Product Description:

Bosch Rexroth Indramat produces the MAC041A-0-FS-4-E/050-B-1/WI670LV/S001 as part of the MAC AC Servo Motors series. This electromechanical unit is a compact servo motor intended for voltage-controlled drive systems where precise velocity and torque regulation are needed. Within automated assembly cells and packaging machinery, the motor couples to a matched drive controller to turn electrical commands into controlled rotary motion while maintaining feedback for closed-loop positioning. Its compact frame keeps inertia low, allowing rapid acceleration of light loads used in pick-and-place axes and indexing tables without adding unnecessary mass.

Electrical performance is identified by winding code FS, which sets the motor’s nominal voltage, current, and torque constants so compatible analog drives can apply the correct gain settings. Thermal behavior is managed through natural convection, meaning heat leaves the stator surface without forced air or liquid circuits, so the installation must allow free airflow around the housing. Rotor position is measured by an incremental encoder with standard mounting, which provides evenly spaced pulses for speed loops and an index for homing routines. The motor size is 041, and frame length A gives the compact housing proportions used for matching flanges and related mounting parts.

For holding loads when power is removed, a standard blocking brake is integrated and releases when the drive enable signal energizes it. Additional motion feedback can be wired through the option labeled tacho feedback with an incremental or absolute encoder, allowing either a tachogenerator or a higher-resolution absolute sensor to be connected when the application requires it. Power conductors enter through a connector on side B, which keeps the cable exit away from the shaft area and supports axial cable routing. As a motor for analog drives, the unit remains compatible with legacy velocity amplifiers that use ±10 V command signals and tacho return circuits instead of digital buses.
