Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI673LV is a compact synchronous servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for pairing with analog drive controllers, the unit supplies controlled torque to indexing tables, pick-and-place heads, and similar motion axes found in automated assembly lines. By integrating electromagnetic windings, feedback sensors, and a sealed stator housing, the motor converts commanded current into accurate rotary displacement while maintaining dimensional compatibility with other members of the same series.

This configuration carries the winding designation FS, a code indicating the stator wire gauge and turns that establish its torque-to-current profile. Heat produced by those windings is dissipated through natural convection, so the motor can be mounted without forced-air ducts when ambient airflow is sufficient. Rotor position is reported by an incremental encoder with standard mounting, providing evenly spaced pulses that the drive uses for velocity and position loops. The motor has a length class of 041 and a frame size of A, allowing it to fit tight equipment envelopes while still supplying the continuous output expected from the MAC family.

Applications that demand holding torque during power loss must add an external brake because the motor has no blocking brake. Electrical supply conductors terminate through a connector on side A, streamlining cable routing when the motor is installed against machine panels. As a motor for analog drives, it interfaces with voltage-command amplifiers that rely on tacho or encoder feedback for closed-loop regulation. This unit is equipped with tacho feedback and an incremental or absolute encoder, allowing pulse-based or absolute position signals without changing the mechanical package.
