Product Description:

The MAC041A-0-FS-4-E/050-B-1/WI651LV is an AC servo motor in the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Classified as a motor for analog drives, it converts ±10 V velocity or torque commands into controlled rotation for industrial automation axes. This form factor suits packaging, light assembly, and inspection equipment that need accurate motion control without digital fieldbus hardware. Its compact build and dedicated winding allow installation in tight machine frames while maintaining the response needed for midsize tooling, conveyor stations, and other axes that benefit from straightforward analog control. It is well suited to machines that use proven analog amplifiers and require repeatable servo response in a small footprint.

The motor uses winding code FS, which is matched to drive modules with moderate continuous current. The motor size is 041, which keeps inertia low while still providing enough torque for medium-duty axes. Heat is removed by natural convection, so no auxiliary fan is required and the housing should remain exposed to open airflow. A blocking brake holds the shaft when power is removed, which is useful on vertical or indexing stations. Electrical power enters through a connector on side B, which helps route cabling along the non-operator side of the machine and reduces tight cable bends during motion.

The feedback configuration uses tacho feedback with an incremental or absolute encoder, providing a speed signal for analog velocity loops or a position channel for more precise control. The compact length A keeps overall mass low while still providing adequate magnetic surface for the selected winding. As part of the MAC AC Servo Motors platform, the motor uses the mounting pattern, bolt circle, and shaft format common to that line. This arrangement supports integration into compact automation axes where consistent mechanical fit and mixed feedback capability are needed for speed regulation and position monitoring.
