Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI673LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for closed-loop motion duties, the unit converts drive commands into precise shaft rotation so analog speed and position controllers can coordinate automated axes. Its compact housing is suitable for packaging stations, pick-and-place tables, indexing conveyors, and other machinery that requires repeatable motion with low mechanical mass. The motor uses permanent-magnet excitation to provide responsive torque as the connected drive regulates shaft speed and position.

The rotor is supplied with no blocking brake, so stationary loads must be held by drive-applied torque or an external mechanical device. Heat from winding losses dissipates through natural convection, eliminating the need for forced-air channels, fans, or liquid cooling circuits. The motor has frame size 025 and motor length B, producing a short housing that supports installation where axial space is limited. Power conductors enter through a connector on side B, allowing the cable to follow the machine layout without crossing the output shaft area. Appropriate clearance around the housing helps convection airflow carry heat away during operation.

Signal handling uses tacho feedback to provide the speed information required by the external controller. Because the unit is a motor for analog drives, its feedback signals are compatible with current- or voltage-command control stages commonly used in established automation systems. Position information is supplied by an incremental encoder with standard mounting, enabling the controller to track shaft movement and correct positioning errors during each motion cycle. The encoder produces incremental position data, while the tacho channel provides a continuous velocity signal for stable speed regulation. Both feedback paths allow the drive to respond to changing loads while maintaining controlled acceleration, deceleration, and positioning performance.
