Product Description:

The MAC041A-0-FS-2-E/050-A-1 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a compact permanent-magnet servo motor that couples directly to machine axes and supplies closed-loop torque and speed for material handling, packaging heads, and other positioning duties in industrial automation. Designed for use with analog drive controllers, the unit translates drive current into mechanical rotation without mechanical gearing, giving machine builders a simple electromechanical actuator for precision motion tasks.

The motor is built by Bosch Rexroth Indramat and relies on natural convection to transfer heat from the stator housing into the surrounding air, so no external blower or liquid circuit is required when mounted in a well-ventilated enclosure. Rotor velocity is monitored by integrated tacho feedback, which generates an analog voltage proportional to speed and lets analog drives maintain a stable velocity loop without additional sensors. Power conductors leave the stator through a connector on side A, allowing the cable to be routed along the machine frame while keeping the opposite face free for mechanical mounting. The stator uses winding code FS, which sets the resistance, inductance, and back-EMF constant so the drive can supply the correct current profile for the target torque range.

A standard blocking brake is fitted to clamp the rotor whenever the drive is disabled, helping prevent load drift on vertical or indexing axes. The active magnetic length is designated 041, a mid-stack size that balances continuous torque with low rotor inertia for rapid acceleration. Frame designation A determines the flange dimensions and shaft height, allowing interchange with other A-frame MAC motors. The unit is a motor for analog drives, which makes it suitable for legacy Rexroth controllers that issue ±10 V speed or current commands.
