Product Description:

The MAC025A-0-WS-3-E/040-A-1 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is built as a drive element for positioning or velocity-controlled axes that rely on analog command signals. In service, it converts commanded electrical input into controlled rotary motion for feed axes, handling units, and synchronized machine movements. This allows machine tools, printing lines, and material-handling modules to maintain repeatable motion profiles during normal operation.

This motor is cooled by natural convection, so heat is removed through the housing surface without forced airflow. That arrangement is useful when cabinet space or noise limits rule out fans, and it also keeps the installation free of auxiliary cooling hardware. Its mechanical form factor combines size A with a length of 025, giving it a short overall body while preserving the torque associated with the series. Power conductors connect through a connector on side A, and the electromagnetic characteristics follow the WS winding code, which indicates coil resistance and inductance values used by matched analog amplifiers.

A standard blocking brake is integrated to hold the shaft when the drive is disabled, maintaining position on vertical or suspended loads without external clamps. Position feedback is handled by tacho feedback and a second shaft end; the tachogenerator supplies real-time speed data, and the auxiliary shaft end allows an additional encoder to be fitted when higher resolution is needed. Classified as a motor for analog drives, it accepts ±10 V speed or torque references instead of fieldbus commands, which suits legacy control racks still used in processing equipment. The motor uses interchangeable connectors, standard mounting flanges, and sealed construction used across the MAC series.
