Product Description:

The MAC041B-0-BS-4-E/050-A-1/WI674LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for positioning and velocity control in automated machinery, the unit converts electrical drive commands into precise rotary motion that can be regulated by analog servo amplifiers. It is well suited for indexing tables, light gantry axes, and material-handling fixtures where compact dimensions and repeatable motion are important. Its layout also supports installations where low mass and predictable response help maintain smooth axis behavior.

The frame follows a size B designation, giving a moderate cross-section that balances torque output with installation space. Its stator stack carries a length 041 code, which indicates the active magnetic length used by this motor. Heat produced during duty cycles is removed by natural convection, so the housing depends on unobstructed surrounding airflow rather than forced cooling. Power is supplied through a connector on side A, which can simplify cable routing when the shaft faces forward. During standstill or power-off states, a standard blocking brake holds the shaft in place to help prevent drift on vertical or load-biased axes.

Signal integrity is supported by the feedback devices included with this model. It uses tacho feedback for speed regulation, and the feedback arrangement can also work with an absolute encoder when multi-turn position capture is required by the application. The unit is a motor for analog drives, so it pairs with legacy current-controlled amplifiers that use analog command signals. For applications that require relative position tracking, the integrated incremental encoder with standard mounting provides quadrature pulses that a controller can count directly without extra interface hardware.
