Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI671LV is an AC servo motor manufactured by Bosch Rexroth Indramat and positioned within the MAC AC Servo Motors series. This model is supplied for use with analog servo drives where precise velocity and position control is required in industrial automation tasks such as material-handling axes, small pick-and-place modules, or positioning tables. By integrating standard feedback options and a compact frame, the motor provides a ready-to-install actuator that pairs with Indramat drive amplifiers. Its compact format also supports installation in machines where axis spacing and cable routing space are limited.

It employs winding code FS, which indicates the stator resistance, inductance, and current limits used by the drive for current-loop setup. Heat is removed only through natural convection, so the installation must allow sufficient airflow around the housing to keep winding temperature under control during continuous duty. The mechanical footprint is set by frame size 041 and motor length A, giving the unit a slim profile for compact machine frames. Power conductors exit through a connector on side A, permitting cable routing along the machine bed without tight bends. The arrangement also helps keep the power lead directed away from nearby moving parts.

For position verification, the unit supports tacho feedback, incremental encoder, or absolute encoder signals, and its standard assembly includes a incremental encoder with standard mounting so most analog drives can read velocity and incremental position directly. Within a system it is classified as a motor for analog drives, allowing use with classic command cards instead of fully digital interfaces. The housing is delivered with no blocking brake, so the axis must rely on external holding force or drive torque when power is removed. Omitting the brake lowers rotating inertia and can help shorten settling time in high-cycle motion.
