Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI668LV/S007 is manufactured by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. Designed for industrial automation, it functions as a torque-controlled rotary actuator that couples to external drive amplifiers, enabling closed-loop speed or position regulation on packaging lines, assembly stations, and material-handling axes. This arrangement lets the connected drive respond to changing load conditions during normal operation and maintain controlled motion on repeat-duty machine axes.

The motor uses winding code FS, which corresponds to the electrical characteristics required by compatible drive modules. Heat produced in the stator is removed through natural convection, so the housing must remain exposed to ambient air without forced ventilation. This cooling method keeps the installation simple because no separate blower or liquid circuit is required for basic operation. The overall mechanical depth matches frame length 041, and the motor has frame size A, which sets the flange diameter and shaft height for this housing. Power leads exit through a sealed connector on side B, allowing cable routing away from the load side and improving access inside control cabinets.

The motor has no blocking brake, so applications that must lock the shaft at power-off require an external brake or mechanical latch. The feedback channel supports tacho feedback with an incremental or absolute encoder, giving the drive electronics velocity and position data from the motor shaft. That signal arrangement supports regulated motion without adding a separate external transducer for basic axis feedback. It uses an incremental encoder with standard mounting, which keeps encoder centerlines concentric with the rotor to reduce runout errors. Classified as a motor for analog drives, the unit relies on current-mode amplifiers that use the feedback signals to regulate armature current for proportional torque production.
