Product Description:

The MAC025B-0-ZS-4-E/040-B-1/WI673LV/S001 is a servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It delivers controlled torque and speed for indexing tables, small actuators, and other compact motion axes used in automated machinery. By combining an AC stator design with electronic feedback, the unit converts drive commands into precise shaft movement for closed-loop motion control. This makes it suitable for applications where repeatable positioning and stable speed regulation are required during continuous machine operation.

The motor relies on natural convection for cooling, so no external fan or liquid circuit is required when adequate airflow is available around the housing. It uses size code 025 and frame length B, which gives the unit a compact form suited to light loads and quick acceleration. Power is routed through a connector on side B, placing the supply connection at the rear of the motor. This layout helps keep the power lead separated from the feedback connection and can make cable routing more orderly inside a machine enclosure. The compact housing also helps the motor fit into installations where available mounting space is limited.

A standard blocking brake is integrated to hold the shaft when the drive is disabled, which helps prevent back-driving on vertical or suspended axes. The unit is a motor for analog drives, so it is intended for use with legacy amplifiers that regulate current through ±10 V reference signals rather than digital fieldbus control. Feedback is provided by an incremental encoder with standard mounting, allowing the drive to monitor shaft position and speed without an additional external sensor. This arrangement supports controlled stopping, repeatable positioning, and stable operation in machines that continue to use analog servo control architecture.
