Product Description:

The MAC025C-0-QS-4-E/040-A-1/WI651LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as the rotary actuator in analog-controlled positioning axes, converting regulated current into precise shaft rotation for feeders, indexers, and compact handling modules. The motor interfaces directly with legacy amplifier families and supplies tightly regulated torque and speed for closed-loop motion sequences used throughout industrial automation cells.

Thermal management relies on natural convection, so no forced-air or liquid cooling hardware is required. This cooling method keeps the housing simple and avoids the need for separate airflow components around the motor. A standard blocking brake locks the rotor when power is removed, securing vertical or load-holding stations. The designation motor size C sets the mounting geometry for machines built around this frame pattern. Power enters through a connector on side A, placing the mains lead on the drive-end face for easier routing in tight cabinets. Position feedback versatility is provided by an incremental or absolute encoder with tacho feedback, which supplies either velocity-proportional signals or digital counts to the control loop. It is electrically compatible with TDM, KDS, and related analog servo drives, allowing integration with legacy control hardware.

The code motor length 025 indicates the shortest stator stack available in this frame, which helps reduce inertia for rapid start-stop cycles on light loads. Classified as a motor for analog drives, it accepts ±10 V command references instead of digital fieldbus traffic, simplifying retrofits in established equipment. That signal scheme supports existing analog control loops without requiring a digital communications network. Where high-resolution position capture is needed, the unit can use an incremental encoder with standard mounting, keeping the sensor body within the housing outline and avoiding extra envelope depth. This internal mounting helps preserve rear clearance where nearby panels or cable ducts limit available space.
