Product Description:

The MAC041B-0-BS-2-E/050-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a compact drive component, the unit converts regulated motor current into controlled rotary motion for small axes in assembly systems, printing mechanisms, and light material-handling stations. Permanent magnets mounted on the rotor support responsive torque generation without requiring rotor excitation from an external power source. The motor works with an external controller to maintain stable speed or position as the applied mechanical load changes during operation.

Heat is removed through natural convection, so the installation should leave adequate clearance around the housing for unrestricted airflow. The integrated tachogenerator provides tacho feedback to the connected controller, allowing the velocity loop to correct speed deviations in real time. The motor has a size of 041 and a frame length of B, providing a compact housing for machinery with limited installation space. A centering diameter of 50 mm aligns the motor accurately with a machine flange, coupling, or gearbox input. Power conductors terminate at a connector on side B, which keeps the cable connection away from the driven shaft and supports orderly routing inside compact equipment. The connector arrangement also permits the cable to be secured near the housing, reducing movement at the electrical interface when the surrounding machine vibrates.

The motor has no blocking brake, so a vertical or gravity-loaded axis requires drive-applied holding torque or a separate mechanical locking device when motion stops. Configured as a motor for analog drives, the unit operates with compatible amplifiers that regulate motor current from analog velocity or position commands. This control arrangement supports smooth acceleration and deceleration in applications that use conventional analog motion architecture. Because the shaft is not held mechanically after drive power is removed, the connected machine must prevent unintended movement through its external braking or load-retention system. The compact frame and flange interface allow the motor to be installed close to the driven mechanism without adding a separate cooling assembly.
