Product Description:
The MAC025A-0-WS-3-E/040-D-0 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a compact permanent-magnet unit, it converts electrical power from an analog servo amplifier into precise rotary motion for positioning tables, feed axes, and auxiliary drives in industrial automation lines. Its responsive design supports applications that require high dynamics and repeatable velocity control. The motor’s compact housing also allows installation in machinery where the available mounting space is limited.
The stator uses the WS winding code, which provides voltage constants suited to 60 V class amplifiers while helping control thermal rise under rated load. Heat is removed through natural convection, so the housing dissipates winding heat without forced airflow from a fan. The motor size is 025, and its compact A length helps minimize rotor inertia for rapid acceleration and deceleration. Position and speed regulation are supported by integrated tachometer feedback, which returns a passive speed signal to the connected analog amplifier. A second shaft end provides a mechanical takeoff for an external sensor or manually operated encoder. The motor is supplied without a blocking brake, so vertical or suspended loads require an external holding device or continuous drive torque when stationary.
As a motor for analog drives, the unit connects directly to voltage-controlled amplifiers that accept a passive speed signal. This arrangement permits closed-loop speed correction without requiring a digital fieldbus adapter at the motor. Within the MAC AC Servo Motors platform, the flange dimensions support accurate alignment with compatible machine mounts and connected equipment. The keyway geometry provides positive torque transfer to a coupling, pulley, or gearbox input. Its connector orientation helps route power and feedback cables away from nearby moving parts while reducing cable strain. The permanent-magnet rotor supports responsive torque generation, while the integrated feedback system allows the amplifier to correct speed deviations caused by changing mechanical loads.
