Product Description:

The MAC025A-0-WS-2-E/040-D-0 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for use with external analog servo drives where precise velocity and position regulation are required in automated machinery such as small index tables and light-duty pick-and-place axes. By combining permanent-magnet excitation with armature-controlled current, the unit converts electrical command signals into proportional torque and speed for responsive motion control in industrial automation. Its compact format supports installations where available mounting space is limited and fast response is still required from the rotary axis.

This model removes heat through natural convection, so installation must allow unobstructed airflow along the housing fins and enough surrounding space for heat dissipation. The shaft is supplied without a blocking brake, so any holding torque during power-off must be provided by the machine mechanics or the drive. Motor speed is returned to the controller through tacho feedback, a velocity transducer that generates a voltage proportional to motor speed for analog loop control. The motor uses motor size 025 with motor length A, giving it a compact format suited to light-duty servo axes that need low inertia and stable continuous operation.

The winding designation WS corresponds to phase resistance and inductance values compatible with 60 V class supplies and supports rapid current rise for fast corrections. The unit is a motor for analog drives, so the power stage uses continuous voltage or current references rather than fieldbus commands. A centering diameter of 040 mm helps align the housing on the machine interface, and the connection is arranged on side D for straightforward cable routing. This layout is suitable for compact machines that need accurate speed control, direct drive response, and orderly cable entry around adjacent components.
