MAC041A-0-FS-4-E/050-A-0/WI668LV

The Bosch Rexroth Indramat MAC041A-0-FS-4-E/050-A-0/WI668LV is a compact AC servo motor in the MAC AC Servo Motors series. Designed for closed-loop motion axes, the unit supplies repeatable torque and speed profiles to legacy analogue controllers in automated handling, packaging, and assembly stations. Its mechanical frame and electrical interface align with other MAC motors, allowing the device to be mounted in tight spaces while maintaining the response required for precision industrial positioning tasks, and it is often applied in pick-and-place modules, lightweight actuators, and scanning tables.

This model is supplied with no blocking brake, so any load-holding function must be provided by an external mechanism or by drive torque. Heat is removed through natural convection, meaning the housing fins dissipate losses without forced airflow, an advantage in sealed cabinets. The internal copper matches the FS winding code, which defines resistance and inductance suitable for moderate current loops. With a motor length of 041, the active stack is short, minimizing inertia, and the frame size A sets a flange pattern that fits smaller gear trains.

For wiring, the power leads exit via a connector on side A, simplifying routing when the motor is placed against vertical plates. Position and velocity signals are derived through the factory-installed tachofeedback incremental or absolute encoder, providing analog speed feedback in conjunction with drive-based control loops. The secondary channel uses an incremental encoder with standard mounting so differential quadrature signals are available for high-resolution counting. As a motor for analogue drives, this feedback pairing ensures compatibility with legacy controller families while maintaining contemporary accuracy.
