Product Description:

The MAC025A-0-WS-3-E/040-A-0/S006 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. This compact AC servo motor is intended for analog drive systems where speed and torque must be regulated with continuous feedback. In automated machinery, the unit turns electrical commands from an analog amplifier into controlled rotary motion for positioning tables, small actuators, and indexing devices. This operating style suits smaller axes that need repeatable response during frequent starts, stops, and speed changes.

This model is cooled solely by natural convection, so airflow around the housing must remain unobstructed to carry heat away without external blowers. Its frame uses a length code of 025, which sets stack height and affects torque capacity, and a motor size of A, which fixes the flange and shaft diameters for interchangeable mounting. These dimensions help the motor fit matching flanges and couplings on equipment designed for this frame. The design is supplied without a blocking brake, so any load-holding requirement relies on the drive or an external mechanical lock. The electromechanical characteristics are tied to winding code WS, which sets the phase resistance and inductance for use with the specified analog amplifier rating.

Rotor position feedback is handled by integrated tacho feedback, and the shaft is extended on the rear to form a second shaft end for coupling a separate encoder or fan if needed. Power conductors mate through a connector on side A, simplifying cable routing inside narrow enclosures. Because it is classified as a motor for analog drives, velocity is proportional to the applied armature voltage rather than digital pulse commands. This arrangement supports systems that use conventional analog control architecture and external amplifier regulation. The side-mounted connection and rear shaft extension can also help in compact installations where space around the motor is limited.
