Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI668LV is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It converts drive current into controlled rotary motion for indexing tables, pick-and-place arms, and other motion stages that rely on precise acceleration and positioning. By pairing the motor with a compatible drive controller, users obtain fast dynamic response, repeatable speed regulation, and tight position tracking that are fundamental requirements in packaging, printing, and electronic assembly equipment.

The motor frame is categorized as size B, establishing the flange dimensions and bolt pattern suited for small to mid-range mechanical interfaces. Its axial stack, denoted as length 041, defines the active magnetic depth and therefore the continuous torque rating achievable from the same frame outline. Heat produced in operation is released through natural convection, so no external fan or liquid circuit is required and the housing must be exposed to ambient airflow. Power conductors terminate on a connector to side B, allowing cable routing that clears the opposite shaft end. The unit ships without a blocking brake, meaning static holding torque must be supplied by the drive or an external clamp when power is removed.

The position loop relies on a incremental encoder with standard mounting, giving the drive system uniformly spaced pulse feedback for velocity calculation as well as commutation alignment. For higher-resolution or direction-aware sensing, the internal wiring supports tachofeedback signals or an absolute encoder, so designers can match feedback fidelity to the demands of their application without changing the mechanical package. Because the motor is intended for analog drives, its feedback signals and winding design are matched to voltage-controlled amplifiers that balance cost with deterministic dynamic response in legacy and retrofit installations.
