Product Description:

The MAC025C-0-QS-3-E/040-B-0/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for point-to-point and speed-controlled tasks, converting amplifier commands into accurate shaft rotation for indexing tables, light pick-and-place actuators, and other motion elements used in industrial automation cells. The motor supports legacy motion systems that still rely on analog control, making it suitable for equipment where dependable speed regulation is required without a fully digital feedback architecture.

The motor has a size of 025 and a length code of C, giving it a short stator stack for installations where available space is limited. The housing relies on natural convection for cooling, so airflow around the ribs should remain unobstructed during continuous operation. Power conductors terminate on a connector on side B, which helps keep cable loops away from nearby tooling when the flange faces forward. The motor has no blocking brake, so gravity-loaded axes require an external clamp or counterbalance when holding force is needed after power removal.

Speed feedback is supplied by tacho feedback mounted on the rear frame, providing an analog voltage proportional to motor speed for real-time regulation. A second shaft end opposite the drive coupling allows the addition of a handwheel or auxiliary encoder without disturbing the primary load connection. The unit is described as a motor for analog drives, confirming compatibility with ±10 V amplifiers commonly used in legacy motion systems. Because the feedback device provides a direct analog speed signal, the paired amplifier can regulate velocity without the digital encoder processing used by newer servo platforms. The extra shaft extension is also useful when the driven end is coupled directly to a pulley or gearbox and separate access is needed for adjustment or measurement.
