Product Description:

The MAC025A-0-WS-4-E/040-B-1/WI670LV is an AC servo motor produced by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. Designed for closed-loop motion axes, this motor delivers torque and speed regulation in analog drive systems that automate packaging lines, pick-and-place gantries, and indexing tables. Its lightweight construction and square-flange interface help keep the installation compact while supporting continuous-duty positioning tasks. It interfaces with external drives through a standardized circular power plug and a dedicated feedback connector.

The winding code WS identifies the stator copper layout and matches the electrical resistance and inductance values expected by the companion drive. Heat produced in the stator is removed through natural convection, so no external blower or liquid circuit is required. Power conductors reach the stator terminals through a connector on side B, allowing straight cable routing along the machine frame. Rotor position is detected by an incremental encoder with standard mounting, which delivers periodic square-wave signals for velocity and position feedback. The motor size of 025 indicates a very compact housing that helps reduce mass and fit installations with limited space.

The compact A length keeps the motor short in the axial direction, which is useful where surrounding components limit available mounting depth. The motor includes a standard blocking brake, enabling the shaft to lock when power is removed. For applications that require a different feedback arrangement, the configuration supports tachofeedback with an incremental or absolute encoder. Its classification as a motor for analog drives means the current loop is handled by the external controller, while the motor’s internal sensors report motion variables without embedded digital processing.
