Product Description:

The MAC025A-0-WS-2-E/040-B-0 is an AC servo motor developed by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a drive element for closed-loop motion tasks, the unit works with compatible drive controllers to deliver controlled torque and speed in automated machinery. Its compact stator and permanent-magnet excitation convert electrical command signals into mechanical rotation for positioning axes, tool feeds, and conveyor sections in industrial automation cells. In typical use, an external amplifier regulates current to the windings so the motor can respond smoothly to changing speed and position demands. Its small form factor helps it fit machine sections where available installation space is limited.

Cooling relies on natural convection, so heat is dissipated through the housing without forced airflow, which is useful when the motor is mounted where ventilation space is limited. Rotor position and speed are reported through tacho feedback, allowing analog velocity loops to maintain stable shaft speed during routine operation. The stator uses winding code WS, which matches the electrical characteristics expected by compatible legacy MAC drives. The motor has no holding brake, so applications that must hold a load at standstill need an external brake or drive-applied holding torque.

The motor has size 025 and a compact length of A, giving it a small package for light-duty servo axes. Power conductors exit through a connector on side B, which can simplify cable routing when the mounting face is oriented the opposite way. This side-mounted connection can also help keep cable bends away from the machine face in tight spaces. As a motor for analog drives, it is intended for control systems that use analog command signals rather than digital network communication. This layout suits existing installations that still use established analog motion hardware.
