Product Description:

The MAC041B-0-QS-3-E/050-B-1/S001 is a brushless AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a drive component in closed-loop automation, this compact rotary unit converts commanded current into proportional shaft torque for tool positioning, pick-and-place movement, and indexing tasks on assembly lines and packaging machines. Its brushless construction supports smooth speed control during repeated starts and stops. In closed-loop service, it can respond quickly to command changes and maintain controlled motion through frequent acceleration and deceleration. The motor is suited to medium-inertia loads while maintaining fast response in repetitive duty cycles.

Heat is removed by natural convection, so no external blower or liquid circuit is needed. A blocking brake holds the shaft when power is removed, which helps prevent unwanted movement on vertical or overrunning axes. The feedback arrangement uses tacho feedback with a second shaft end, providing an analog speed signal while leaving the opposite side available for an auxiliary sensor or coupling. Power enters through a connector on side B, which can simplify cable routing when the motor rear faces upward or outward. The housing uses frame size B, giving a moderate flange size for compact machine layouts.

The 041 length code indicates a short housing that fits tighter machine spaces while keeping the magnetic stack needed for rated operation. Classified as a motor for analog drives, the unit works with controllers that issue command voltages rather than network-based motion messages. This arrangement suits existing motion systems that still use conventional servo amplifiers. The short housing also helps when the axis is mounted near guarding, transfer tooling, or compact gearbox assemblies. Standardized mounting interfaces help it fit compatible machine hardware without unusual mechanical adaptations.
