Product Description:

The MAC025A-0-WS-4-E/040-B-1/WI651LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a servo motor for classic controller-based systems, it converts current commands from velocity or torque controllers into precise rotary motion for positioning tables, feeders, and similar automation axes. It is suited to compact axes that need controlled acceleration and steady low-speed operation. This operating style works well in machines that rely on external control hardware for command processing. The housing, flange pattern, and electrical interfaces follow the dimensional framework common to the MAC platform, so the motor fits equipment built around that series.

The electromagnetic section uses winding code WS, which gives the motor the coil resistance and inductance values associated with this version. Heat is removed through natural convection, so no external blower or liquid cooling circuit is required. Free air circulation around the housing helps carry heat away during operation. The motor uses size 025 with length A, which helps keep inertia low while maintaining responsive motion. Power and feedback cables connect through a connector on side B, which keeps the cable outlet opposite the drive end. That arrangement also helps keep the machine outline compact where mounting space is limited.

For holding loads when power is removed, a standard blocking brake is integrated and releases when energized by the drive. The feedback package provides tacho feedback with incremental or absolute encoder options for speed and position signals. Applications that only need incremental counting can use the channel described as an incremental encoder with standard mounting, which supports closed-loop speed control. The unit is a motor for analog drives, so its electrical and feedback arrangement matches the control architecture used with this motor family. This layout supports speed-regulated motion and positioning tasks in established automation platforms.
