for general-purpose axes that need a balance between torque and inertia. Its 112 frame code sets the flange and shaft dimensions for compatibility with standard planetary gearboxes. The tacho uses a standard quality grade, which helps provide repeatable speed signals without added linearization circuitry.
