Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI673LV/S007 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended to deliver precise rotary motion when paired with corresponding analog drive electronics, converting current commands into proportional torque so that conveyors, indexing tables, or light-duty assembly axes can position accurately within automated equipment. This arrangement places current regulation and motion control in the external drive amplifier while the motor supplies the electromechanical output required by the axis.

The winding code FS identifies the motor’s electrical characteristics and the current range expected from the drive. Frame designation A marks the smallest housing width in the MAC lineup, which helps the motor fit into compact machine spaces. Stack length index 041 indicates the magnetic core depth used for low-inertia applications that need modest continuous torque. Heat is removed through natural convection, so no forced-air or liquid cooling circuit is required and the housing should remain exposed to free airflow. Power is routed through a single plug with a connector on side B, which keeps the cable exit opposite the output shaft and helps separate wiring from moving machine elements.

The motor has no blocking brake, so any static holding force must be supplied by the drive or by external mechanical hardware. Position data are returned through an incremental encoder with standard mounting, providing evenly spaced pulse signals for velocity and displacement feedback in the control loop. A combined feedback option with tacho feedback and an incremental or absolute encoder is also available for applications that need additional signal formats. The unit is a motor for analog drives, so commutation and current control are handled by the external amplifier instead of onboard electronics. This layout supports use in established motion systems where the amplifier performs the closed-loop control functions.
