Product Description:

The MAC025A-0-WS-4-E/040-A-1/WI652LX is an AC servo motor built by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. Designed for closed-loop positioning and velocity control, the unit converts electrical power into controlled rotary motion for automated machinery such as packaging equipment, indexing stations, and material-handling axes. It interfaces directly with compatible Indramat drive amplifiers, providing the torque and speed regulation needed for repeatable starts, stops, and continuous motion. This makes it suitable for machines that require steady servo response from a compact motor without adding separate motion hardware at the axis.

The motor is delivered with a standard blocking brake that locks the shaft when power is removed, allowing vertical loads to remain stationary without external clamps. Heat is dissipated by natural convection, so no fan or external cooling air is required and the housing must remain unobstructed for airflow. The motor size is 025, and the compact A length gives a short axial dimension suited to tight machine frames while helping reduce mass and inertia. Electrical power reaches the stator windings through a connector on side A, which places the cable exit at the drive end for direct routing inside the machine enclosure.

The electromagnetic layout uses winding code WS, which indicates the electrical characteristics used with compatible Indramat analog amplifiers. For speed supervision, the motor can be ordered with tacho feedback, an incremental encoder, or an absolute encoder, and this unit uses an incremental encoder with standard mounting. Standard mounting keeps the mechanical interface consistent with other motors in the series and preserves the expected flange arrangement. These feedback signals are processed directly by analog regulators, which matches its classification as a motor for analog drives and supports stable position and speed control without additional fieldbus electronics.
