Product Description:

The MAC025C-0-QS-4-E/040-A-0/WI673LV is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Built as a motor for analog drives, it converts drive current into controlled rotary motion for positioning, indexing, and speed-regulated axes in automated machinery. By accepting analog velocity and torque commands, the unit integrates with legacy and retrofit drive amplifiers and provides precise closed-loop motion where digital fieldbus communication is not required. Its compact frame is sized for light to medium duty tasks such as small pick-and-place manipulators, compact transfer units, or labeling stations.

This motor is supplied without a blocking brake, so vertical loads must be held by external mechanics or maintained drive torque when power is removed. Heat is removed through natural convection, meaning the housing dissipates loss energy into ambient air without forced airflow or liquid circuits. The electromagnetic stack uses motor length 025, giving a short active core that helps limit inertia and support quick acceleration. The frame size is motor size C, which uses the flange pattern and shaft height associated with this MAC frame. Power conductors exit through a connector on side A, which helps determine cable routing in tight installations.

The motor also supports combined feedback devices for analog control. A built-in tacho feedback element supplies an analog speed signal, while the mounted incremental encoder supplies digital position pulses for the controller’s velocity and position loops. This dual-channel arrangement allows stable regulation across the speed range, and either feedback source can be used as the primary reference by the analog controller. The motor belongs to the MAC AC Servo Motors series, so its hall sensors, pin assignments, and mechanical tolerances match other MAC models in the same product line.
