Product Description:

The MAC041A-0-FS-4-E/050-A-1/WI671LV/S001 is a compact AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. As a rotary actuator paired with analog drive controllers, it converts command voltages into tightly regulated shaft motion for tasks such as positioning slides, indexing tables, or following master axes in automated machinery. Its mechanical dimensions, electrical winding, and feedback package are preset at the factory to streamline installation in cabinet-mounted or machine-mounted servo loops. This arrangement supports stable low-speed control and repeatable motion in compact industrial axes.

Inside the stator, the FS winding code identifies the wire gauge and turn count so that rated torque aligns with low- to medium-current analog amplifiers. Frame designation A indicates the smallest cross-section in the MAC platform, giving minimal inertia for rapid acceleration. The assembled stack length of 041 millimeters sets the active magnetic depth and continuous power output. Heat is released through natural convection, eliminating fans and simplifying maintenance schedules. Power is supplied through a connector on side A, an arrangement that keeps motor cabling away from moving components on most mounting faces.

The mechanical endbell carries a standard blocking brake that clamps the shaft when the drive disables torque, preventing drift on vertical axes during power loss. For motion feedback, the unit uses tachofeedback with an incremental or absolute encoder, providing speed and position signals for the paired analog drive. The primary signal path relies on an incremental encoder with standard mounting, giving differential TTL pulses that are compatible with legacy analog servo cards. The model is a motor for analog drives and suits retrofit applications that retain ±10 V command architecture. This feedback combination helps the drive respond consistently during speed regulation and point-to-point moves.
