Product Description:

The MAC041A-0-FS-2-E/050-B-0/S001 is a compact AC servo motor developed by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for industrial automation, this motor pairs with analog drive amplifiers to provide precise velocity and position control on smaller axes such as pick-and-place heads, tracking stations, or lightweight gantries. By converting electrical current into controlled rotational motion, the unit serves as a core actuator within closed-loop machinery where modest continuous torque, quick response, and stable motion are required.

Its electrical characteristics are set by the FS winding code, which establishes the phase resistance and inductance needed for compatible analog drives to deliver current in a stable manner. Thermal management relies on natural convection cooling, so heat is removed by surface radiation and airflow around the housing without external blowers or liquid circuits. The motor includes tacho feedback, which delivers a proportional voltage output for real-time speed reporting to the controller. Power is routed through a connector on side B, which helps simplify cable runs in cabinets where the shaft faces side A. The design has no blocking brake, so machines that must hold position at rest need mechanical clamping or drive-applied torque.

Dimensional integration is based on motor size 041 and motor length A, allowing the actuator to fit into tight spaces while still providing the magnetic stack needed for its rated output. Delivered as a motor for analog drives, it interfaces directly with classic velocity and current-loop amplifiers that use tachometer signals rather than digital encoders, making it suitable for legacy control platforms that still rely on analog feedback processing. The 041A configuration shares mounting points, shaft dimensions, and sealing features with other MAC motors of different power classes, which helps keep related mechanical interfaces consistent within the same machine design.
