Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI652LV/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It delivers closed-loop rotary motion for pick-and-place modules, indexing tables, machine tools, and assembly equipment that require controlled positioning. The motor converts electrical commands from a compatible servo amplifier into regulated shaft position, speed, and torque. Its compact housing is suited to light industrial axes where installation space and moving mass are limited.

Winding code FS identifies the electrical configuration intended for moderate continuous current and limited peak demand in low-inertia applications. The motor has a size of 041 and a compact A length, which keeps its overall mass low while providing a practical mounting envelope for small machinery. Heat is removed through natural convection, so the installation does not require a fan or liquid cooling circuit. Adequate clearance around the housing is still necessary to prevent restricted airflow and excessive heat accumulation during continuous operation. Power conductors exit through a connector on side B, allowing cables to be routed toward the rear of the housing while leaving the front face clear for coupling to the driven load.

Rotor position is measured by a standard-mounted incremental encoder, which provides the controller with phase information for commutation and closed-loop motion regulation. The broader feedback configuration includes tachometer feedback with an incremental or absolute encoder, supporting applications that require velocity monitoring or additional position information. The motor has no holding brake, so an external brake, mechanical lock, or drive-generated torque must secure the load when the axis is stationary. This limitation is especially important for vertical or gravity-loaded mechanisms that could move when motor torque is unavailable. Its classification as a motor for analog drives indicates compatibility with MAC servo controllers that receive proportional voltage or current commands instead of commands sent through a digital fieldbus.
