Product Description:

The MAC041B-0-BS-2-E/050-B-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors product line. It belongs to a long-standing range used alongside analog servo controllers to regulate position and speed in automated machinery, pick-and-place modules, and light-duty handling axes. By converting electrical commands from a drive into rotary motion, the unit supplies closed-loop actuation for equipment that requires accurate shaft control without high thermal loads.

As a member of the MAC AC Servo Motors series, this model dissipates heat through natural convection, so no forced airflow or liquid circuit is needed when the enclosure is mounted in free air. Rotor position is reported to the drive by integrated tacho feedback, giving a proportional voltage that lets analog control loops maintain steady velocity and detect overspeed. A standard blocking brake is fitted to clamp the shaft whenever the drive disables torque, providing load-holding capability during power-off events. The frame uses size B, balancing limited mass with enough stator volume to develop meaningful continuous torque for smaller mechanical loads.

The mechanical stack is identified by the 041 motor length, indicating the shortest stator package in this family, which helps minimize inertia and support rapid acceleration profiles. Power conductors reach the stator windings through a connector on side B, and this orientation streamlines routing when the motor is installed against machine plates or gearboxes. Functionally, the device is classified as a motor for analog drives, making it suitable for legacy control architectures that modulate current and receive back-EMF feedback rather than digital encoder data. The compact stack and side-mounted connection help the motor fit into smaller axis layouts with limited installation space.
