Product Description:

The MAC025C-0-QS-2-E/040-B-1/S004 is an AC servo motor engineered by Bosch Rexroth Indramat. It belongs to the MAC product line and is intended for use with analog drive amplifiers that command motion through current control. In automated machinery, the motor converts electrical commands into precise shaft motion for positioning and velocity-regulated axes. This operating role suits assembly stations, material-handling gantries, and other equipment that depends on repeatable rotary movement through frequent duty cycles.

Heat produced by the stator windings is removed through natural convection, so no fan or liquid circuit is fitted. This cooling method relies on ambient airflow and the housing surface area to carry heat away during operation. The motor generates velocity feedback through an internal tachogenerator, identified in the code as tacho feedback, and the resulting analog voltage allows a drive card to close a speed loop without digital encoders. A standard blocking brake is integrated, supplying mechanical holding torque whenever control power is removed so vertical or indexed loads remain fixed. The unit uses motor size C, which corresponds to the frame diameter and compatible flange pattern used within this motor family.

The short rotor stack is indicated by motor length 025, which helps keep reflected inertia low for lighter tooling and supports quick acceleration. Power conductors terminate through a connector on side B, a layout that can simplify cable routing when the drive is positioned to the right of the axis. Classified as a motor for analog drives, the unit accepts current commands that are proportional to the requested torque. This makes it suitable for retrofit systems that still rely on ±10 V references and separate analog control cards. The motor is part of the MAC AC Servo Motors series.
