Product Description:

The MAC025B-0-ZS-4-E/040-A-1/WI671LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it converts command signals into controlled shaft rotation for feeders, spindles, and pick-and-place axes that require accurate speed or position control. The motor is suited for automated machinery that depends on closed-loop motion and steady response during changing load conditions. Its operating concept fits systems in which an external drive amplifier regulates current and uses motor feedback to maintain the commanded motion profile.

Heat is removed by natural convection, so the housing needs unobstructed airflow during operation and does not rely on a separate cooling fan. A built-in blocking brake secures the shaft when power is removed, which helps prevent back-driving on vertical or suspended loads. The mechanical frame uses motor size 025 and motor length B, which establish the motor's physical envelope and active stack length. Electrical power enters through a plug-in connector on side A, allowing orderly cable routing in compact machine spaces and simplifying access at the connection point.

Speed and position feedback are supplied by an integrated tachogenerator together with an incremental encoder mounted at the rear of the motor. This arrangement allows the connected drive to monitor shaft movement continuously during acceleration, steady running, and stopping, while also supporting responsive correction when the load changes. An optional absolute encoder version may be used when the application needs additional position reference capability after startup. The rear-mounted feedback package keeps the sensing elements within the motor assembly, which reduces the need for separate external motion sensors on the axis.
