Product Description:

The MAC041A-0-FS-3-E/050-A-0 is a small-frame servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog closed-loop drives, the device converts control currents into precise rotary motion that supports indexing tables, light pick-and-place modules, and other repetitive automation tasks in factory settings where stable speed regulation is required. Its mechanical layout and electrical interface couple directly to legacy analog amplifiers, giving machine builders a straightforward path to install speed-regulated AC axes in existing equipment. This arrangement suits older automation platforms that continue to use analog feedback loops rather than digital servo networks.

It relies on natural convection to carry heat away from the stator, so cabinet airflow or an external fan is unnecessary for continuous ratings under normal operating conditions. The shaft is supplied without a blocking brake, so position must be held through drive torque or an external clamp when power is removed. A combined feedback package adds tacho feedback for real-time speed measurement, and a second shaft end is present for mounting an auxiliary encoder or a mechanical load sensor. The added mounting point can support external feedback devices where more application-specific monitoring is needed.

Power is routed through a connector on side A, simplifying cable runs when the motor is positioned against bulkheads or gearboxes and when rear clearance is limited. Dimensional codes indicate a motor size of 041 and a motor length of A, resulting in a narrow body that fits compact gantries while still providing the torque expected from this frame. Electrical behavior is set by winding code FS, so the rated voltage, current, and back EMF match analog regulators used throughout assembly equipment and similar legacy motion systems.
