Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI670LV/S006 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for tightly regulated motion axes found in packaging lines, pick-and-place gantries, and light machine tools, where precise torque and speed control are required under digital or analog drive supervision. Its compact frame and internal rotor design allow direct coupling to gear stages or belt transmissions without enlarging the mechanical envelope of the host machine. This layout also suits compact axes where available mounting space is limited and consistent response is needed during repeated starts and stops.

The motor uses winding code FS, which sets the coil resistance, inductance, and rated current so a matching drive amplifier can be selected. The size code 041 indicates a short body that reduces mass and inertia for faster acceleration in low-to-medium power axes. Frame designation A sets the flange dimensions and shaft height, enabling interchange with other motors that share the same mounting pattern. Heat is removed by natural convection, so the housing must be positioned in free airflow and no blower kit is needed. The short housing also fits installations near slides, guards, or adjacent machine frames where extra motor length would interfere with surrounding components. Power enters through a connector on side B, which simplifies cable routing inside compact electrical cabinets.

The motor has no blocking brake, so external clamps or drive torque must secure vertical loads during shutdowns. Position sensing is handled by an incremental encoder installed with standard centering tolerances, delivering phase-shifted tracks for speed loops while minimizing radial runout. This arrangement lets the connected drive process speed and position feedback without a separate sensor assembly at the axis. For applications that demand higher resolution or long-term drift monitoring, the feedback harness supports tachofeedback or absolute encoder signals without additional adapters. The motor is classified as a motor for analog drives, meaning its feedback and sinusoidal commutation are compatible with classic ±10 V command interfaces used by legacy Indramat drive modules.
