Product Description:

The MAC025A-0-WS-4-E/040-A-0/WI671LV/S001 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is an AC permanent-magnet motor designed to translate drive commands into precise shaft rotation for pick-and-place axes, indexing tables, and other motion axes found in industrial automation. With a compact frame and standardized connectors, the motor integrates directly with legacy velocity and position controllers, delivering consistent torque and allowing the machine builder to maintain a closed-loop servo architecture without mechanical transmission losses.

The electromagnetic assembly uses winding code WS, matched to the drive voltage so that rated current is obtained without saturation. The motor has a frame length of A, which keeps the body compact, while its size designation of 025 indicates the mechanical envelope used for light-duty motion axes. Heat produced by copper losses is removed through natural convection; therefore, the housing must remain exposed to ambient airflow instead of being recessed in a sealed compartment. The motor has no blocking brake, so vertical loads must be held by an external brake or active motor torque during standby.

Power enters through a connector on side A, simplifying cable runs in installations where clearance is limited on the opposite side. The feedback interface supports tacho feedback with an incremental or absolute encoder, permitting velocity-loop control or high-resolution positioning, and this model includes an incremental encoder with standard mounting for connection to compatible counting circuits. Because it is classified as a motor for analog drives, its excitation and feedback signals are compatible with ±10 V command interfaces and legacy servo amplifiers used in established production lines. The encoder allows the connected controller to monitor shaft movement and correct positional or speed deviations as operating loads change.
