Product Description:

The MAC025C-0-QS-4-E/040-A-0/WI670LV/S006 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. As a motor for analog drive controllers, it converts command voltages from legacy positioning amplifiers into precisely regulated shaft torque and speed. Feedback signals allow the connected control system to regulate motion accurately in machine tools, handling robots, and printing lines under variable mechanical loads. That operating role makes it suitable for axes that require smooth speed regulation and repeatable positioning rather than simple on-off motor control.

Within the MAC AC Servo Motors portfolio, this model is built in the medium-frame size C, a housing dimension that balances magnetic torque density with installation space. Its stator stack height is identified by length 025, indicating a relatively short active core for low inertia applications that need fast acceleration. Heat is removed by natural convection, so no fan or liquid circuit is attached and the motor can be installed without auxiliary cooling hardware. The compact active core helps support quick response during frequent start-stop cycles. Power conductors exit through a single connector on side A, which helps simplify cable routing when the motor is mounted to gearboxes or linear stages.

The shaft is supplied without a blocking brake, so any static holding force must be provided by external clamping or drive current when the machine is idle. For velocity and position feedback, the motor can work with an incremental or absolute encoder, while the flange carries an incremental encoder with standard mounting as its primary feedback option. These signal formats integrate directly with analog servo amplifiers and support closed-loop regulation in equipment that predates fieldbus control. Because it is optimized for analog drives, the unit is well suited for retrofit installations that retain the existing control topology.
