Product Description:

The MAC041B-0-BS-4-E/050-B-0/WI651LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat and placed within the MAC AC Servo Motors series. Acting as a compact rotary actuator, it converts electrical input into controlled mechanical motion so automated packaging lines, pick-and-place gantries, and indexing tables can maintain precise torque and speed profiles. The device pairs with position-loop controllers to keep accuracy stable under variable load, changing duty cycles, and the repeatable motion demands found in continuous-process machinery.

Thermal management is handled solely by natural convection, so airflow around the housing must remain unobstructed to keep winding temperatures within limits during continuous duty. The motor has a frame size of 041, giving a compact diameter that balances torque density with installation space. Its B length indicates a medium stack within this frame, supporting continuous output without increasing mounting diameter. Power conductors enter through a connector on side B, simplifying cable routing when the motor is mounted to machines that present service access on the non-drive end. It is a motor for analog drives, so the winding design and feedback signals are compatible with legacy voltage-command amplifiers that reconstruct current loops internally.

Position data are supplied by an incremental encoder with standard mounting, which provides reference pulses for speed regulation and position control. The wiring can also support tacho feedback, incremental, or absolute encoder formats, allowing the motor to integrate with different control schemes without changing its basic mechanical layout. The motor has no blocking brake, so vertical-axis applications must rely on an external brake or static torque from the drive to hold loads when power is removed.
