Product Description:

The MAC041B-0-BS-3-E/050-A-0 is an AC servo motor produced by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. The unit converts analog velocity or torque commands into controlled rotary motion, enabling precise indexing, feeding, and traverse functions in automated machinery. Its compact construction and brushless design allow it to serve axes that demand fast dynamic response while occupying minimal space within packaging, electronics assembly, or light material-handling systems. This type of motor is commonly paired with amplifier-based motion systems where consistent speed regulation is required across repeated cycles.

The motor uses natural convection for cooling, so external fans are unnecessary when free air can circulate around the housing. Power conductors exit through a connector on side A, which helps establish the cable route on right-hand installations. The motor length 041 code keeps rotor inertia low for applications that start and stop frequently. Frame dimensions follow the motor size B index used throughout the MAC family, giving the motor the same pilot and bolt pattern as other size-B models. Because there is no blocking brake, holding torque must be supplied by the drive or by an external mechanical lock during power-off conditions.

The integrated tacho feedback device supplies a proportional voltage that the drive uses to close the speed loop. The housing also provides a second shaft end, so auxiliary encoders or gearing can be added without changing the primary coupling. Classified as a motor for analog drives, the MAC041B accepts ±10 V reference signals and returns tachometer output over separate leads for use with legacy amplifier platforms. That combination supports retrofit systems that still depend on separate analog command and feedback wiring.
