Product Description:

The MAC025A-0-WS-3-E/040-A-0 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It operates with analog drives, supplying controllable torque and speed to positioning tables, pick-and-place arms, and other automation axes that rely on analog command voltages. When paired with a compatible amplifier, the unit converts continuous electrical commands into precise mechanical rotation for industrial motion tasks. This type of motor is commonly used where smooth low-speed regulation and repeatable axis response are needed from an analog control loop.

This model is shipped without a blocking brake, so any load-holding requirement must be covered by external mechanisms or constant drive torque. Cooling is handled through natural convection, eliminating the need for fans or external liquid circuits. The power leads exit through a connector on side A, and this fixed interface helps simplify cable routing in compact machines. Electrical characteristics follow the WS winding code, which matches the motor to compatible analog servo amplifiers. The frame uses the compact A motor size, which helps reduce the installed footprint while preserving the magnetic cross-section needed for rated operation.

For feedback and auxiliary coupling, the motor includes tacho feedback and a second shaft end. The tachogenerator provides a proportional speed signal, and the auxiliary shaft allows an additional encoder or mechanical load to be coupled without adapters. That arrangement is useful when a separate measuring device or coupling element must be mounted at the rear of the motor. The 025 designation indicates the axial length, giving the motor a predictable stack size when several axes are arranged close together. Its internal sensors and insulation are intended for legacy ±10 V command structures and servo regulators that process continuous feedback rather than digital control signals.
