Product Description:

The MAC041A-0-FS-3-E/050-B-0/S006 is a compact AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is used as an electromechanical actuator in numerically controlled tooling, pick-and-place gantries, and packaging stations, where the shaft must follow commanded positions and speeds with repeatable accuracy. As a motor for analog drives, it works with external drive electronics that close the speed loop directly and deliver fast response to current commands. This arrangement supports smooth acceleration, stable low-speed operation, and consistent motion during frequent starts and stops on indexing, transfer, and positioning axes.

The FS winding code identifies the stator copper pattern and indicates electrical values suited for low-to-medium current analog amplifiers. Heat is removed by natural convection, so the housing dissipates losses without auxiliary fans or liquid cooling equipment. Feedback is provided by tacho feedback and a second shaft end, which places a tacho generator on the additional shaft stub to return a voltage proportional to speed. The motor has a 041 length and a compact A frame, giving it a small mechanical envelope for installations where axis space is limited. Its compact proportions help it fit smaller machine sections and reduce interference with nearby guide rails or tooling.

The motor has no blocking brake, so holding torque must be supplied electronically when the axis is stopped. Power enters through a connector on side B, which separates the power connection from the feedback hardware and can simplify cable routing in compact cabinets. This layout helps keep the motor compact while leaving room for the feedback arrangement at the opposite end. In applications with vertical or suspended loads, an external holding method is needed after power removal to prevent drift.
