Product Description:

The MAC041A-0-FS-3-E/050-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it supplies position and speed control to machine axes that rely on continuous analog command signals rather than fieldbus communication. This makes it suitable for established motion systems that use analog setpoints for velocity regulation and axis response. Its compact form factor lets builders place it in tight mechanical frames while still providing repeatable motion in automated assembly and material-handling stations.

The electromagnetic section uses winding code FS, which matches the voltage constant and current limits used by legacy analog drive controllers. The motor has a frame size of 041 and a motor length of A, which suits light-duty tasks in compact installations. Heat generated in the stator is removed by natural convection, eliminating the need for external blowers or liquid circuits. Because cooling is passive, the installation does not require separate fan wiring or added airflow hardware around the motor body. Power enters through a single plug in a connector on side B arrangement, which helps with cable routing when the opposite face is occupied by gearboxes or load couplings.

The mechanical build operates without a blocking brake, so vertical axes require an external clamp or drive torque to hold static loads. Rotor position is monitored through tacho feedback with a second shaft end, providing an analog speed signal and a physical stub for additional sensors or couplings. This arrangement supports auxiliary feedback devices or mechanical takeoffs when the application needs them at the rear of the motor. The centering diameter of 050 supports accurate alignment at the machine interface and helps the housing seat correctly against the mounting surface. Retrofit applications often use this layout on existing machines that retain compact analog servo hardware.
