Product Description:

Bosch Rexroth Indramat manufactures the MAC112D-0-FD-4-C/130-A-0/WI574LV as part of its MAC AC Servo Motors series. This motor is intended for analog drive systems where tight velocity regulation is required in industrial automation. It serves as the electromechanical actuator in positioning axes, converting drive output into mechanical rotation for machine tools, packaging lines, and material-handling equipment. Its feedback arrangement also supports closed-loop operation with legacy analog servo electronics.

The rotor seats on a centering flange diameter of 130 mm, a dimension that aligns the housing with precision mounting surfaces. Heat is removed by natural convection, so no external blower or liquid circuit is required as long as surrounding airflow is adequate. The stator uses winding code FD, which identifies the electrical winding layout used within the MAC family. Under rated excitation, the motor reaches 2000 rpm as its nominal speed, making it suitable for medium-speed axes that require smooth velocity loops. The three-phase power leads exit through a connector on side A, which helps simplify cable routing inside the cabinet. Motor length is coded D, giving a mid-range stack height that balances torque and inertia for general-purpose tasks.

The motor has no blocking brake, so stationary holding torque must be provided by the drive or by an external clamp when power is removed. Tachometer feedback is rated at 3 V/1000 rpm, and the tacho quality is standard for analog velocity loops. For position control, the motor uses tacho feedback, an incremental or absolute encoder, and standard encoder mounting to deliver speed and position signals to the controller. This arrangement lets the control system receive motion data without separate external feedback devices. The motor frame follows size code 112, and its classification as a motor for analog drives matches legacy drive cards still used in mature production cells.
