Product Description:

The MAC025C-0-QS-4-E/040-B-1/WI670LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for use with analog drive amplifiers, it converts electrical commands into precise shaft rotation for coordinated motion in industrial automation equipment such as pick-and-place heads, indexing tables, and print cylinders. Its feedback arrangement supports closed-loop speed regulation, which helps motion systems maintain stable response with minimal signal delay. This motor is suited to applications that need accurate rotation, repeatable speed control, and compact installation on smaller machine axes.

The motor uses frame size C and a centering diameter of 40 mm, giving it a compact mounting interface for space-limited equipment. Length code 025 indicates the active magnetic stack used for the motor’s continuous output range. Heat is removed by natural convection, so the housing surface should remain exposed to ambient air for proper cooling. This cooling method avoids the need for an external fan and helps keep the installation simple. The power connector is located on side B, which routes incoming conductors away from the drive end in inline machine layouts.

Motion feedback is supplied by an incremental encoder, which provides position-related signals for the analog drive and supports accurate velocity control. The motor is equipped with a blocking brake that engages when supply voltage is removed, helping prevent back-driving on vertical or reciprocating axes. This brake arrangement is useful where the load must remain in place during a stop or power loss. The encoder and brake combination supports controlled motion, stable stopping behavior, and reliable restart performance. Power and feedback functions are integrated into one compact servo package, which helps the motor fit neatly into automated machinery with limited space.
