Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI671LV is a synchronous servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for use with analog drive amplifiers in packaging machines, handling modules, and general automation axes. The motor converts drive commands into controlled torque and speed for applications that require accurate rotary motion. Its compact design allows it to operate as a positioning or speed-regulated actuator where installation space is limited.

This model relies on natural convection for heat dissipation, so the housing surface removes losses generated in the stator without requiring an external fan or liquid circuit. Winding code FS indicates the electromagnetic arrangement used to establish the motor’s voltage constant and torque gradient for a compatible analog drive stage. Power conductors leave the stator through a connector on side B, simplifying cable routing when the flange faces the operator side of a machine and helping separate high-current cables from feedback wiring. The motor has a frame size of 041, which provides a compact diameter for installation in tight spaces. Its A length keeps the axial profile short while providing the magnetic stack needed for the motor’s continuous torque output.

The motor has no blocking brake, so the drive or an external clamp must retain a static load when power is removed. Its feedback category supports tacho feedback with an incremental or absolute encoder, allowing the control system to obtain the speed or position data required by the application. This model includes an incremental encoder with standard mounting, which provides 90-degree phased square-wave signals compatible with traditional analog servo controllers. As a motor for analog drives, it uses transducers and connectors arranged to maintain low-noise analog signal paths. The feedback configuration is matched to the winding so the controller can process motor response without additional signal scaling.
