Product Description:

The MAC025C-0-QS-2-E/040-A-0 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is an AC servo motor intended for closed-loop motion tasks where an analog drive controller dictates speed and position. Within automated handling or light machining stations, the motor converts drive current into controlled rotary movement so that tooling or fixtures can follow programmed profiles with repeatable accuracy. In these systems, the motor works with the controller's feedback loop to maintain stable acceleration, deceleration, and speed regulation during repeated moves. Its format suits smaller automation stations where responsive motion matters more than maximum continuous output.

The stator windings are cooled solely by natural convection, so heat is released through the housing without forced airflow. For velocity monitoring, the motor is equipped with tacho feedback, allowing an analog controller to compare commanded and actual speed in real time. The motor has a size code of 025 and a frame length of C, which determine the active iron length and overall stack height. Power conductors exit through a connector on side A, which simplifies cable routing when the drive cabinet is located on that side of the machine. This combination of cooling, feedback, and housing dimensions helps set mounting clearances, cable exit direction, and thermal behavior within compact machine spaces. It is appropriate for applications that cycle frequently but do not require very high continuous torque.

The motor is supplied with no blocking brake, so holding torque must be provided by the drive or by external restraints when the axis is at rest. Because it is specified as a motor for analog drives, signal scaling and speed loops are handled in the drive electronics rather than inside the motor feedback circuit itself. That separation keeps the motor focused on electromechanical conversion while control functions remain in the matched drive hardware. The absence of an integral brake also reduces added wear components at the motor body. This layout is useful on compact axes where cabinet-based analog control is still used for regulated motion.
