Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI671LV/S007 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for closed-loop axis control in machining centers, packaging lines, and handling modules, the unit translates drive commands into continuous rotary motion with precise speed and position regulation. This layout allows the motor to respond quickly to changing load demands during indexing, feed control, and synchronized transfer tasks. Because speed and position feedback are processed by the paired controller, the motor can serve as a compact actuator for repeatable motion sequences in general industrial automation.

Cooling is handled by natural convection, so the motor relies on free ambient airflow to remove heat and does not require an auxiliary fan. Position feedback is provided by an incremental encoder with standard mounting, giving the associated drive a fixed number of pulses per revolution for velocity and alignment loops. The electromagnetic section uses winding code FS, which corresponds to the electrical values expected by the matching drive and supports proper current control. Power is supplied through a connector on side A, which helps route cables away from nearby guards or transmission components. The motor has size 041, helping it fit installations where mounting space is limited.

The motor has length A, which keeps the housing short for compact machine layouts and leaves more room for couplings or adjacent axes. It has no blocking brake, so vertical loads must be supported by external means or by continuous drive torque when the axis is stationary. The absence of a brake also reduces added inertia at the shaft, which can help maintain responsive motion in applications that do not need load holding when power is removed. The unit is a motor for analog drives, making it suitable for legacy current-loop controllers rather than fully digital interfaces.
