Product Description:

The MAC025C-0-QS-4-E/040-B-1/WI671LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for industrial automation, the unit operates as a torque and speed actuator when paired with analog controllers, delivering closed-loop motion to packaging, printing, and assembly equipment. By converting drive output into regulated shaft rotation, it supports programmed indexing, tensioning, and positioning routines. Its compact format suits machines that need responsive motion without adding unnecessary mechanical bulk. This makes it suitable for repeatable start-stop cycles and steady speed regulation in compact machinery.

Thermal management relies on natural convection, so airflow around the housing must stay unobstructed to maintain winding temperature within normal limits. A standard blocking brake holds the rotor when the amplifier is disabled, helping prevent back-driving on suspended or inclined loads. The power conductors enter through a connector on side B, which helps keep cable routing orderly in narrow machine enclosures. The motor uses a size C frame, and the electromagnetic stack corresponds to the 025 motor length code. This combination gives the unit a compact mounting footprint suited to medium-duty axes.

Position feedback is furnished by an incremental encoder mounted at the rear, providing differential channels for speed monitoring and phase alignment. These encoder signals help the paired amplifier maintain commutation and stable low-speed behavior during controlled motion. Classified as a motor for analog drives, the model interfaces with current-loop or velocity-loop amplifiers rather than digital fieldbus controllers. This arrangement suits equipment that uses conventional analog servo architecture and requires consistent rotary feedback.
