Product Description:

The MAC025A-0-WS-3-E/040-D-0/S006 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for integration with analog velocity and current-loop drives where precise speed control is required for positioning tables, pick-and-place axes, or light material-handling stages in industrial automation lines. By converting electrical commands into controlled rotary motion, the unit provides consistent torque and rapid response in compact machinery layouts. This type of motor is typically used where an external drive amplifier performs the regulation tasks and the motor supplies the mechanical output for the axis.

Winding code WS identifies the coil resistance and inductance set, which affects current demand and torque generation in the matched drive system. Frame designation A indicates the smallest housing in the MAC family, while length index 025 indicates the shortest magnetic stack, helping keep inertia low for fast acceleration and deceleration. Heat is removed solely through natural convection, so the mounting position must allow unobstructed airflow around the stator housing. The shaft is supplied without a blocking brake, so loads must be secured by motor torque or a separate mechanical holding method when power is removed. Its compact build also suits machine sections where installation space is limited.

The feedback arrangement combines a tacho feedback generator with a second shaft end. The tachometer produces a proportional voltage that analog drives use for closed-loop speed regulation, and the extra shaft extension permits simultaneous coupling to an external encoder or another mechanical element without interfering with the internal feedback device. Classified as a motor for analog drives, this model works with MAC control platforms that rely on continuous analog signals rather than serial fieldbus communication. That arrangement is useful on existing equipment where the original control structure remains in service and consistent speed feedback is still required.
