Product Description:

The MAC041A-0-FS-4-E/050-A-1/WI671LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as the electromechanical element in analog drive systems, converting commanded current into precise shaft rotation for compact transfer stations, indexing tables, and auxiliary axes in industrial automation. Integrated rotor feedback supports tight velocity and position control loops while maintaining dimensions suitable for machine-mounted installations. The motor can provide controlled motion for equipment that requires repeatable acceleration, positioning, and speed regulation.

The stator uses the FS winding code, which indicates resistance and inductance values suited to the voltage and current limits of compatible analog amplifiers. Heat generated during continuous operation is removed through natural convection, so no external blower or liquid cooling circuit is required. The motor includes a standard blocking brake that holds the shaft when power is removed, which is useful for vertical or intermittent-motion axes. The three-phase supply is routed through a connector on side A, keeping the power connection accessible from one side of the machine. The motor has a frame size of 041, providing a compact mechanical envelope for installations with limited mounting space.

The motor has a frame length of A, which keeps axial overhang low on compact machine assemblies. As a motor for analog drives, its torque, back electromotive force, and commutation characteristics are compatible with analog drive controllers. Position and speed monitoring are handled through tachofeedback with an incremental or absolute encoder, allowing the connected controller to regulate shaft motion using real-time feedback signals. The installed feedback option is an incremental encoder with standard mounting, which supplies count information for position tracking while maintaining a conventional mechanical arrangement. This feedback configuration allows the drive to detect changes in rotor movement and correct deviations during operation without requiring a separate external measuring device.
