Product Description:

The MAC025A-0-WS-4-E/040-A-0/WI671LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as the motion-producing element in axes driven by analog amplifiers, converting commanded electrical input into controlled shaft rotation for machine tools, pick-and-place units, and conveyor sections. This operating role helps automated equipment maintain repeatable positioning and steady cycle timing during continuous production. In typical service, the paired drive regulates current to control acceleration, deceleration, and running speed throughout repeated motion cycles.

The winding code WS identifies the electrical winding arrangement used in this motor, which supports proper matching with compatible drive current characteristics. The motor uses size 025 with the compact A length, which keeps inertia low and helps the axis respond quickly to changing commands. Heat is removed by natural convection, so no separate blower or liquid circuit is required. Power conductors terminate on a connector on side A, which helps keep cable routing straightforward in confined machine layouts and supports cleaner installation around nearby components.

The motor has no holding brake, so the load must be retained by external means whenever drive torque is unavailable. Rotor position is provided by an incremental encoder with standard mounting, and the feedback arrangement is described as tachofeedback incremental or absolute encoder, indicating compatibility with systems that use tachometer signals together with position feedback. The unit is classified as a motor for analog drives, indicating compatibility with analog control architectures rather than fully digital fieldbus platforms. This feedback and control arrangement fits existing analog motion systems that require stable response and consistent signal handling during routine operation.
