Product Description:

The MAC025A-0-WS-2-E/040-A-0 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed for closed-loop motion tasks, the unit works with analog drive controllers to regulate speed and torque in automated assemblies such as material-handling axes, pick-and-place heads, and compact positioning stages. By converting electrical energy into controlled mechanical rotation, the motor supports accurate and repeatable movement in equipment that depends on stable axis response. Its compact format makes it suitable for installations where mounting space is limited but precise motion is still required.

The motor uses natural convection for cooling, so heat dissipation depends on ambient airflow rather than forced ventilation. Position and velocity data are returned through integrated tacho feedback, allowing the analog drive to correct deviations during operation. In the dimensional code, the motor size is 025 and the frame length is A, which correspond to the physical envelope of this unit. Power conductors connect through a connector on side A, which can simplify cable routing when the drive end faces a machine wall. The motor is supplied with no blocking brake, so holding torque must be provided by the drive or by external mechanical means when power is removed.

In systems that still use proportional command voltages, the unit’s classification as a motor for analog drives supports direct electrical compatibility without added interface modules. The electromagnetic circuit uses winding code WS, which gives current and voltage characteristics suited to moderate-speed operation and repeatable servo response. This arrangement helps the paired amplifier maintain stable shaft motion during frequent starts, stops, and short positioning moves. It also allows the motor to serve compact automation axes that need predictable control behavior without auxiliary feedback adapters or separate cooling hardware.
