Product Description:

The MAC041A-0-FS-4-E/050-A-0/WI670LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and organized under the MAC AC Servo Motors series. Designed for integration with analog drive controllers, the unit supplies controlled torque and speed to automated machinery that requires tight following error and repeatable positioning. Its compact 041 frame length and A-size stator allow installation in equipment where axial space is restricted while still maintaining the dynamic response expected from the MAC family. It is intended for machines that need repeatable starts, stops, and speed changes without requiring a large motor body.

Heat generated in the stator is removed by natural convection, eliminating the need for external blowers or liquid circuits. Because cooling is passive, the housing must release heat directly to the surrounding air during operation. Power enters the motor through a connector on side A, so cable runs can be oriented along the drive side of a machine frame and kept clear of nearby couplings. The active magnetic stack uses length code 041, and the housing corresponds to size A, which helps the motor fit machine interfaces intended for this compact frame. Electromechanical behavior is matched to MAC-series amplifiers through winding code FS, which sets the coil resistance and inductance for stable current control across the intended operating range.

The motor has no shaft-holding brake, so any static load must be secured by external means when power is removed. For motion feedback, the motor supports tacho feedback, incremental encoder, or absolute encoder signals, allowing the connected drive to use either speed-proportional voltage or digital position data. This flexibility allows the same motor platform to support applications centered on speed regulation or more detailed axis positioning. Its declared product category is motor for analog drives, confirming compatibility with voltage-commanded amplifiers rather than fully digital interfaces. The shaft end is factory-fitted for an incremental encoder with standard mounting, so the feedback device can be installed without an additional adapter plate.
